Subject: [RFC PATCH 02/34] ASoC: sun8i-codec: LRCK is not inverted on A64
Date: Mon, 17 Feb 2020 00:42:18 -0600 [thread overview]
Message-ID: <20200217064250.15516-3-samuel@sholland.org> (raw)
In-Reply-To: <20200217064250.15516-1-samuel@sholland.org>
On the A64 (tested with the Pinephone), the current code causes the
left/right channels to be swapped during I2S playback from the CPU on
AIF1, and breaks DSP_A communication with the modem on AIF2.
Trusting that the comment in the code is correct, the existing behavior
is kept for the A33.
Cc: stable@kernel.org
Fixes: ec4a95409d5c ("arm64: dts: allwinner: a64: add nodes necessary for analog sound support")
