Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk fixes from Stephen Boyd:
 "Some more clk driver fixes and one core framework fix:

   - A handful of TI driver fixes for bad of_node_put() and incorrect
     parent names

   - Rockchip rk3228 aclk_gpu* creation was interfering with lima GPU
     work so we use a composite clk now

   - Resuming from suspend on Tegra Jetson TK1 was broken because an
     audio PLL calculated an incorrect rate

   - A fix for devicetree probing on IM-PD1 by actually specifying a clk
     name which is required to pass clk registration

   - Avoid list corruption if registration fails for a critical clk"
