Subject: [PATCH v3 2/4] dt-bindings: clock: mediatek: add clock controllers
 of MT7988
Message-ID: <def05aac79ddff872d3e56698b736cb445f14116.1701823757.git.daniel@makrotopia.org>

Precedence: bulk

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"
