A simple DRM/KMS driver for the TI LCD Controller found in various
smaller TI parts (AM33xx, OMAPL138, etc). This driver uses the
CMA helpers. Currently only the TFP410 DVI encoder is supported
(tested with beaglebone + DVI cape). There are also various LCD
displays, for which support can be added (as I get hw to test on),
and an external i2c HDMI encoder found on some boards.
The display controller supports a single CRTC. And the encoder+
connector are split out into sub-devices. Depending on which LCD
or external encoder is actually present, the appropriate output
module(s) will be loaded.
v1: original
v2: fix fb refcnting and few other cleanups
v3: get +/- vsync/hsync from timings rather than panel-info, add
option DT max-bandwidth field so driver doesn't attempt to
pick a display mode with too high memory bandwidth, and other
small cleanups
v4: remove some unneeded stuff from panel-info struct, properly
set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs

Device-Tree bindings for tilcdc DRM TFP410 output driver
|
|
|
|
Required properties:
|
|
- compatible: value should be "ti,tilcdc,tfp410".
|
|
- i2c: the phandle for the i2c device to use for DDC
|
|
|
|
Recommended properties:
|
|
- pinctrl-names, pinctrl-0: the pincontrol settings to configure
|
|
muxing properly for pins that connect to TFP410 device
|
|
- powerdn-gpio: the powerdown GPIO, pulled low to power down the
|
|
TFP410 device (for DPMS_OFF)
|
|
|
|
Example:
|
|
|
|
dvicape {
|
|
compatible = "ti,tilcdc,tfp410";
|
|
i2c = <&i2c2>;
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&bone_dvi_cape_dvi_00A1_pins>;
|
|
powerdn-gpio = <&gpio2 31 0>;
|
|
};
