Subject[PATCH] arm64: dts: meson-g12-common: add spicc controller nodes
Date
This adds the controller and pinctrl nodes for the Amlogic G12A SPICC
controllers.

Kevin,

This depends on the CLKID_SPICC0_SCLK and CLKID_SPICC1_SCLK introduced
in https://lore.kernel.org/linux-arm-kernel/20200219084928.28707-2-narmstrong@baylibre.com/
