[PATCH V2 0/3] mt7988: initial DT changes

[Rafał Miłecki]

From: Rafał Miłecki <rafal@milecki.pl>

This work is based on linux-next content and was successfully verified
using "dtbs_check". It's initial code for MT7988A that will get extended
as we get more bindings available (pinctrl is big blocker right now).

AngeloGioacchino, Matthias: is this something you could queue in
git://git.kernel.org/pub/scm/linux/kernel/git/mediatek/linux
for v6.9?

[PATCH V2 2/3] arm64: dts: mediatek: Add initial MT7988A and BPI-R4

[Rafał Miłecki]

From: Rafał Miłecki <rafal@milecki.pl>

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.

Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

V2: Drop thermal zones & reserved memory from .dtsi (those don't belong
    there and we also need thermal controller first). Fix compatible.
