+Required properties: +- compatible: should be "jdi,lt070me05000" +- power-supply: phandle of the regulator that provides the supply voltage
- IOVCC , power supply for LCM (1.8V)
+- vddp-supply: phandle of the regulator that provides the supply voltage
- Power IC supply (3-5V)
+- dcdc_en-supply: phandle of the regulator that provides the supply voltage
- Power IC supply enable, High active
+- reset-gpio: phandle of gpio for reset line
- This should be 8mA, gpio can be configured using mux and pinctrl.
- XRES, Reset, Low active
+- enable-gpio: phandle of gpio for enable line
- LED_EN, LED backlight enable, High active
These should all be -gpios instead.
will implement in v3
+- vcc-gpio: phandle of regulator/gpio that provides the supply voltage
- VDD, LED power supply (3-5V)
Is it a regulator or gpio?
VDD is LED power supply, but in nexus 7 2nd gen they are using gpio 23 instead of regulator. if we use vcc-supply, not sure we can give the gpio device tree entry to it in nexus 7 dts. Any inputs ?
+Optional properties: +- pwm-gpio: phandle of gpio/pwm
This should use the PWM binding. It may not be a GPIO on some hosts.
pwm-gpio will go to the backlight (pwm). right now it is not used since pwm pm8921 upstream driver is not yet implemented. Shall i remove this pwm-gpio now and the backlight property when pwm pm8921 is implemented?
- pwm backlight control, this should be mapped to the backlight level
- display brightness (0x51)
