I will rename it.

Yes, I will split them.

It should actually be 3.3V, I will fix it and rename to vcc3v3_usb_modem

I will change it to vcc3v3_pi6c.
But there seems to be a warning here, maybe phy-supply is missing in rockchip,pcie3-phy.yaml?

/tmp/build/arch/arm64/boot/dts/rockchip/rk3568-photonicat.dtb: phy@...c0000: 'phy-supply' does not match any of the regexes: 'pinctrl-[0-9]+'
        from schema $id: http://devicetree.org/schemas/phy/rockchip,pcie3-phy.yaml#

pcie30x1m0_pins seems to conflict with sdmmc0, I changed it to pcie30x1m1_pins

I will remove them

When I add clocks-name, check_dtbs gives me a warning

/tmp/build/arch/arm64/boot/dts/rockchip/rk3568-photonicat.dtb: bluetooth: 'clock-names' does not match any of the regexes: 'pinctrl-[0-9]+'
        from schema $id: http://devicetree.org/schemas/net/bluetooth/qualcomm-bluetooth.yaml#

Maybe clock-name is missing in qualcomm-bluetooth.yaml?

Thanks for your review, I will fix all problems in PATCH v2.
