Commit Message

Daniel Golle Dec. 12, 2023, 3:18 a.m. UTC 
  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>

v5:
 * drop use of ti,syscon-reset and hence also syscon and simple-mfd
   compatibles from mt7988-ethwarp clock controller which now got the
   clock controller provide the reset(s).

v4:
 * add subnodes for controllers acting as MFD

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"

No underscores in compatibles. At least for new ones, because you cannot
touch the old.

else: also valid?

Maybe there is no point to have it in this binding?
