[PATCH v4 2/3] riscv: dts: sophgo: cv180x: Add PWR_GPIO controller
From: Chen-Yu Yeh
Date: Tue Jul 21 2026 - 22:32:15 EST
The CV180x/CV181x family has an additional DesignWare APB GPIO
controller (PWR_GPIO) located in the always-on power domain at
0x5021000. Add the node so that boards can reference GPIOs in this
bank, such as status LEDs.

Changes since v3:
- Move the pwr_gpio node to follow unit-address ordering (Inochi Amaoto)
