[PATCH v4 0/7] Add minimal MT8365 and MT8365-EVK support

[PATCH v4 0/7] Add minimal MT8365 and MT8365-EVK support

[Bernhard Rosenkränzer]

This adds minimal support for the MediaTek 8365 SOC and the EVK reference
board, allowing the board to boot to initramfs with serial port I/O.

v4:
  - Remove pins-are-numbered references that have been holding things up
    now that the patches removing it from dt-bindings have landed in linux-next

v3:
  - Remove a number of components that are not yet supported (they will
    come back alongside the corresponding drivers)
  - Address issues found by dt_binding_check (mostly fixing pinctrl
    bindings)
  - Address issues pointed out in comments
  - Reorder patches

v2:
  - Add missing dt-bindings documentation
  - Small cleanups addressing issues in v1 pointed out by Krzysztof Kozlowski

+              The specific driving setup is controlled by E1E0EN.
+              When E1=0/E0=0, the strength is 0.125mA.
+              When E1=0/E0=1, the strength is 0.25mA.

+              EN is used to enable or disable the specific driving setup.

[PATCH v4 7/7] arm64: dts: mediatek: Initial mt8365-evk support

[Bernhard Rosenkränzer]

From: Fabien Parent <fparent@baylibre.com>

This adds minimal support for the Mediatek 8365 SOC and the EVK reference
board, allowing the board to boot to initramfs with serial port I/O.
