drm: adv7511: Fix nested sleep when reading EDID
The EDID read code waits for the read completion interrupt to occur
using wait_event_interruptible(). The condition passed to the macro
reads I2C registers. This results in sleeping with the task state set
to TASK_INTERRUPTIBLE, triggering a WARN_ON() introduced in commit

Fix this by reworking the EDID read code. Instead of checking whether
the read is complete through I2C reads, handle the interrupt registers

drm/i915: Export total subslice and EU counts
Setup new I915_GETPARAM ioctl entries for subslice total and

GPGPU commands. This kernel query method is intended to replace
the PCI ID-based tables that userspace drivers currently maintain.
The kernel driver can employ fuse register reads as needed to
ensure the most accurate determination of GT config attributes.
This first became important with Cherryview in which the config
could differ between devices with the same PCI ID.
The kernel detection of these values is device-specific and not
included in this patch. Because zero is not a valid value for any of
these parameters, a value of zero is interpreted as unknown for the
device. Userspace drivers should continue to maintain ID-based tables
for older devices not supported by the new query method.

drm/i915: Add polish to VLV WM shift+mask operations
Wrap the FW register value shift+mask operations into a macro to hide
the ugliness a bit. Also might avoid bugs due to typos.
Also rename all the primary/sprite plane low order bit masks to have the
_VLV suffix, so that we can use the FW_WM_VLV() macro instead of the
FW_WM() macro for them in a consistent manner. Cursor and all the high
order bits are left to use the FW_WM() macro as there's no real
confusion with them.

drm/i915: Don't assume primary & cursor are always on for wm calculation (v4)
Current ILK-style watermark code assumes the primary plane and cursor
plane are always enabled. This assumption, along with the combination
of two independent commits that got merged at the same time, results in
a NULL dereference. The offending commits are:

drm/i915/skl: Update watermarks for Y tiling
The first commit causes us to use the FB from plane->state->fb rather
than the legacy plane->fb, which is updated a bit later in the process.
The second commit includes a change that now triggers watermark
reprogramming on primary plane enable/disable where we didn't have one
before (which wasn't really correct, but we had been getting lucky
because we always calculated as if the primary plane was on).
Together, these two commits cause the watermark calculation to
(properly) see plane->state->fb = NULL when we're in the process of
disabling the primary plane. However the existing watermark code
assumes there's always a primary fb and tries to dereference it to find
out pixel format / bpp information.
The fix is to make ILK-style watermark calculation actually check the
true status of primary & cursor planes and adjust our watermark logic
accordingly.
v2: Update unchecked uses of state->fb for other platforms (pnv, skl,
etc.). Note that this is just a temporary fix. Ultimately the
useful information is going to be computed at check time and stored
right in the state structures so that we don't have to figure this
all out while we're supposed to be programming the watermarks.
(caught by Tvrtko)
v3: Fix a couple copy/paste mistakes in SKL code. (Tvrtko)
v4: Only add FB checks for ILK/SKL codepaths. Older platforms still use
intel_crtc_active() and will shortcircuit out of watermark
calculations before ever trying to dereference the primary plane's
framebuffer.
