Thanks for noticing this. There is no need to repost to update the subject, but for reference I would prefer the prefix to be "ARM: dts: alt:". Assuming there are no other changes I can fix that up when queuing up this change. I am wondering if this should be queued up as a fix for v4.9 and in turn v4.8-stable. Or if it should just be queued up for v4.10. In the case of the former I'd advocate adding the following tag (again no need to repost just to update this): Fixes: 56ed4bb984ac ("pinctrl: sh-pfc: r8a7794: Add DU pin groups") > arch/arm/boot/dts/r8a7794-alt.dts | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/arch/arm/boot/dts/r8a7794-alt.dts b/arch/arm/boot/dts/r8a7794-alt.dts > index 8d1b35a..9d65fb3 100644 > --- a/arch/arm/boot/dts/r8a7794-alt.dts > +++ b/arch/arm/boot/dts/r8a7794-alt.dts > @@ -165,8 +165,8 @@ > pinctrl-names = "default"; > > du_pins: du { > - groups = "du1_rgb666", "du1_sync", "du1_disp", "du1_dotclkout0"; > - function = "du"; > + groups = "du1_rgb666", "du1_sync", "du1_disp", "du1_clk0_out"; > + function = "du1"; > }; > > scif2_pins: scif2 { > -- > 2.7.4 > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel >
