Ilitek ILI9225 display panels
This binding is for display panels using an Ilitek ILI9225 controller in SPI
mode.
Required properties:
- compatible: "ilitek,ili9225-2.2in-176x220"
- rs-gpios: Register select signal
- reset-gpios: Reset pin
The node for this driver must be a child node of a SPI controller, hence
all mandatory properties described in ../spi/spi-bus.txt must be specified.
Optional properties:
- rotation: panel rotation in degrees counter clockwise (0,90,180,270)
Example:
display@0{
compatible = "ilitek,ili9225-2.2in-176x220";
reg = <0>;
spi-max-frequency = <12000000>;
rs-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
rotation = <270>;
};

a drm_device wrong. Doesn't matter, since everyone else gets it wrong
too :-)
- With the fbdev pointer in dev->mode_config we could also make
suspend/resume helpers entirely generic, at least if we add a
dev->mode_config.suspend_state. We could even provide a generic pm_ops
structure with those.
- also rework the drm_framebuffer_funcs->dirty hook wire-up, see above.

* This function checks for platform specific (e.g. DMI based) quirks
* providing info on panel_orientation for systems where this cannot be
* probed from the hard-/firm-ware. To avoid false-positive this function
* takes the panel resolution as argument and checks that against the

* the efifb code. Because of this this function gets compiled into its own
* kernel-module when built as a module.
*
* Returns:
* A DRM_MODE_PANEL_ORIENTATION_* value if there is a quirk for this system,
* or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.
