6323113b7a drm/i915: Move SKL IPC WA to HAS_IPC()
SKL has IPC but it should not be set according to the WA, so lets
just mark as it don't have it to simply the code and avoid
unnecessary MMIO writes at every call to intel_enable_ipc().

fd847b8e60 drm/i915: Do not modifiy reserved bit in gens that do not have IPC
IPC was only added in SKL+(actually we don't even enable for SKL due
WA) so without this change, driver was writing to a reserved bit.

Also removing the uncessary dev_priv->ipc_enabled = false; as now
gens without IPC will not have IPC enabled.

v2(Rodrigo):
- moved the new handling of WA #0477 to the next patch

6edafc4eb3 drm/i915: Unset reset pch handshake when PCH is not present in one place
Right now RESET_PCH_HANDSHAKE_ENABLE is enabled all the times inside
of intel_power_domains_init_hw() and if PCH is NOP it is unsed in
i915_gem_init_hw().
So making skl_pch_reset_handshake() handle both cases and calling
it for the missing gens in intel_power_domains_init_hw().
Ivybridge have a different register and bits but with the same
objective so moving it too.

v2(Rodrigo):
- handling IVYBRIDGE case inside intel_pch_reset_handshake()

v4(Rodrigo and Ville):
- moving the enable/disable decision to callers

fc3fed5d29 drm/i915: Check fb stride against plane max stride
commit 4e0b83a567 ("drm/i915: Extract per-platform plane->check()
functions") removed the plane max stride check for sprite planes.
I was going to add it back when introducing GTT remapping for the
display, but after further thought it seems better to re-introduce
it separately.

So let's add the max stride check back. And let's do it in a nicer
form than what we had before and do it for all plane types (easy
now that we have the ->max_stride() plane vfunc).

Only sprite planes really need this for now since primary planes
are capable of scanning out the current max fb size we allow, and
cursors have more stringent stride checks elsewhere.

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.

- Unconditionally clear crtc_state->active_planes as well.
- Reword commit message, since this is now a preparation patch for

b2164e4815 drm/i915/execlists: Onion unwind for logical_ring_init() failure
Fix up the error unwind for logical_ring_init() failing by moving the
cleanup into the callers who own the various bits of state during
initialisation, so we don't forget to free the state allocated by the
caller.

8e1cb32d51 drm/i915: Park the GPU on module load
Once we have flushed the first request through the system to both load a
context and record the default state; tell the GPU to park and idle
itself, putting itself immediately (hopefully at least) into a
powersaving state, and allowing ourselves to start from known state
after setting up all our bookkeeping.

b8bdd9cc60 drm/i915/selftests: Live tests emit requests and so require rpm
As we emit requests or touch HW directly for some of the live tests, the
requirement is that we hold the rpm wakeref before doing so. We want a
mix of granularity since we will want to test runtime suspend, so try to
mark up only the critical sections where we need rpm for the live test.

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.

R-Car DU changes for v4.20

The pull request mostly contains updates to the R-Car DU driver, notably
support for interlaced modes on Gen3 hardware, support for the LVDS output on
R8A77980, and a set of miscellaneous bug fixes. There are also two SPDX
conversion patches for the drm shmobile and panel-lvds drivers, as well as an
update to MAINTAINERS to add Kieran Bingham as a co-maintainer for the DU
driver.
