[PATCH 0/3] arm64: dts: nuvoton: Add pinctrl and gpio nodes for MA35D1

[Jacky Huang]

From: Jacky Huang <ychuang3@nuvoton.com>

This patch series adds pinctrl and gpio nodes to the device tree of
the Nuvoton MA35D1 SoC. Additionally, it includes pin configuration
for UART nodes now that the pinctrl node is available.
