[PATCH v3 21/21] riscv: dts: starfive: jhb100: Add pinctrl nodes

Tue Jun 2 22:53:47 PDT 2026
Add pinctrl nodes for starfive JHB100 SoC. They contain
pinctrl_per0/pinctrl_per1/pinctrl_per2/pinctrl_per2pok/pinctrl_per3/
pinctrl_sys0/pinctrl_sys0h/pinctrl_sys1/pinctrl_sys2.
Simultaneously add the pinctrl reference for uart6.
