From 4e9e07c5675706983ed649cfb92521a4d8aa1d6d Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 17 Oct 2018 01:54:33 +0000 Subject: [PATCH] ASoC: pcm3168a: add hw constraint for capture channel LEFT_J / I2S only can use TDM. commit 594680ea4a394 ("ASoC: pcm3168a: add hw constraint for channel") commit 3809688980205 ("ASoC: pcm3168a: add HW constraint for non RIGHT_J") added channel constraint for it, but, it was only for playback. This patch adds constraint for capture.
