[PATCH 01/60] pinctrl: renesas: r8a77470: Reduce size for narrow VIN1 channel

From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: 2021-12-23 14:42:21
Also in: linux-renesas-soc
Subsystem: pin control subsystem, pin controller - renesas, the rest · Maintainers: Linus Walleij, Geert Uytterhoeven, Linus Torvalds

The second video-in channel on RZ/G1C has only 12 data lanes, but the
pin control driver uses the vin_data union, which is meant for 24 data
lanes, thus wasting space.

Fix this by using the vin_data12 union instead.

This reduces kernel size by 96 bytes.

Fixes: 50f3f2d73e3426ba ("pinctrl: sh-pfc: Reduce kernel size for narrow VIN channels")
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
All other Renesas pin control drivers were fixed, but RZ/G1C was
forgotten, as RZ/G1C video-in support went in just before these fixes.
