also, this looks like a pinctrl driver option, why in soc/?
Add support of voltage control to Renesas PFC driver. Voltage register
mappings have been added to r8a77951 and r8a77961 SoCs.
Allow 'power-source' property for 'renesas,rcar-pfc' node. This property
will be used for configuring IO voltage on appropriate pin. For now it
is possible to have only two voltages: 1.8 and 3.3.
Note: it is possible to change voltage only for SD/MMC pins on r8a77951
and r8a77961 SoCs.

you're right, done!
added!
To be able to disable this feature for debugging purposes, and with the config, we don't need to care about the existence of PFC SoC changes for other boards (like ARM32 or Gen4).
Okay, I'll wait, but I don't see any major merging conflicts between these two PRs. |
