The error-recovery code in drm_gem_fb_begin() is of the same pattern as drm_gem_fb_end(). Implement both of them using an internal helper. No functional changes. v2: * print additional information in error message (Javier) * fix commit description (Javier) Signed-off-by:

Support YUV422 output from the Amlogic Meson SoC VPU to the HDMI controller. Without this YUV422 format out of the HDMI encoder leads to using the dw-hdmi YUV444 to YUV422 color conversion which gives wrong colors and a green line on the left edge of the screen. Signed-off-by:

Split up the connector's mode_valid helper into a simple-pipe and a mode-config helper. The simple-pipe helper tests for display-size limits while the mode-config helper tests for memory-bandwidth limits. Also add the mgag200_ prefix to mga_vga_calculate_mode_bandwidth() and comment on the function's purpose. The memory-bandwidth tests assume that the display uses 4 bytes per pixel. The first models of G200SE-A only had 1.75 MiB of VRAM, which limits these devices to 640x480-32. v2: * note the memory constraints on early G200SE-A Signed-off-by:

Test for a mode's memory requirements in the device-wide mode_valid helper. For simplicify, always assume a 32-bit color format. While some rejected modes would work with less colors, implementing this is probably not worth the effort. Also remove the memory-related test from the connector's mode_valid helper. The test uses the bpp value that users can specify on the kernel's command line. This value is unrelated and the test would belong into atomic_check. Signed-off-by:

Initialization of the I2C adapter was allowed to fail. The mgag200 driver would have continued without DDC support. Had this happened in practice, it would have led to segmentation faults in the connector code. Resolve this problem by failing driver initialization on I2C- related errors. v2: * initialize 'ret' before drm_err() (kernel test robot) Signed-off-by:

DDC operation conflicts with concurrent mode setting. Acquire the driver's I/O lock in get_modes to prevent this. This change should have been part of commit 931e3f3a ("drm/mgag200: Protect concurrent access to I/O registers with lock"), but apparently got lost somewhere. v3: * fix commit message to say 'drm/mgag200' (Jocelyn) Signed-off-by:

Interrupt context can't sleep. Drivers like Panfrost and MSM are taking mutex when job is released, and thus, that code can sleep. This results into "BUG: scheduling while atomic" if locks are contented while job is freed. There is no good reason for releasing scheduler's jobs in IRQ context, hence use normal context to fix the trouble.

Add support for atomic update of gamma lut. With this patch the "Night light" feature of gnome3 is working properly on mgag200. v2: - Add a default linear gamma function - renamed functions with mgag200 prefix - use format's 4cc code instead of bit depth - use better interpolation for 16bits gamma - remove legacy function mga_crtc_load_lut() - can't remove the call to drm_mode_crtc_set_gamma_size() because it doesn't work with userspace. - other small refactors v3: - change mgag200_crtc_set_gamma*() argument to struct drm_format_info *format - fix printk format to %p4cc for 4cc and %zu for size_t - rebased to drm-misc-next.

Don't add a mode for the kernel's command-line parameters from within the DRM client code. Doing so can result in an unusable display. If there's no compatible command-line mode, the client will use one of the connector's preferred modes. All mode creation and validation has to be performed by the connector. When clients run, the connector's fill_modes callback has already processed the kernel parameters and validated each mode before adding it. The connector's mode list does not contain invalid modes. v2: * grammar in commit message (Javier) Signed-off-by:
