Hi Geert,
Thank you for your patch!
> From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
> Subject: [PATCH/RFT] pinctrl: renesas: rzv2m: Handle non-unique subnode
> names
>
> The eMMC and SDHI pin control configuration nodes in DT have subnodes
> with the same names ("data" and "ctrl"). As the RZ/V2M pin control
> driver considers only the names of the subnodes, this leads to
> conflicts:
>
> pinctrl-rzv2m b6250000.pinctrl: pin P8_2 already requested by
> 85000000.mmc; cannot claim for 85020000.mmc
> pinctrl-rzv2m b6250000.pinctrl: pin-130 (85020000.mmc) status -22
> renesas_sdhi_internal_dmac 85020000.mmc: Error applying setting, reverse
> things back
>
> Fix this by constructing unique names from the node names of both the
> pin control configuration node and its child node, where appropriate.
