In the associated power drivers; e.g. axp20x_ac_power, axp20x_usb_power + axp20x_battery. The internal temperature is the only one that logically belongs to the chip as a whole rather than one of the subfunctions. root@chip:~# sensors axp20x_battery-isa-0000 Adapter: ISA adapter in0: 0.00 V curr1: 0.00 A pmic_temp-isa-0000 Adapter: ISA adapter temp1: +42.5°C axp20x_ac-isa-0000 Adapter: ISA adapter in0: 0.00 V curr1: 0.00 A axp20x_usb-isa-0000 Adapter: ISA adapter in0: 4.93 V (min = +4.00 V) curr1: 330.00 mA (max = +0.00 A) > > Signed-off-by: Jonathan McDowell <noodles@xxxxxxxx> > > --- > > arch/arm/boot/dts/axp209.dtsi | 7 +++++++ > > 1 file changed, 7 insertions(+) > > > > diff --git a/arch/arm/boot/dts/axp209.dtsi b/arch/arm/boot/dts/axp209.dtsi > > index ca240cd6f6c3..469d0f7d5185 100644 > > --- a/arch/arm/boot/dts/axp209.dtsi > > +++ b/arch/arm/boot/dts/axp209.dtsi > > @@ -48,6 +48,13 @@ > > * http://dl.linux-sunxi.org/AXP/AXP209%20Datasheet%20v1.0_cn.pdf > > */ > > > > +/ { > > + pmic-temp { > > + compatible = "iio-hwmon"; > > + io-channels = <&axp_adc 4>; /* Internal temperature */ > > + }; > > +}; > > + > > &axp209 { > > compatible = "x-powers,axp209"; > > interrupt-controller; J. -- /-\ | Synonym: word used when you can't |@/ Debian GNU/Linux Developer | spell the one you want \- |
