Add iio_hwmon node to expose the temperature channel on Vybrid as hardware monitor device using the iio_hwmon driver. Signed-off-by: Sanchayan Maity <maitysanchayan@xxxxxxxxx> --- Hello, The first version of the patch was send quite a while ago. https://lkml.org/lkml/2015/9/16/932 Shawn you had requested that hyphen rather than underscore should be used in node name. I looked into that. The iio_hwmon driver calls hwmon_device register_with_groups inside hwmon.c and this http://lxr.free-electrons.com/source/drivers/hwmon/hwmon.c#L103 does not allow hyphen in hwmon name attribute. I was not aware of this but while trying to test the change, the device probe failed with EINVAL. I think we should stick to the existing use of the bindings or we need to change the hwmon code as well along with the existing device tree files and binding documentation. Changes since v1: 1. Expose ADC1 temperature channel as well 2. Move the entry outside of the aips1 bus node Best Regards, Sanchayan Maity. --- arch/arm/boot/dts/vfxxx.dtsi | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/arch/arm/boot/dts/vfxxx.dtsi b/arch/arm/boot/dts/vfxxx.dtsi index a5f07e3..8ed8e47 100644 --- a/arch/arm/boot/dts/vfxxx.dtsi +++ b/arch/arm/boot/dts/vfxxx.dtsi @@ -673,5 +673,10 @@ status = "disabled"; }; }; + + iio_hwmon { + compatible = "iio-hwmon"; + io-channels = <&adc0 16>, <&adc1 16>; + }; }; }; -- 2.7.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
