    Subject[PATCH 5.13 401/800] pinctrl: renesas: r8a7796: Add missing bias for PRESET# pin
    Date
    From: Geert Uytterhoeven <geert+renesas@glider.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")
