Yeah, believe me, I did a faceplant when I saw your pull request come by at the same time I discovered this issue. ;) In particular, AnilKumar's user leds patch would need to be adjusted for this change.

Ok, I went ahead and posted a series that applies to your for_3.7/dts branch and Anil's series. That's assuming his v7 series is taken "as is" after the leds-gpio/pinctrl discussion comes to conclusion. I see Tony acked it aside from that discussion.

Yes, my biggest concern here was the coming frustration that the end "user" or system integrator would have with these labels not matching the docs that have been around for a year. It would be !sane to have somebody look at a schematic and then write their dts with a value that doesn't match the h/w. That would run counter to the fundamental requirement that DT is a description of the hardware. The user led patch was already the first example of that where the comments mentioned gpio1 in the pinmux data but the data referenced the gpio2 label. -Matt > > Signed-off-by: Matt Porter <mporter@ti.com> > > --- > > arch/arm/boot/dts/am33xx.dtsi | 8 ++++---- > > 1 file changed, 4 insertions(+), 4 deletions(-) > > > > diff --git a/arch/arm/boot/dts/am33xx.dtsi b/arch/arm/boot/dts/am33xx.dtsi > > index bb31bff..1369bfc 100644 > > --- a/arch/arm/boot/dts/am33xx.dtsi > > +++ b/arch/arm/boot/dts/am33xx.dtsi > > @@ -62,7 +62,7 @@ > > reg = <0x48200000 0x1000>; > > }; > > > > - gpio1: gpio@44e07000 { > > + gpio0: gpio@44e07000 { > > compatible = "ti,omap4-gpio"; > > ti,hwmods = "gpio1"; > > gpio-controller; > > @@ -74,7 +74,7 @@ > > interrupts = <96>; > > }; > > > > - gpio2: gpio@4804c000 { > > + gpio1: gpio@4804c000 { > > compatible = "ti,omap4-gpio"; > > ti,hwmods = "gpio2"; > > gpio-controller; > > @@ -86,7 +86,7 @@ > > interrupts = <98>; > > }; > > > > - gpio3: gpio@481ac000 { > > + gpio2: gpio@481ac000 { > > compatible = "ti,omap4-gpio"; > > ti,hwmods = "gpio3"; > > gpio-controller; > > @@ -98,7 +98,7 @@ > > interrupts = <32>; > > }; > > > > - gpio4: gpio@481ae000 { > > + gpio3: gpio@481ae000 { > > compatible = "ti,omap4-gpio"; > > ti,hwmods = "gpio4"; > > gpio-controller; > > -- > > 1.7.9.5 > > > > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ ^ permalink raw reply [flat|nested] 25+ messages in thread
