While the sm1 is very close to the g12a/b family, somethings apply differently on the g12a/b and not the sm1.

2019-08-09arm64: dts: meson-g12a: add cpus OPP tableNeil Armstrong
Add the OPP table taken from the vendor u200 and u211 DTS. The Amlogic G12A SoC seems to available in 3 types : - low-speed: up to 1,8GHz - mid-speed: up to 1,908GHz - high-speed: up to 2.1GHz And the S905X2 opp voltages are slightly higher than the S905D2 OPP voltages for the low-speed table. This adds the conservative OPP table with the S905X2 higher voltages and the maximum low-speed OPP frequency. The values were tested to be stable on an Amlogic U200 Reference Board, SeiRobotics SEI510 and X96 Max Set-Top-Boxes running the arm64 cpuburn at [1] and cycling between all the possible cpufreq translations and checking the final frequency using the clock-measurer, script at [2].

2019-08-09arm64: dts: move common G12A & G12B modes to meson-g12-common.dtsiNeil Armstrong
To simplify the representation of differences betweem the G12A and G12B SoCs, move the common nodes into a meson-g12-common.dtsi file and express the CPU nodes and differences in meson-g12a.dtsi and meson-g12b.dtsi. This separation will help for DVFS and future Amlogic SM1 Family support. The sd_emmc_a quirk is added in the g12a/g12b since since it's already known the sd_emmc_a controller is fixed in the next SM1 SoC family.

2019-08-05arm64: dts: meson-g12a: add missing dwc2 phy-namesNeil Armstrong
The G12A USB2 OTG capable PHY uses a 8bit large UTMI bus, and the OTG controller gets the PHY but width by probing the associated phy. By default it will use 16bit wide settings if a phy is not specified, in our case we specified the phy, but not the phy-names. The dwc2 bindings specifies that if phys is present, phy-names shall be "usb2-phy". Adding phy-names = "usb2-phy" solves the OTG PHY bus configuration.
