Subject: [PATCH v2 3/4] arm64: dts: nuvoton: Add pinctrl support for ma35d1
From: Jacky Huang <ychuang3@...oton.com>
Add 'pinctrl' node and 'gpioa' ~ 'gpion' nodes to the dtsi of ma35d1
SoC and describe default pin configurations.
Enable all UART nodes presented on som and iot boards, and add pinctrl
function settings to these nodes.
