2020-01-08drm/sun4i: drc: Make sure we enforce the clock rateMaxime Ripard
The DRC needs to run at 300MHz to be functional. This was done so far using assigned-clocks in the device tree, but that is easy to forget, and doesn't provide any other guarantee than the rate is going to be roughly the one requested at probe time. Therefore it's pretty fragile, so let's just use the exclusive clock API to enforce it.

2020-01-08drm/exynos: dsi: Fix bridge chain handlingBoris Brezillon
Commit 05193dc38197 ("drm/bridge: Make the bridge chain a double-linked list") patched the bridge chain logic to use a double-linked list instead of a single-linked list. This change induced changes to the Exynos driver which was manually resetting the encoder->bridge element to NULL to control the enable/disable sequence of the bridge chain. During this conversion, 2 bugs were introduced: 1/ list_splice() was used to move chain elements to our own internal chain, but list_splice() does not reset the source list to an empty state, leading to unexpected bridge hook calls when drm_bridge_chain_xxx() helpers were called by the core. Replacing the list_splice() call by list_splice_init() fixes this problem. 2/ drm_bridge_chain_xxx() helpers operate on the bridge->encoder->bridge_chain list, which is now empty. When the helper uses list_for_each_entry_reverse() we end up with no operation done which is not what we want. But that's even worse when the helper uses list_for_each_entry_from(), because in that case we end up in an infinite loop searching for the list head element which is no longer encoder->bridge_chain but exynos_dsi->bridge_chain. To address that problem we stop using the bridge chain helpers and call the hooks directly.

2020-01-07drm/amd/display: Reduce HDMI pixel encoding if max clock is exceededThomas Anderson
For high-res (8K) or HFR (4K120) displays, using uncompressed pixel formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the "interesting" modes would be disabled, leaving only low-res or low framerate modes. This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS clock is exceeded. Verified that 8K30 and 4K120 are now available and working with a Samsung Q900R over an HDMI 2.0b link from a Radeon 5700.

But if there's only one VF being used, guest driver should be able to dump some HW info such as clks, temperature,etc. To solve this, now after onevf mode is enabled, host driver will notify guest. If it's onevf mode, guest will do smu hw_init and skip some steps in normal smu hw_init flow because host driver has already done it for smu. With this fix, guest app can talk with smu and dump hw information from smu. v2: refine the logic for pm_enabled.Skip hw_init by not changing pm_enabled. v3: refine is_support_sw_smu and fix some indentation issue.
