Thanks. Do you have any suggestions for patch 2? Should I merge the
description in patch 2 into this file?

The full dts for this series looks like this:

                smc: smc at 23e400000 {
                        compatible = "apple,t8103-smc", "apple,smc";
                        reg = <0x2 0x3e400000 0x0 0x4000>,
                                <0x2 0x3fe00000 0x0 0x100000>;
                        reg-names = "smc", "sram";
                        mboxes = <&smc_mbox>;

                        smc_gpio: gpio {
                                gpio-controller;
                                #gpio-cells = <2>;
                        };
                };

but the fuller version in the asahi linux tree looks like:

		smc: smc at 23e400000 {
			compatible = "apple,t8103-smc", "apple,smc";
			reg = <0x2 0x3e400000 0x0 0x4000>,
				<0x2 0x3fe00000 0x0 0x100000>;
			reg-names = "smc", "sram";
			mboxes = <&smc_mbox>;

			smc_gpio: gpio {
				gpio-controller;
				#gpio-cells = <2>;
			};

			smc_rtc: rtc {
				nvmem-cells = <&rtc_offset>;
				nvmem-cell-names = "rtc_offset";
			};

			smc_reboot: reboot {
				nvmem-cells = <&shutdown_flag>, <&boot_stage>,
					<&boot_error_count>, <&panic_count>, <&pm_setting>;
				nvmem-cell-names = "shutdown_flag", "boot_stage",
					"boot_error_count", "panic_count", "pm_setting";
			};
		};

So whatever is decided for the gpio node would eventually also apply
to the other nodes too.

Thanks.
