arm64: dts: rockchip: add pinctrl for clk-generator GPIO
From: Heiko Stuebner <heiko.stuebner@...> Date: Mon, 8 Jul 2024 12:57:29 +0200
Commit-Message
While specific driver in the Linux-Kernel handles GPIOs gracefully without matching pinctrl entries, this might not be true for other operating systems. So having pinctrl entries makes the hardware-description more complete. The somewhat similar rk3588-jaguar board has a pinctrl entry already, so also add one for rk3588-tiger.
