|
|
Required properties:
|
|
- compatible: must be "qcom,mdss_qpic"
|
|
- reg: offset and length of the register set for the device.
|
|
- reg-names : names to refer to register sets related to this device
|
|
- interrupts: IRQ line
|
|
- vdd-supply: Phandle for vdd regulator device node.
|
|
- avdd-supply: Phandle for avdd regulator device node.
|
|
- qcom,cs-gpio: Phandle for cs gpio device node.
|
|
- qcom,te-gpio: Phandle for te gpio device node.
