Hi all, This patches series follows up on the work started with "[PATCH] ARM: dts: koelsch: Configure pull-up for SOFT_SW GPIO keys"[1], and explicitly configures pull-ups for pins used for GPIO keys without external pull-up resistors on R-Car Gen2 boards, preceded by a small cleanup. Currently GPIO keys rely on the initial states of these pins, which fortunately match the expectations, but it is better to be explicit. To actually make a difference, this depends on "[PATCH 00/12] pinctrl: renesas: Add more bias pinconf support"[2]. Note that it is safe to apply this series before [2] has landed, as pinctrl_bind_pins() does not consider -ENOTSUPP a fatal error. It would be great if people with access to the hardware could do similar tests like I did on Koelsch[3]. I hope to queue this in renesas-devel for v5.14. Thanks for your comments!
