Subject: [PATCH] arm64: dts: qcom: kodiak: Add LPASS I2S2 pinctrl definitions
Date: Mon, 23 Mar 2026 06:40:47 -0300	[thread overview]
Message-ID: <20260323095247.92890-1-val@packett.cool> (raw)

Add the pinctrl definitions to configure gpio10-gpio13 of the lpass_tlmm
for I2S output.

Signed-off-by: Val Packett <val@packett.cool>

Similar to ff9c117c32bc6ace7 which just landed, this is for the other MI2S
interface on there. It is the Senary MI2S, so actually using it requires
the series from [1] and then more changes on top, but I have sound working
on my device with it, so let's get this DT chunk in first / at the same time
as the other prereqs land as well.

Thanks,
~val
