+Nuvoton NCT7802Y Hardware Monitoring IC
+
+Required node properties:
+
+ - "compatible": must be "nuvoton,nct7802"
+ - "reg": I2C bus address of the device
+ - #address-cells=<1>;
+ - #size-cells=<0>;
+
+Optional subnodes:
+
+Subnode "sensor" properties:
+ - "reg": index in range 0..3
+ - "compatible", allowed values:
+ - "nuvoton,nct7802-thermal-diode"
+ - "nuvoton,nct7802-thermistor"
+ - "nuvoton,nct7802-voltage"
+
+Sensor at address 2 can't be "nuvoton,nct7802-thermal-diode".
+
+Subnode "fan":
+Required properties:
+ - "reg" :index of in range 0 .. 2.
+ - "compatible", allowed values:
+ "nuvoton,nct7802-fan-pwm" :PWM powered fan
+ "nuvoton,nct7802-fan-dc" :direct current powered fan
+Optional boolean properties:
+ - "invert" :inverted polarity
+ - "open-drain" :open-drain output instead push pull
+
+Subnode "peci" properties:
+ - "reg" :index in range 0..1
+ - "compatible", should be "nuvoton,nct7802-peci"
+
+Not defined sensors, fans and PECI modules will be disabled.
+
+Example nct7802 node:
+
+nct7802 {
+ compatible = "nuvoton,nct7802";
+ reg = <0x2a>;
+ #address-cells=<1>;
+ #size-cells=<0>;
+ sensor@0 {

+ };
+ fan@0 {
+ reg = <0>;

+ fan@1 {
+ reg = <1>;
+ compatible = "nuvoton,nct7802-fan-dc";

Introduced subnodes sensor, fan and peci with properties. Signed-off-by: Constantine Shulyupin <const@MakeLinux.com> --- Changed in v6: - Removed previous definition. - Introduced subnodes sensor, fan and peci with properties. Changed in v5: - Fixed typos Changed in v4: - Removed registers initialization by names - Added properties nuvoton,sensor*-type Changed in v3: - Fixed vendor prefix - Added short registers description, full registers description is available at https://www.nuvoton.com/hq/products/cloud-computing/hardware-monitors/desktop-server-series/nct7802y/ Changed in v2: - Removed nct7802,reg-init - Added registers initialization by names Introduced in v1: - nct7802,reg-init --- .../devicetree/bindings/hwmon/nct7802.txt | 66 ++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/nct7802.txt
