[PATCH v2 2/4] dt-bindings: clock: mediatek: add clock controllers of MT7988
Daniel Golle

Mon Nov 20 09:18:55 PST 2023
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 at makrotopia.org>

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"
