From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

The SD/MMC block on the RZ/V2H(P) ("R9A09G057") SoC is similar to that
of the R-Car Gen3, but it has some differences:
- HS400 is not supported.
- It has additional SD_STATUS register to control voltage,
  power enable and reset.
- It supports fixed address mode.

To accommodate these differences, a SoC-specific 'renesas,sdhi-r9a09g057'
compatible string is added.

- Dropped regulator node.

v3->v4
- Dropped 'renesas,sdhi-use-internal-regulator' property
- Moved 'vqmmc-regulator' to the top level

v2->v3
- Renamed vqmmc-r9a09g057-regulator object to vqmmc-regulator
- Added regulator-compatible property for vqmmc-regulator
- Added 'renesas,sdhi-use-internal-regulator' property

v1->v2
- Moved vqmmc object in the if block
- Updated commit message

Thanks for your patch, which is now commit 32842af74abc8ff9
("dt-bindings: mmc: renesas,sdhi: Document RZ/V2H(P) support") in
mmc/next.

This looks wrong to me.
Did you want to add it to the clocks constraint, like the third hunk
in v4[1], and was it mangled in a rebase?

Oouch, yes you are correct, this had to go in the clock constraint.

I am happy to apply a fix on top for that.
