Subject: [PATCH AUTOSEL 4.9 06/11] ASoC: max98090: remove 24-bit format support if RJ is 0
Date: Tue, 25 Jun 2019 23:45:56 -0400 [thread overview]
Message-ID: <20190626034602.24367-6-sashal@kernel.org> (raw)
In-Reply-To: <20190626034602.24367-1-sashal@kernel.org>
From: Yu-Hsuan Hsu <yuhsuan@chromium.org>
[ Upstream commit 5628c8979642a076f91ee86c3bae5ad251639af0 ]
The supported formats are S16_LE and S24_LE now. However, by datasheet
of max98090, S24_LE is only supported when it is in the right justified
mode. We should remove 24-bit format if it is not in that mode to avoid
triggering error.
