[alsa-devel] [PATCH v2] ASoC: rsnd: fix DALIGN register for SSIU
From: Nilkanth Ahirrao anilkanth@jp.adit-jv.com
The current driver only sets 0x76543210 and 0x67452301 for DALIGN. This doesn’t work well for TDM split and ex-split mode for all SSIU. This patch programs the DALIGN registers based on the SSIU number.
