Introduced subnodes sensor, fan and peci with properties. Signed-off-by: Constantine Shulyupin <const@xxxxxxxxxxxxx> --- 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 diff --git a/Documentation/devicetree/bindings/hwmon/nct7802.txt b/Documentation/devicetree/bindings/hwmon/nct7802.txt new file mode 100644 index 0000000..88ee599 --- /dev/null +++ b/Documentation/devicetree/bindings/hwmon/nct7802.txt @@ -0,0 +1,66 @@ +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 { + reg = <0>; + compatible = "nuvoton,nct7802-thermistor"; + }; + sensor@2 { + reg = <2>; + compatible = "nuvoton,nct7802-thermal-diode"; + }; + fan@0 { + reg = <0>; + compatible = "nuvoton,nct7802-fan-pwm"; + }; + fan@1 { + reg = <1>; + compatible = "nuvoton,nct7802-fan-dc"; + invert; + open-drain; + }; + peci@0 { + reg = <0>; + compatible = "nuvoton,nct7802-peci"; + }; +}; -- 1.9.1 -- 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
