Subject: arm64: dts: allwinner: sun55i-a523: Add pinmux for spi0 on PJ pins
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b1bbf38922de947144a48dafa0f0e4ac8e24444a;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: allwinner: sun55i-a523: Add pinmux for spi0 on PJ pins

The Avaota A1 board uses spi0 on the PJ pins to connect a SPI NAND
chip.

Add the full set of pins. Even though this board doesn't use CS1, other
boards may do so in the future.
