drm_atomic_helper_wait_for_vblanks will go away in the future. The new drm_atomic_helper_setup_commit in 4.15 expects that blocking commits have completed flipping before the commit_tail returns. This must be ensured by calling wait_for_vblanks or wait_for_flip_done, where flip_done might do a less agressive wait, which is fine for imx-drm.

Commit d178e034 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature to dpi code") replaced usage of platform data version with SoC matching to configure DPI VDDS. The SoC match entries were incorrect, they should have matched on the machine name instead of the SoC family. Fix it. The result was observed on OpenPandora with OMAP3530 where the panel only had the Blue channel and Red&Green were missing. It was not observed on GTA04 with DM3730.

I believe the intention of the commit 2c9fc9bf ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions, like omap4460. By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a same way as it would treat omap4430 ES1.x This breaks HDMI audio on OMAP4460 devices (PandaES for example). Correct the match rule so we are not going to get false positive match. Fixes: 2c9fc9bf ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver") Cc: stable@vger.kernel.org # 4.14 Signed-off-by:

Support the "cec" optional clock. The documentation already mentions "cec" optional clock and it is used by several boards, but currently the driver doesn't enable it, thus preventing cec from working on those boards. And even worse: a /dev/cecX device will appear for those boards, but it won't be functioning without configuring this clock. Changes: v4: - Change commit message to stress the importance of this patch v3: - Drop useless braces v2: - Separate ENOENT errors from others - Propagate other errors (especially -EPROBE_DEFER) Signed-off-by:

If the device tree for a board did not specify a cec clock, then adv7511_cec_init would return an error, which would cause adv7511_probe() to fail and thus there is no HDMI output. There is no need to have adv7511_probe() fail if the CEC initialization fails, so just change adv7511_cec_init() to a void function. In addition, adv7511_cec_init() should just return silently if the cec clock isn't found and show a message for any other errors. An otherwise correct cleanup patch from Dan Carpenter turned this broken failure handling into a kernel Oops, so bisection points to commit 7af35b0a ("drm/kirin: Checking for IS_ERR() instead of NULL") rather than 3b1b9750 ("drm: adv7511/33: add HDMI CEC support").

VMIDs 8-16 in Kaveri were reserved for use by the amdkfd driver. Because we removed amdkfd support from radeon, those VMIDs are now used by radeon and are initialized by radeon. This patch removes the function that initialized those VMIDs for amdkfd use. This initialization overridden the radeon initialization and caused GPU faults and GUI crashed.

drm_atomic_helper_setup_commit expects that flipping of previous commits has happened when it is called to set up a new commit. This can be violated by commits where userspace doesn't get a flip completion event to synchronize against i.e. legacy modesets and property changes. The expectation is that those are done by blocking commits, which wait for completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the commit_tail to ensure completion, but the wait for next vblank might not actually happen if the commit didn't change any planes. Make the wait more agressive by also waiting if no planes changed. This is the minimal regression fix for the 4.15 kernel series. Long term drivers should switch away from drm_atomic_helper_wait_for_vblanks and use drm_atomic_helper_wait_for_flip_done instead.
