[PATCH v3 2/4] dt-bindings: clock: mediatek: add clock controllers of MT7988

Daniel Golle
2023-12-06T00:57:19Z

Add various clock controllers found in the MT7988 SoC to existing
bindings (if applicable) and add files for the new ethwarp, mcusys
and xfi-pll clock controllers not previously present in any SoC.

Signed-off-by: Daniel Golle <daniel@makrotopia.org>
---
v3:
* move clock bindings to clock folder
* drop ti,syscon-reset from bindings and example
* merge mcusys with topckgen bindings

v2:
* dropped unused labels
* add 'type: object' declaration for reset-controller found in new
ethwarp controller and represented as ti,syscon-reset
* rebase on top of
"dt-bindings: arm: mediatek: move ethsys controller & convert to DT schema"
