drm/amd/display: fix clock sequence logic for DCN32
[Why&How]
The newer commit sequence on DCN32 onwards did not finish clock
optimization sequence since the newer sequence did not end up calling
dc_post_update_surfaces_to_stream() which resets dc->optimized_required.
Call this function before passing control on to the new commit sequence.

drm/amd/display: Don't restrict bpc to 8 bpc
This will let us pass the kms_hdr.bpc_switch IGT
test.
The reason the bpc restriction was required is
historical. At one point in time we were not falling
back to a lower bpc when we didn't have enough
bandwidth for the maximum bpc reported by a display.
This meant that we couldn't enable some high refresh
modes unless we limitted the bpc.
Starting with this patch the issue is fixed:
commit
cbd14ae7ea93 ("drm/amd/display: Fix
incorrectly pruned modes with deep color")
This patch implemented a fallback mechanism if mode
validation failed at the max bpc. This means users
now automatically get all modes that can be supported
by at least 6 bpc. The driver will enable the mode
with the highest possible bpc that is supported by
the display.
v2:
- explain why this is no longer needed (Michel)
- refer to commit that fixed bpc fallback (Michel)

drm/radeon: Fix eDP for single-display iMac11,2
Apple iMac11,2 (mid 2010) also with Radeon HD-4670 that has the same
issue as iMac10,1 (late 2009) where the internal eDP panel stays dark on
driver load. This patch treats iMac11,2 the same as iMac10,1,
so the eDP panel stays active.
Additional steps:
Kernel boot parameter radeon.nomodeset=0 required to keep the eDP

drm/amd/display: Pass proper parent for DM backlight device registration
The parent for the backlight device should be the drm-connector object,
not the PCI device.
Userspace relies on this to be able to detect which backlight class device
to use on hybrid gfx devices where there may be multiple native (raw)
backlight devices registered.
Specifically gnome-settings-daemon expects the parent device to have
an "enabled" sysfs attribute (as drm_connector devices do) and tests
that this returns "enabled" when read.
This aligns the parent of the backlight device with i915, nouveau, radeon.
Note that drivers/gpu/drm/amd/amdgpu/atombios_encoders.c also already
uses the drm_connector as parent, only amdgpu_dm.c used the PCI device
as parent before this change.
Note this is marked as a RFC because I don't have hw to test, so this
has only been compile tested! If someone can test this on actual
hw which hits the changed code path that would be great.

drm/fb-helper: Remove drm_fb_helper_unprepare() from drm_fb_helper_fini()
Move drm_fb_helper_unprepare() from drm_fb_helper_fini() into the
calling fbdev implementation. Avoids a possible stale mutex with
generic fbdev code.
As indicated by its name, drm_fb_helper_prepare() prepares struct
drm_fb_helper before setting up the fbdev support with a call to
drm_fb_helper_init(). In legacy fbdev emulation, this happens next
to each other. If successful, drm_fb_helper_fini() later tear down
the fbdev device and also unprepare via drm_fb_helper_unprepare().
Generic fbdev emulation prepares struct drm_fb_helper immediately
after allocating the instance. It only calls drm_fb_helper_init()
as part of processing a hotplug event. If the hotplug-handling fails,
it runs drm_fb_helper_fini(). This unprepares the fb-helper instance
and the next hotplug event runs on stale data.
Solve this by moving drm_fb_helper_unprepare() from drm_fb_helper_fini()
into the fbdev implementations. Call it right before freeing the
fb-helper instance.

drm/shmem-helper: Fix locking for drm_gem_shmem_get_pages_sgt()
Other functions touching shmem->sgt take the pages lock, so do that here
too. drm_gem_shmem_get_pages() & co take the same lock, so move to the
_locked() variants to avoid recursive locking.
Discovered while auditing locking to write the Rust abstractions.

drm/amd/display: disable SubVP + DRR to prevent underflow
[Why&How]
Temporarily disable SubVP+DRR since Xorg has an architectural limitation
where freesync will not work in a multi monitor configuration. SubVP+DRR
requires that freesync be working.
Whether OS has variable refresh setting enabled or not, the state on
the crtc remains same unless an application requests VRR. Due to this,
there is no way to know whether freesync will actually work or not
while we are on the desktop from the kernel's perspective.
If userspace does not have a limitation with multi-display freesync (for
example wayland), then this feature can be enabled by adding a
dcfeaturemask option to amdgpu on the kernel cmdline like:
amdgpu.dcfeaturemask=0x200

drm/i915: Fix GEN8_MISCCPCTL
Register 0x9424 is not replicated on any platform, so it shouldn't be
declared with REG_MCR(). Declaring it with _MMIO() is basically
duplicate of the GEN7 version, so just remove the GEN8 and change all
the callers to use the right functions.
Old versions of the gen8 bspec page used to contain a table with MCR
registers, apparently implying 0x9400 - 0x94ff registers were
replicated. However that table went away and there is no information
related to the ranges for gen8 anymore. Moreover the current behavior of
the driver wouldn't do anything special for 0x9424 since there is no
equivalent table in intel_gt_mcr.c: the driver would just fallback to
intel_uncore_{read,write}(). Therefore, do not care about the possible
special case for gen8 and just use the register as non-MCR for all the
platforms.
One place doing read + write is also converted to intel_uncore_rmw().

drm/i915/pvc: Annotate two more workaround/tuning registers as MCR
XEHPC_LNCFMISCCFGREG0 and XEHPC_L3SCRUB are both in MCR register ranges
on PVC (with HALFBSLICE and L3BANK replication respectively), so they
should be explicitly declared as MCR registers and use MCR-aware
workaround handlers.
The workarounds/tuning settings should still be applied properly on PVC
even without the MCR annotation, but readback verification on
CONFIG_DRM_I915_DEBUG_GEM builds could potentitally give false positive
"workaround lost on load" warnings on parts fused such that a unicast
read targets a terminated register instance.

drm/i915/bios: set default backlight controller index
With backlight controller set to -1 in intel_panel_init_alloc() to
distinguish uninitialized values, and controller later being set only if
it's present in VBT, we can end up with -1 for the controller:
[drm:intel_bios_init_panel [i915]] VBT backlight PWM modulation
frequency 200 Hz, active high, min brightness 0, level 255,
controller
4294967295
There's no harm if it happens on platforms that ignore controller due to
only one backlight controller being present, like on VLV above, but play
it safe.

drm/i915: Pick the backlight controller based on VBT on ICP+
Use the second backlight controller on ICP+ if the VBT asks
us to do so.
On pre-MTP we also check the chicken bit to make sure the
pins have been correctly muxed by the firmware.

drm/i915: Populate encoder->devdata for DSI on icl+
We now have some eDP+DSI dual panel systems floating around
where the DSI panel is the secondary LFP and thus needs to
consult "panel type 2" in VBT in order to locate all the
other panel type dependant stuff correctly.
To that end we need to pass in the devdata to
intel_bios_init_panel_late(), otherwise it'll just assume
we want the primary panel type. So let's try to just populate
the vbt.ports[] stuff and encoder->devdata for icl+ DSI
panels as well.
We can't do this on older platforms as there we risk a DSI
port aliasing with a HDMI/DP port, which is a totally legal
thing as the DSI ports live in their own little parallel
universe.
