[PATCH 0/5] ARM: dts: rcar2: Configure pull up for GPIO keys

[Geert Uytterhoeven]

	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!
