Sorry. The commit being referred to is (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4a8573abe965115bc5b064401fd669b74e985258) commit 4a8573abe965115bc5b064401fd669b74e985258 Author: Andy Gross <agross@xxxxxxxxxxxxxx> Date: Thu Jun 12 14:34:10 2014 -0500 spi: qup: Remove chip select function This patch removes the chip select function. Chip select should instead be supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI core assert/deassert the chip select as it sees fit. The chip select control inside the controller is buggy. It is supposed to automatically assert the chip select based on the activity in the controller, but it is buggy and doesn't work at all. So instead we elect to use GPIOs. Signed-off-by: Andy Gross <agross@xxxxxxxxxxxxxx> Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> Will update the commit log and repost the patches.
