Subject: [PATCH 2/2] arm64: dts: mediatek: Add initial MT7988A and BPI-R4

From: Rafał Miłecki <[email protected]>

MT7988A (AKA MediaTek Filogic 880) is a quad-core ARM Cortex-A73
platform designed for Wi-Fi 7 devices (there is no wireless on SoC
though). The first public MT7988A device is Banana Pi BPI-R4.

Many SoC parts remain to be added (they need their own bindings or
depend on missing clocks). Those present block however are correct and
having base .dtsi will help testing & working on missing stuff.

Why is the compatible describing MT798*6*A instead of MT7988A? Please fix.

This is board specific (actually, it is bootloader specific!), so please move it
to your board dts(i).

Those thermal zones will not work, as they have no thermal-sensors - as this
node is right now, it will produce a probe error and nothing else: please
either drop it entirely or add support for the thermal sensors (lvts or auxadc?)
and fix this node to use them.

Active cooling is board specific. Keep only critical/hot trips in the SoC DT.

Hi

thanks Rafal for making the first loop of Dts-patches and splitting it and Angelo for first review.
Just my 2c on the thermal-part.

it is LVTS and i upstreamed dt-binding and driverchange already, but it also needs a (infracfg-)reset which
i try to upstream soon after infracfg clock driver appear in next (imho daniels patch merged in subsystem tree today).

so also the infracfg-node will be needed in next round, if thermal part should be part of it (else not much is in the dtsi at this time).

@rafal how do we sync our work? what is your codebase?
i currently work on daniels wip tree, but it does not contain your current splitting...
maybe daniel can include your splitted dts patches?

i already tried to fix some binding-issues in the full dts(i)....
waiting for vendor about clocks for mmc which are currently not matching actual binding (and using mt7986 compatible).

In the future, just give me the message-id in these cases.
