Subject: [PATCH 5.13 401/800] pinctrl: renesas: r8a7796: Add missing bias for PRESET# pin
From: Geert Uytterhoeven <geert+renesas@...der.be>
[ Upstream commit 2cee31cd49733e89dfedf4f68a56839fc2e42040 ]
R-Car Gen3 Hardware Manual Errata for Rev. 0.52 of Nov 30, 2016, added
the configuration bit for bias pull-down control for the PRESET# pin on
R-Car M3-W. Add driver support for controlling pull-down on this pin.
Fixes: 2d40bd24274d2577 ("pinctrl: sh-pfc: r8a7796: Add bias pinconf support")
