Christian Lamparter 87d08b11b1 devicetree: add lm90 thermal_zone sensor support
This patch updates the LM90's devicetree definition to
include the #thermal-sensor-cells property as well as
the sensor constants in include/dt-bindings/thermal/lm90.h.

* LM90 series thermometer.
Required node properties:
- compatible: manufacturer and chip name, one of
"adi,adm1032"
"adi,adt7461"
"adi,adt7461a"
"gmt,g781"
"national,lm90"
"national,lm86"

"dallas,max6696"
"onnn,nct1008"
"winbond,w83l771"
"nxp,sa56004"
- reg: I2C bus address of the device
- vcc-supply: vcc regulator for the supply voltage.
Optional properties:
- interrupts: Contains a single interrupt specifier which describes the
LM90 "-ALERT" pin output.
See interrupt-controller/interrupts.txt for the format.
- #thermal-sensor-cells: should be set to 1. See thermal/thermal.txt for
details. See <include/dt-bindings/thermal/lm90.h> for the
definition of the local, remote and 2nd remote sensor index
constants.
Example LM90 node:
temp-sensor {
compatible = "onnn,nct1008";
reg = <0x4c>;
vcc-supply = <&palmas_ldo6_reg>;
interrupt-parent = <&gpio>;
interrupts = <TEGRA_GPIO(O, 4) IRQ_TYPE_LEVEL_LOW>;
#thermal-sensor-cells = <1>;
}
