From 5ede19c58a1ec274b28e03a76b855c3c55ab6f11 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 8 Dec 2014 11:23:11 +0100 Subject: [PATCH 0001/1377] ASoC: wm8750: Make VREF a VMID instead of OUTPUT widget Commit 04489eeb02a4 ("ALSA: wm8750: add missing VREF output") added the previously missing VREF widget. And while adding the widget as OUTPUT widget silences the error of the missing widget it should have rather been a VMID widget. The VREF widget is only used internally as a source for the VREF input of the Out3 Mux. Selecting that input means that the path should be kept powered up at the VREF/VMID voltage, but that there is no actual audio signal. Using a VMID widget will do this, whereas using a OUTPUT widget will simply cause the path to completely power down.

This adds a driver for this. There are 2 channels, currently this driver only supports chan0 since there are no boards known to use chan1. This has been tested on an olimex a10s-olinuxino-micro, a13-olinuxino, and a20-olinuxino-micro.

This makes the code a bit shorter and cleaner. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.

For this reason a INPUT or OUTPUT widget that is really not connected needs to be explicitly marked as so. Setting the card's fully_routed flag will cause the ASoC core, once that all widgets and routes have been registered, to go through the list of all widgets and mark all INPUT and OUTPUT that are not externally connected as non-connected. This essentially negates the default behaviour of treating INPUT or OUTPUT widgets without external routes as sources or sinks. This patch takes a different approach while getting the same result. Instead of first marking INPUT and OUTPUT widgets as sinks/sources and then later marking them as non-connected, just never mark them as a sink or a source if the fully_routed flag is set on a card. This requires a lot less code and also results in a slightly faster card initialization since there is no need to iterate over all widgets and check whether the INPUT and OUTPUT widgets are connected or not.

get/set_selection The crop and selection pad ops are duplicates. Replace all uses of get/set_crop by get/set_selection. This will make it possible to drop get/set_crop altogether.

This is its GUID for BGR 8:8:8. The UVC 1.5 spec[2] only defines GUIDs for YUY2, NV12, M420 and I420. This seems to be an extension documented in the Microsoft Windows Media Format SDK[3] - or at least the Media Format SDK was the only hit that Google gave when searching for the GUID. This Media Format SDK defines this GUID as corresponding to `MEDIASUBTYPE_RGB24`. Note though, the XI100DUSB outputs BGR e.g. byte-reversed. I don't know if its the capture device in error or Microsoft mean BGR when they say RGB.

It made motion event never appear in my installation. That code is complicated, so I couldn't figure out quickly how to fix it, so dropping it seems better to me.

A comment has also been added that makes it explicit that drivers shouldn't use this field. Additional bits have been added to the debug flag to be more fine-grained when debugging, especially when dealing with streaming ioctls and read, write and poll. You want to enable those explicitly to prevent flooding the log when streaming unless you actually want to do that.

This results in the filter being disabled in the hardware and not re-enabled until the filter is set again using sysfs. Fix in store_protocols() by still re-applying the filter whenever the change_protocol() driver callback succeeded. The problem can be reproduced with the img-ir driver by setting a filter, and then setting the protocol to the same protocol that is already set: $ echo nec > protocols $ echo 0xffff > filter_mask $ echo nec > protocols After this, messages which don't match the filter were still being received.

The previous workaround for these devices has been left in place in case the driver is not compiled into the kernel or in case some other device with the same PNP ID is not recognized by the driver yet still has the same problems with the device probing code.

Currently this will result in msbits being set to whatever the last rule set it to. This patch updates the behavior of the rule to choose the minimum (other than zero) of all the installed rules.

But often the number of most significant bits is not sample format specific, but rather a absolute limit. E.g. the PCM interface might accept 32-bit and 24-bit samples, but the DAC has a 16-bit resolution and throws away the LSBs. In this case for both 32-bit and 24-bit format msbits should be set to 16. This patch extends snd_pcm_hw_constraint_msbits() so that a wildcard constraint can be setup that is applied for all formats with a sample width larger than the specified msbits. Choosing the wildcard constraint is done by setting the sample width parameter of the function to 0.

The later is only the case for snd_wss_pcm() for snd_cs4236_pcm() and it is possible to get the same PCM object by accessing the pcm field of the snd_wss struct that was passed as the first parameter. This function removes the last parameters from the functions mentioned above and updates the callers which used it to use chip->pcm instead. This allows us to slightly simplify the functions since they don't have to check and set the last parameter anymore which makes the code slightly shorter and cleaner.

The SPI framework has now been enhanced so that even normal spi_sync() calls won't suffer these effects so we don't need to handle this in ASoC and in fact it can be more efficient not to since we don't need to set up and tear down the buffers needed to manage asynchronous I/O. The async completions that DAPM does are left in place so drivers can use them, they are very cheap if there is no asynchronous work queued.

I2S transmitter has MMIO-based interface that resembles that of the OpenCores I2S transmitter. I2S transmitter is always a master on I2S bus. There's no specialized audio DMA, sample data are transferred to I2S transmitter FIFO by CPU through memory-mapped queue interface.

Accessing indices beyond array size (OS will send TUR, INQUIRY.. commands upto device index 255), may return valid LD value and that particular SCSI command will be SUCCESS and creating SCSI device for non existing target(VD). For legacy firmware (64 VD firmware), invalidates LD (by setting LD value to 0xff) in LdTgtIdtoLd[] array for device index beyond 127, so that invalid LD(0xff) value should be returned beyond device index beyond 127.

Earlier reserved commands for non SCSI IO frames was set to 32, so with this implementation, increased per controller "can_queue". Behavior of MFI controllers will remain unchanged. 2) Optimize the code related to per controller's 'can_queue' setting.

To maintain backwards compatibitliy with current usage of the DT binding, this is only done when PIN_MAP_TYPE_INVALID is passed to the parsing function as type. Also, a new helper 'pinconf_generic_dt_node_to_map_all()' is introduced, which can be used by drivers as generic callback for dt_node_to_map() to leverage the new feature.

To achieve this 'struct pinctrl_desc' is extended to pass custom pinconf option to the core. In order to pass this kind of information, the related data structures - 'struct pinconf_generic_dt_params', 'pin_config_item' - are moved from pinconf internals to the pinconf-generic header. Additionally pinconfg-generic is refactored to not only iterate over the generic pinconf parameters but also take the parameters into account that are provided through the driver's 'struct pinctrl_desc'. In particular 'pinconf_generic_parse_dt_config()' and 'pinconf_generic_dump' helpers are split into two parts each. In order to have a more generic helper that can be used to process the generic parameters as well as the driver-specific ones. v2: - fix typo - add missing documentation for @conf_items member in struct - rebase to pinctrl/devel: conflict in abx500 - rename _pinconf_generic_dump() to pinconf_generic_dump_one() - removed '_' from _parse_dt_cfg() - removed BUG_ONs, error condition is handled in if statements - removed pinconf_generic_dump_group() & pinconf_generic_dump_pin helpers - fixed up corresponding call sites - renamed pinconf_generic_dump() to pinconf_generic_dump_pins() - added kernel-doc to pinconf_generic_dump_pins() - add kernel-doc - more verbose commit message Signed-off-by: Soren Brinkmann Tested-by: Andreas Färber Signed-off-by: Linus Walleij --- drivers/pinctrl/nomadik/pinctrl-abx500.c | 2 +- drivers/pinctrl/pinconf-generic.c | 182 +++++++++++++---------- drivers/pinctrl/pinconf.c | 4 +- drivers/pinctrl/pinconf.h | 22 +-- drivers/pinctrl/pinctrl-rockchip.c | 2 +- drivers/pinctrl/pinctrl-tz1090-pdc.c | 2 +- drivers/pinctrl/pinctrl-tz1090.c | 2 +- drivers/pinctrl/sh-pfc/pinctrl.c | 2 +- include/linux/pinctrl/pinconf-generic.h | 18 +++ include/linux/pinctrl/pinctrl.h | 9 ++ 10 files changed, 141 insertions(+), 104 deletions(-) diff --git a/drivers/pinctrl/nomadik/pinctrl-abx500.c b/drivers/pinctrl/nomadik/pinctrl-abx500.c index 3d6d97228523ce..1806b24faa14e6 100644 --- a/drivers/pinctrl/nomadik/pinctrl-abx500.c +++ b/drivers/pinctrl/nomadik/pinctrl-abx500.c @@ -914,7 +914,7 @@ static int abx500_dt_subnode_to_map(struct pinctrl_dev *pctldev, } } - ret = pinconf_generic_parse_dt_config(np, &configs, &nconfigs); + ret = pinconf_generic_parse_dt_config(np, pctldev, &configs, &nconfigs); if (nconfigs) { const char *gpio_name; const char *pin; diff --git a/drivers/pinctrl/pinconf-generic.c b/drivers/pinctrl/pinconf-generic.c index 21b3d90ebb2d1c..e0886665b70a27 100644 --- a/drivers/pinctrl/pinconf-generic.c +++ b/drivers/pinctrl/pinconf-generic.c @@ -27,17 +27,6 @@ #include "pinctrl-utils.h" #ifdef CONFIG_DEBUG_FS - -struct pin_config_item { - const enum pin_config_param param; - const char * const display; - const char * const format; - bool has_arg; -}; - -#define PCONFDUMP(a, b, c, d) { .param = a, .display = b, .format = c, \ - .has_arg = d } - static const struct pin_config_item conf_items[] = { PCONFDUMP(PIN_CONFIG_BIAS_DISABLE, "input bias disabled", NULL, false), PCONFDUMP(PIN_CONFIG_BIAS_HIGH_IMPEDANCE, "input bias high impedance", NULL, false), @@ -60,22 +49,25 @@ static const struct pin_config_item conf_items[] = { PCONFDUMP(PIN_CONFIG_OUTPUT, "pin output", "level", true), }; -void pinconf_generic_dump_pin(struct pinctrl_dev *pctldev, - struct seq_file *s, unsigned pin) +static void pinconf_generic_dump_one(struct pinctrl_dev *pctldev, + struct seq_file *s, const char *gname, + unsigned pin, + const struct pin_config_item *items, + int nitems) { - const struct pinconf_ops *ops = pctldev->desc->confops; int i; - if (!ops->is_generic) - return; - - for (i = 0; i < ARRAY_SIZE(conf_items); i++) { + for (i = 0; i < nitems; i++) { unsigned long config; int ret; /* We want to check out this parameter */ - config = pinconf_to_config_packed(conf_items[i].param, 0); - ret = pin_config_get_for_pin(pctldev, pin, &config); + config = pinconf_to_config_packed(items[i].param, 0); + if (gname) + ret = pin_config_group_get(dev_name(pctldev->dev), + gname, &config); + else + ret = pin_config_get_for_pin(pctldev, pin, &config); /* These are legal errors */ if (ret == -EINVAL || ret == -ENOTSUPP) continue; @@ -85,56 +77,46 @@ void pinconf_generic_dump_pin(struct pinctrl_dev *pctldev, } /* Space between multiple configs */ seq_puts(s, " "); - seq_puts(s, conf_items[i].display); + seq_puts(s, items[i].display); /* Print unit if available */ - if (conf_items[i].has_arg) { + if (items[i].has_arg) { seq_printf(s, " (%u", pinconf_to_config_argument(config)); - if (conf_items[i].format) - seq_printf(s, " %s)", conf_items[i].format); + if (items[i].format) + seq_printf(s, " %s)", items[i].format); else seq_puts(s, ")"); } } } -void pinconf_generic_dump_group(struct pinctrl_dev *pctldev, - struct seq_file *s, const char *gname) +/** + * pinconf_generic_dump_pins - Print information about pin or group of pins + * @pctldev: Pincontrol device + * @s: File to print to + * @gname: Group name specifying pins + * @pin: Pin number specyfying pin + * + * Print the pinconf configuration for the requested pin(s) to @s.

Boot hangs when pinctrl information is present in DT but no driver available. - add #defines to get rid of magical constants - add commas at end of initializers - separate changes in mach-zynq in separate patch - add driver specific io-standard DT property - refactored pinconf set function to not require arguments for argument-less properties - squash other patches in - support for IO-standard property - support for low-power mode property - migration to pinconf_generic_dt_node_to_map_all() - use newly created infrastructure to add pass driver-specific DT params to pinconf-generic changes since RFC: - use syscon/regmap to access registers in SLCR space - rebase to 3.18: rename enable -> set_mux - add kernel-doc - support pinconf - supported attributes - pin-bias: pull up, tristate, disable - slew-rate: 0 == slow, 1 == fast; generic pinconf does not display argument Signed-off-by: Soren Brinkmann Tested-by: Andreas Färber Signed-off-by: Linus Walleij --- drivers/pinctrl/Kconfig | 8 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-zynq.c | 1176 ++++++++++++++++++++++++++++++++ 3 files changed, 1185 insertions(+) create mode 100644 drivers/pinctrl/pinctrl-zynq.c diff --git a/drivers/pinctrl/Kconfig b/drivers/pinctrl/Kconfig index d014f22f387a71..67c8db92745480 100644 --- a/drivers/pinctrl/Kconfig +++ b/drivers/pinctrl/Kconfig @@ -191,6 +191,14 @@ config PINCTRL_PALMAS open drain configuration for the Palmas series devices like TPS65913, TPS80036 etc. +config PINCTRL_ZYNQ + bool "Pinctrl driver for Xilinx Zynq" + depends on ARCH_ZYNQ + select PINMUX + select GENERIC_PINCONF + help + This selectes the pinctrl driver for Xilinx Zynq. + source "drivers/pinctrl/berlin/Kconfig" source "drivers/pinctrl/freescale/Kconfig" source "drivers/pinctrl/intel/Kconfig" diff --git a/drivers/pinctrl/Makefile b/drivers/pinctrl/Makefile index c7139ba195fece..6c28bd623612e1 100644 --- a/drivers/pinctrl/Makefile +++ b/drivers/pinctrl/Makefile @@ -35,6 +35,7 @@ obj-$(CONFIG_PINCTRL_XWAY) += pinctrl-xway.o obj-$(CONFIG_PINCTRL_LANTIQ) += pinctrl-lantiq.o obj-$(CONFIG_PINCTRL_TB10X) += pinctrl-tb10x.o obj-$(CONFIG_PINCTRL_ST) += pinctrl-st.o +obj-$(CONFIG_PINCTRL_ZYNQ) += pinctrl-zynq.o obj-$(CONFIG_ARCH_BERLIN) += berlin/ obj-y += freescale/ diff --git a/drivers/pinctrl/pinctrl-zynq.c b/drivers/pinctrl/pinctrl-zynq.c new file mode 100644 index 00000000000000..62534234da78a1 --- /dev/null +++ b/drivers/pinctrl/pinctrl-zynq.c @@ -0,0 +1,1176 @@ +/* + * Zynq pin controller + * + * Copyright (C) 2014 Xilinx + * + * Sören Brinkmann + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This is meant to replace the current interface which is based on module symbol lookups. Note that currently we keep the existing behavior and pin the i915 module while the hda driver is loaded. Using the component interface allows us to remove this dependency once support for dynamically enabling / disabling the HDMI functionality is added to the driver. v2: - change roles between the hda and i915 components (Daniel) v3: - rename display_component to audio_component (Daniel) v4: - move removal of i915_powerwell.h from this patch to the next (Takashi) - request_module fails if module support isn't enabled, so ignore any error it returns and depend on the following NULL check of the component ops (Takashi) - change over to using dev_* instead of pr_* (Takashi) Signed-off-by: Imre Deak Reviewed-by: Takashi Iwai Signed-off-by: Daniel Vetter --- sound/pci/hda/hda_i915.c | 142 +++++++++++++++++++++++++++----------- sound/pci/hda/hda_intel.c | 5 +- sound/pci/hda/hda_intel.h | 4 ++ 3 files changed, 106 insertions(+), 45 deletions(-) diff --git a/sound/pci/hda/hda_i915.c b/sound/pci/hda/hda_i915.c index 66acd09f5da179..714894527e06a5 100644 --- a/sound/pci/hda/hda_i915.c +++ b/sound/pci/hda/hda_i915.c @@ -18,8 +18,10 @@ #include #include +#include +#include +#include #include -#include #include "hda_priv.h" #include "hda_intel.h" @@ -31,32 +33,33 @@ #define AZX_REG_EM4 0x100c #define AZX_REG_EM5 0x1010 -static int (*get_power)(void); -static int (*put_power)(void); -static int (*get_cdclk)(void); - int hda_display_power(struct hda_intel *hda, bool enable) { - if (!get_power || !put_power) + struct i915_audio_component *acomp = &hda->audio_component; + + if (!acomp->ops) return -ENODEV; - pr_debug("HDA display power %s \n", - enable ?

Subject: [PATCH 0415/1377] atyfb: mark DMI system id table as __initconst We can mark the DMI system id table as __initconst by using a helper variable that'll tell us if we need to unregister the reboot notifier in atyfb_exit() instead of matching the DMI system id again. This frees up ~680 bytes of runtime memory, the DMI table occupies.
