Add a modesetting driver for Grain Media GM12U320 based devices (primarily Acer C120 projector, but there may be compatible devices). This is based on the fb driver from Viacheslav Nurmekhamitov: https://github.com/slavrn/gm12u320 This driver uses drm_simple_display_pipe to deal with all the atomic stuff, gem_shmem_helper functions for buffer management and drm_fbdev_generic_setup for fbdev emulation, so that leaves the driver itself with only the actual code for talking to the gm12u320 chip, leading to a nice simple and clean driver. Changes in v2: -Add drm-misc tree to MAINTAINERS -Drop mode_config.preferred_depth = 24 / fix fbdev support Reviewed-by:

After migrating several drivers to the generic fbdev emulation there are no users left of drm_gem_fbdev_fb_create. Delete the function. Noticed that there was no callers while browsing around in the drm_fb* code. The code that referenced the function was removed by: commit 13aff184 ("drm/qxl: remove dead qxl fbdev emulation code") The actual use was removed by: commit 26d4707d ("drm/qxl: use generic fbdev emulation") v2: - Updated changelog based on feedback from Noralf Signed-off-by:

Conversion from YUV to RGB depends on range (limited or full) and encoding (BT.601 or BT.709). Current code doesn't consider this and always uses BT.601 encoding and limited range. Fix this by introducing new CSC matrices, which are selected based on range and encoding parameters. Signed-off-by:

It turns out addition of 0x200 to constant parts (+0.5) is not really necessary. Besides, we can consider that before and fix value in CSC matrix. This simplifies register writes quiet a bit. Signed-off-by:

drm_vblank.h included uapi/drm/drm.h. It turns out this include was not required - delete it. Note: uapi/drm/drm.h is included indirect via drm_file.h, but there are no dependencies in drm_vblank.h so the removal is legit. Signed-off-by:

This attempts to address outstanding review feedback from commit b8a2948f ("drm/panel: simple: Add ability to override typical timing") Specifically: * It was requested that I document (in the structure definition) that the device tree override had no effect if 'struct drm_display_mode' was used in the panel description. I have provided full Doxygen comments for 'struct panel_desc' to accomplish that. * panel_simple_get_fixed_modes() was thought to be a confusing name, so it has been renamed to panel_simple_get_display_modes(). * panel_simple_parse_override_mode() was thought to be better named as panel_simple_parse_panel_timing_node().

Although the DisplayPort spec explicitly calls out the 1.62/2.7/5.4/8.1 link rates, the value of LINK_BW_SET is calculated. The DisplayPort spec says "Main-Link Bandwidth Setting = Value x 0.27Gbps/lane". A bridge that we're looking to upstream uses 6.75Gbps rate (value 0x19) [1], and that precludes it from using these functions. This 6.75Gbps rate is defined in the spec as (credit to Ville for posting this): A MyDP Source device, upon reading the MAX_LINK_RATE register of the downstream DPRX programmed to 19h (which can be the case only for a MyDP-to-Legacy or MyDP-to-DP lane count converter) can program the LINK_BW_SET register (DPCD Address 00100h) to 19h to enable 6.75Gbps/lane." So to avoid failing on legitimate rates in the future, this patch calculates thevalues according to spec instead of restricting these values to one of the DP_LINK_BW_* #defines. No functional change for the well-defined values, but we lose the warning (and return the correct value) for ill-defined bw values. Signed-off-by:
