SHARP LS037V7DW01 TFT-LCD panel
|
||||
===================================
|
||||
|
||||
Required properties:
|
||||
- compatible: "sharp,ls037v7dw01"
|
||||
|
||||
Optional properties:
|
||||
- label: a symbolic name for the panel
|
||||
- enable-gpios: a GPIO spec for the optional enable pin.
|
||||
This pin is the INI pin as specified in the LS037V7DW01.pdf file.
|
||||
- reset-gpios: a GPIO spec for the optional reset pin.
|
||||
This pin is the RESB pin as specified in the LS037V7DW01.pdf file.
|
||||
- mode-gpios: a GPIO
|
||||
ordered MO, LR, and UD as specified in the LS037V7DW01.pdf file.
|
||||
|
||||
Required nodes:
|
||||
- Video port for DPI input
|
||||
|
||||
This panel can have zero to five GPIOs to configure to change configuration
|
||||
between QVGA and VGA mode and the scan direction. As these pins can be also
|
||||
configured with external pulls, all the GPIOs are considered optional with holes
|
||||
in the array.
|
||||
|
||||
Example
|
||||
-------
|
||||
|
||||
Example when connected to a omap2+ based device:
|
||||
|
||||
lcd0: display {
|
||||
compatible = "sharp,ls037v7dw01";
|
||||
power-supply = <&lcd_3v3>;

|
||||
reset-gpios = <&gpio5 27 GPIO_ACTIVE_HIGH>; /* gpio155, lcd RESB */
|
||||
mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH /* gpio154, lcd MO */
|
||||
&gpio1 2 GPIO_ACTIVE_HIGH /* gpio2, lcd LR */
|
||||
&gpio1 3 GPIO_ACTIVE_HIGH>; /* gpio3, lcd UD */
|
||||
