From 7a733e060bd20edb63b1f27f0b29cf9b184e0e8b Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Wed, 6 Dec 2023 15:52:33 +0100 Subject: [PATCH] spi: cadence: revert "Add SPI transfer delays" The commit 855a40cd8ccc ("spi: cadence: Add SPI transfer delays") adds a delay after each transfer into the driver's transfer_one(). However, the delay is already done in SPI core. So this commit unnecessarily doubles the delay amount. Revert this commit.
