[PATCH] dt-bindings: mtd: physmap: add 'clocks' and 'power-domains'

[PATCH] dt-bindings: mtd: physmap: add 'clocks' and 'power-domains'

[Wolfram Sang]

Physmap supports minimal PM since commit 0bc448b49e8a017e ("mtd: maps:
physmap: Add minimal Runtime PM support"), so support it also when used
in DT configurations.

Tested with a Renesas Genmai board (RZ/A1). Passes 'dt_binding_check'
and 'dtbs_check'. Supersedes my original approach "[RFC PATCH 0/4] ARM:
dts: renesas: mtd-rom has no clock and power domain":

Applied to nand/next, thanks!

[1/1] dt-bindings: mtd: physmap: add 'clocks' and 'power-domains'
      commit: 4e7a83ed83120858f676007706197aa5594d4dd9

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
Miquèl
