2017-06-15drm: mxsfb_crtc: Reset the eLCDIF controllerFabio Estevam
According to the eLCDIF initialization steps listed in the MX6SX Reference Manual the eLCDIF block reset is mandatory. Without performing the eLCDIF reset the display shows garbage content when the kernel boots. In earlier tests this issue has not been observed because the bootloader was previously showing a splash screen and the bootloader display driver does properly implement the eLCDIF reset. Add the eLCDIF reset to the driver, so that it can operate correctly independently of the bootloader. Tested on a imx6sx-sdb board.

Sync objects are new toplevel drm object, that contain a pointer to a fence. This fence can be updated via command submission ioctls via drivers. There is also a generic wait obj API modelled on the vulkan wait API (with code modelled on some amdgpu code). These objects can be converted to an opaque fd that can be passes between processes. v2: rename reference/unreference to put/get (Chris) fix leaked reference (David Zhou) drop mutex in favour of cmpxchg (Chris) v3: cleanups from danvet, rebase on drm_fops rename check fd_flags is 0 in ioctls. v4: export find/free, change replace fence to take a syncobj.

2017-06-12drm/vc4: Fix resource leak in 'vc4_get_hang_state_ioctl()' in error handling ↵Christophe JAILLET
path If one 'drm_gem_handle_create()' fails, we leak somes handles and some memory. In order to fix it: - move the 'free(bo_state)' at the end of the function so that it is also called in the eror handling path. This has the side effect to also try to free it if the first 'kcalloc' fails. This is harmless. - add a new label, err_delete_handle, in order to delete already allocated handles in error handling path - remove the now useless 'err' label The way the code is now written will also delete the handles if the 'copy_to_user()' call fails.

2017-06-05drm/bridge/synopsys: dw-hdmi: Use bridge->mode_valid() callbackJose Abreu
Now that we have a callback to check if bridge supports a given mode we can use it in Synopsys Designware HDMI bridge so that we restrict the number of probbed modes to the ones we can actually display. Also, there is no need to use mode_fixup() callback as mode_valid() will handle the mode validation. NOTE: I also had to change the pdata declaration of mode_valid custom callback so that the passed modes are const. I also changed in the platforms I found. Not even compiled it though.

2017-06-02drm/omap: fix tiled buffer stride calculationsTomi Valkeinen
omap_gem uses page alignment for buffer stride. The related calculations are a bit off, though, as byte stride of 4096 gets aligned to 8192, instead of 4096. This patch changes the code to use DIV_ROUND_UP(), which fixes those calculations and makes them more readable.

2017-06-02drm/omap: fix YUV422 rotation with TILERTomi Valkeinen
TILER rotation with YUV422 pixelformats does not work at the moment. All other pixel formats work, because the pixelformat's pixel size is equal to tiler unit size (e.g. XR24's pixel size is 32 bits, and the TILER unit size that has to be used is 32 bits). For YUV422 formats this is not the case, as the TILER unit size has to be 32 bits, but the pixel size is 16 bits. The end result is OCP errors and sync losts. This patch adds the code to adjust the variables for YUV422 formats. We could make the code more generic by passing around the pixel format, rotation type, angle and the tiler unit size, which would allow us to do calculations without special case for YUV422. However, this would make the code more complex, and at least for now this is much more easier to handle with these two special cases for YUV422.

At the moment the dispc driver uses a custom enum for rotation. Change it to use the DRM's DRM_MODE_ROTATE_*. Note that mirroring is at the moment handled as a separate boolean in the dispc driver, so we only use the DRM_MODE_ROTATE_* values. Note, DSS HW uses clockwise rotation, DRM counter-clockwise.
