[alsa-devel] [PATCH v6 1/2] ALSA: ASoC: davinci-mcasp: don't configure AFSX direction in DIT mode
From: Yegor Yefremov yegorslists@googlemail.com
AFSX won't be used in DIT mode. The related pins are AHCLKX and the data pins.

Channel size settings will be made at the end of davinci_mcasp_hw_params() routine and thus overwrite frame format settings made for DIT mode. This patch fixes this issue by taking op_mode into account. Tested with official PSP 3.2 kernel and sii9022a HDMI transmitter.

Applied both, thanks. Please use subject lines matching the subsystem.
