[PATCH 2/2] pinctrl: sh-pfc: r8a77990: Add voltage switch operations for SDHI

[Marek Vasut]

From: Takeshi Kihara <takeshi.kihara.df@renesas.com>

This patch supports the {get,set}_io_voltage operations of SDHI.

This operates the IOCTRL30 register on the R8A77990 SoC and makes
1.8V/3.3V signal voltage switch possible.

Looks good from a high-level point of view. Didn't check the actual
values. I trust Shimoda-san and Geert for that:

These must be part of this patch, since adding
+		SH_PFC_PIN_GROUP(sdhi0_data1),
entries grows the size of the array. If you were to split this patch,
the PFC driver would break, as the size of the array won't match the
size of the content.
