I will submit a v2 with: [ renesas,rza1-pinctrl.txt ] Required properties: - compatible this shall be "renesas,r7s72100-ports" for RZ/A1H, "renesas,r7s72101-ports" for RZ/M or "renesas,r7s72102-ports" for RZ/A1L [ r7s72100.dtsi ] pinctrl: pin-controller@fcfe3000 { compatible = "renesas,r7s72101-ports", "renesas,r7s72100-ports"; [ pinctrl-rza1.c ] No change from V1 Unless you say something different, I will submit a V2 in a little while. As always, thank you for your guidance! Chris
