Subject[PATCH v4 07/15] ARM: shmobile: genmai reference dts: Add RSPI nodes
Date
From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>

Add pinctrl and SPI devices for RSPI on Genmai.

On this board, only rspi4 is in use. Its bus contains a single device
(a wm8978 audio codec), for which no bindings are defined yet.

Signed-off-by: Geert Uytterhoeven <geert+renesas@linux-m68k.org>
Cc: devicetree@vger.kernel.org

v4:
- No changes
v3:
- No changes
v2:
- Use generic "codec" instead of specific "wm8978" node name.
