Subject: arm64: dts: allwinner: a523: Add I2S2 pins on PI pin group
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a9050236f81c43fc2eaa2e13098c7fb53c3aba34;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: allwinner: a523: Add I2S2 pins on PI pin group

The Radxa Cubie A5E exposes I2S2 through the PI pin group on the 40-pin
GPIO header.

Add a pinmux setting for it so potential users can directly reference
it.
