Subject: [PATCH v1 1/2] ARM: dts: at91: Map MCLK for wm8731 on at91sam9g20ek
Date: Fri, 25 Mar 2022 15:27:14 +0000 [thread overview]
Message-ID: <20220325152715.1597893-2-broonie@kernel.org> (raw)
In-Reply-To: <20220325152715.1597893-1-broonie@kernel.org>
The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the
PCK0 output of the SoC and is expected to be set to 12MHz. Previously
this was mapped using pre-common clock API calls in the audio machine
driver but the conversion to the common clock framework broke that so
describe things in the DT instead.
Fixes: ff78a189b0ae55f ("ARM: at91: remove old at91-specific clock driver")
Signed-off-by: Mark Brown <broonie@kernel.org>
