Generally I'm fine with this. I'm wondering if we should go one step
further by decommissioning Meson6 support?
To be specific here, I'm thinking of removing MACH_MESON6 from
arch/arm/mach-meson/Kconfig and deleting meson6{.dtsi,-atv1200.dts}

I don't have any boards with Meson6 SoC, there's no upstream GPIO,
pinctrl, clock, MMC, <you name it> driver for that SoC either.
So all we have upstream is the ability to boot to initramfs and use
serial console(s).
If someone is interested in Meson6 support they should bring it back
along with a few more patches for upstream support of further
peripherals.


Best regards,
Martin
