0aaf29b35f drm/i915: Clean up scaler setup, v2.
On skylake we can switch to a high quality scaler mode when only 1 out
of 2 scalers are used, but on GLK and later bit 28 has a different
meaning. Don't set it, and make clear the distinction between
SKL and later PS values.

Changes since v1:
- Add missing break statement.

6c246b81f9 drm/i915: Replace call to commit_planes_on_crtc with internal update, v2.
drm_atomic_helper_commit_planes_on_crtc calls begin_commit,
then plane_update hooks, then flush_commit. Because we keep our own
visibility tracking through plane_state->visible there's no need to
rely on the atomic hooks for this.

By explicitly writing our own helper, we can update visible planes
as needed, which is useful to make NV12 support work as intended.

Changes since v1:
- Reword commit message. (Matt Roper)
- Rename to intel_update_planes_on_crtc(). (Matt)

f59e9701db drm/i915: Make intel_crtc_disable_planes() use active planes mask.
This will only disable planes we actually had marked as visible in
crtc_state->visible_planes and cleans up intel_crtc_disable_plane()
slightly.

This is also useful for when we start enabling NV12 support for gen11,
in which we will make the separate Y plane visible, but ignore the
Y plane's state.

62ef0dd3cc drm/i915: Unconditionally clear plane visibility, v2.
We need to assume the plane has been visible before, even if no CRTC
is assigned to the plane. This is because when enabling a nv12 plane
on gen11, we will have to enable an extra plane and make it visible
by marking it in crtc_state->active_planes for
intel_update_planes_on_crtc().

Additionally, clear visible flag in intel_plane_atomic_check, in case
we ever hit a bug with visibility. Our code implicitly assumes that
plane_state->visible is only true when crtc and fb are set,
so we will either null deref in intel_fbc_choose_crtc() or
do something bad during the actual commit which cares even more.

Changes since v1:
- Unconditionally clear crtc_state->active_planes as well.
- Reword commit message, since this is now a preparation patch for
  NV12 Y / UV plane linking.

While we may not update new_crtc_state, we may clear active_planes

after. If this is immediately followed by a modeset disable, we may
soon not disable the planes correctly when we start depending on
active_planes.

8fcd86baab drm/i915/guc: Restore preempt-context across S3/S4
Stolen memory is lost across S4 (hibernate) or S3-RST as it is a portion
of ordinary volatile RAM. As we allocate our rings from stolen, this may
include the rings used for our preempt context and their breadcrumb
instructions. In order to allow preemption following hibernation and
loss of stolen memory, we therefore need to repopulate the instructions
inside the lost ring upon resume. To handle both module load and resume,
we simply defer constructing the ring to first use.

27e39d3dd3 drm/amdgpu: fix unknown vram mem type for vega20
vega20 should use umc_info v3_3 instead of v3_1. There are
serveral versions of umc_info for vega series. Compared to
various versions of these structures, vram_info strucure is
unified for vega series. The patch switch to query mem_type
from vram_info structure for all the vega series dGPU.

1f81fbc4ce drm/radeon: change function signature to pass full range
In function ‘radeon_process_i2c_ch’ a comparison of a u8 value against

function to use an `int` instead, which match the type used in caller:
`radeon_atom_hw_i2c_xfer`.

Fix the following warning triggered with W=1:

e884818cc0 drm: add LG eDP panel to quirk database
The N value was computed by kernel driver that based on synchronous clock
mode. But only specific N value (0x8000) would be acceptable for
LG LP140WF6-SPM1 eDP panel which is running at asynchronous clock mode.
With the other N value, Tcon will enter BITS mode and display black screen.
Add this panel into quirk database and give particular N value when
calculate M/N divider.

v2: no update
v3: add lost commit messages back for version 2
v4: send patch to both intel-gfx and dri-devel

53ca2edcf0 drm: Change limited M/N quirk to constant N quirk.
Some DP dongles in particular seem to be fussy about too large
link M/N values. Set specific value for N divider can resolve
this issue per dongle vendor's comment. So configure N as
constant value (0x8000) to instead of reduce M/N formula when
specific DP dongle connected.
