Subject: [PATCH AUTOSEL 6.4 33/54] ASoC: atmel: Fix the 8K sample parameter in I2SC master
Date: Sun, 13 Aug 2023 11:49:12 -0400 [thread overview]
Message-ID: <20230813154934.1067569-33-sashal@kernel.org> (raw)
In-Reply-To: <20230813154934.1067569-1-sashal@kernel.org>
From: Guiting Shen <aarongt.shen@gmail.com>
[ Upstream commit f85739c0b2b0d98a32f5ca4fcc5501d2b76df4f6 ]
The 8K sample parameter of 12.288Mhz main system bus clock doesn't work
because the I2SC_MR.IMCKDIV must not be 0 according to the sama5d2
series datasheet(I2SC Mode Register of Register Summary).
So use the 6.144Mhz instead of 12.288Mhz to support 8K sample.
