Add support for the DSS controller on TI's AM625 SoC in the tidss driver. The AM625 DSS supports 2 video planes connecting to 2 video ports. The first plane is a full plane supporting all the features, while the 2nd plane is a "lite" plane without scaling support. The first video port in AM625 DSS internally provides DPI output to 2 OLDI transmitters. Each OLDI TX outputs 4 differential lanes of video output and 1 of clock output. This patch does not automatically enable the OLDI features of AM625 yet. That support for OLDI will be added subsequently. The second video port outputs DPI data directly out of the SoC. It has 24 data lines and can support a maximum of RGB888 output bus format. Signed-off-by:

The DSS controller on TI's AM625 SoC is an update from that on TI's AM65X SoC. The former has an additional OLDI TX on its first video port that helps output cloned video or WUXGA (1920x1200@60fps) resolution video output over a dual-link mode to reduce the required OLDI clock output. The second video port is same from AM65x DSS and it outputs DPI video data. It can support 2K resolutions @ 60fps, independently. Add the new controller's compatible and update descriptions.

The debug print parameters were swapped in the output and they were printed as decimal values, both the hardware address and the value. Update the debug print to print the parameters in correct order, and use hexadecimal print for both address and value.

The driver only supports OLED controllers that have a native DRM_FORMAT_C1 pixel format and that is why it has harcoded a division of the width by 8. But the driver might be extended to support devices that have a different pixel format. So it's better to use the struct drm_format_info helpers to compute the size of the buffer, used to store the pixels in native format. Signed-off-by:

The resolutions for these panels are fixed and defined in the Device Tree, so there's no point to allocate the buffers on each plane update and that can just be done once. Let's do the allocation and free on the encoder enable and disable helpers since that's where others initialization and teardown operations are done. Signed-off-by:

The driver only supports OLED controllers that have a page height of 8 but there are devices that have different page heights. So it is better to not hardcode this value and instead have it as a per controller data value. Signed-off-by:

A default resolution in the ssd130x driver isn't set to an arbitrary 96x16 anymore. Instead is set to a width and height that's controller dependent. The datasheets for the chips describes the following display resolutions: - SH1106: 132 x 64 Dot Matrix OLED/PLED - SSD1305: 132 x 64 Dot Matrix OLED/PLED - SSD1306: 128 x 64 Dot Matrix OLED/PLED - SSD1307: 128 x 39 Dot Matrix OLED/PLED - SSD1309: 128 x 64 Dot Matrix OLED/PLED Update DT schema to reflect what the driver does and make its users aware.

Currently the driver hardcodes the default values to 96x16 pixels but this default resolution depends on the controller. The datasheets for the chips describes the following display controller resolutions: - SH1106: 132 x 64 Dot Matrix OLED/PLED - SSD1305: 132 x 64 Dot Matrix OLED/PLED - SSD1306: 128 x 64 Dot Matrix OLED/PLED - SSD1307: 128 x 39 Dot Matrix OLED/PLED - SSD1309: 128 x 64 Dot Matrix OLED/PLED Add this information to the devices' info structures, and use it set as a default if not defined in DT rather than hardcoding to an arbitrary value.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert the omap drm driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
