Yes, I would like to get input as I don't have the other platforms using
"pinconf,single":

$ git grep 'compatible = "pinconf-single"' arch/
arch/arm/boot/dts/am33xx-l4.dtsi:                                       compatible = "pinconf-single";
arch/arm/boot/dts/hi3620.dtsi:                  compatible = "pinconf-single";
arch/arm/boot/dts/pxa3xx.dtsi:                  compatible = "pinconf-single";
arch/arm64/boot/dts/broadcom/stingray/stingray-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hi3798cv200.dtsi:                 compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hi6220.dtsi:                      compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hi6220.dtsi:                      compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey960-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey960-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey960-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey960-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey960-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey970-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey970-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey970-pinctrl.dtsi:                    compatible = "pinconf-single";
arch/arm64/boot/dts/hisilicon/hikey970-pinctrl.dtsi:                    compatible = "pinconf-single";

NOTE: the arch/arm/boot/dts/am33xx-l4.dtsi was patched by me from
"pinctrl-single" to "pinconf-single.  But, I think for upstream
submission I would need to move that to one of the beaglebone specific
dts files like am335x-bone-common.dtsi.

I believe this pinctrl-single.c patch fixes a flaw in return logic and
is useful regardless of whether beaglebone adopts "pinconf,single".
However, I would very much like to get input from others in case my
analysis is too narrow.

Thanks,
Drew
