That is not correct: the driver does not match against "renesas,gpio-r8a7778". Hence this breaks using a new DTS and an old kernel (which we may decide not to care about for R-Car Gen1, though). But at least the DTS change should be postponed until commit d10bbd156926e65d ("gpio: rcar: add gen[123] fallback compatibility strings") has hit mainline. > Signed-off-by: Simon Horman <horms+renesas@verge.net.au> > --- > arch/arm/boot/dts/r8a7778.dtsi | 10 +++++----- > 1 file changed, 5 insertions(+), 5 deletions(-) > > diff --git a/arch/arm/boot/dts/r8a7778.dtsi b/arch/arm/boot/dts/r8a7778.dtsi > index 8f3156c0e575..b3975e4c75dd 100644 > --- a/arch/arm/boot/dts/r8a7778.dtsi > +++ b/arch/arm/boot/dts/r8a7778.dtsi > @@ -88,7 +88,7 @@ > }; > > gpio0: gpio@ffc40000 { > - compatible = "renesas,gpio-r8a7778", "renesas,gpio-rcar"; > + compatible = "renesas,gpio-r8a7778", "renesas,rcar-gen2-gpio"; ...

Use newly added R-Car GPIO Gen1 fallback compat string in place of now deprecated non-generation specific R-Car GPIO fallback compat string in DT of r8a7778 SoC. This should have no run-time effect as the driver matches against the per-SoC compat string before considering the fallback compat string.
