Hi Geert

Thank you for the patch

> According to the hardware team, R-Car H3 ES1.0 and R-Car M3-W have a
> rare quirk where powering down the A3IR, A3VC, and A3VP power domains
> requires an extra delay of 1 µs.  So far upstream never handled that,
> but the BSP has a fix[1].  As support for R-Car H3 ES1.x was dropped in
> v6.4, only R-Car M3-W still needs to be handled.
