Unify the plane disabling during state readout by pulling the code into
a new helper intel_plane_disable_noatomic(). We'll also read out the
state of all planes, so that we know which planes really need to be
diabled.
Additonally we change the plane<->pipe mapping sanitation to work by
simply disabling the offending planes instead of entire pipes. And
we do it before we otherwise sanitize the crtcs, which means we don't
have to worry about misassigned planes during crtc sanitation anymore.

Add a .get_hw_state() method for planes, returning true or false
depending on whether the plane is enabled. Use it to rewrite the
plane enabled/disabled asserts in platform agnostic fashion.
We do lose the pre-gen4 plane<->pipe mapping checks, but since we're
supposed sanitize that anyway it doesn't really matter.
v2: Reoder patches to not depend on enum old_plane_id
Just call assert_plane_disabled() from assert_planes_disabled()
v3: Deal with disabled power wells in .get_hw_state()
v4: Rebase due skl primary plane code removal

The devm_regulator_get_optional function, unlike it was assumed in the
commit a1c55bccf600 ("drm/panel: lvds: Add support for the power-supply
property"), is actually returning an error pointer with -ENODEV instead of
NULL when there's no regulator to find.
Make sure we handle that case properly.

drm/tegra: Changes for v4.16-rc1
The bulk of these changes are preparation work and addition of support
for Tegra186. Currently only HDMI output (the primary output on Jetson
TX2) is supported, but the hardware is also capable of doing DSI and
DisplayPort.
Tegra DRM now also uses the atomic commit helpers instead of the open-
coded variant that was only doing half its job. As a bit of a byproduct
of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos
property support.
Along the way there are also a few patches to clean up a few things and
fix minor issues.

It was only checking the divider when determing the closest match if
it could not match the requested rate exactly.
For a projector connected to an Olimex A20-OLinuXino-LIME using HDMI
with a native resolution of 1280x800 and pixel clock of 83.5 MHz, this
resulted in 1280x800 mode not being available and the following in dmesg
when the kernel is booted with drm.debug=0x3e:
[drm:drm_mode_debug_printmodeline] Modeline 37:"1280x800" 60 83500 1280 1352 1480 1680 800 810 816 831 0x48 0x5

It is possible that if there is no exact rate match and
"rounded = clk_hw_round_rate(parent, ideal)" gives high enough values
(e.g. if rounded is 2 * ideal) that the condition
"abs(rate - rounded / i) < abs(rate - best_parent / best_div)" is never
met and best_parent is never set. This results in req->rate and
req->best_parent_rate being assigned 0.
To avoid this, we set best_parent to the first calculated rate if it is
unset. The sun4i_tmds_calc_divider function already has a similar check.

When we retire a signaled fence, we free the dependency tree. However,
we skip clearing the list so that if we then try to adjust the priority
of the signaled fence, we may walk the list of freed dependencies.

Geminilake requires the 3D driver to select whether barriers are
intended for compute shaders, or tessellation control shaders, by
whacking a "Barrier Mode" bit in SLICE_COMMON_ECO_CHICKEN1 when
switching pipelines. Failure to do this properly can result in GPU
hangs.
Unfortunately, this means it needs to switch mid-batch, so only
userspace can properly set it. To facilitate this, the kernel needs
to whitelist the register.
The workarounds page currently tags this as applying to Broxton only,
but that doesn't make sense. The documentation for the register it
references says the bit userspace is supposed to toggle only exists on
Geminilake. Empirically, the Mesa patch to toggle this bit appears to
fix intermittent GPU hangs in tessellation control shader barrier tests
on Geminilake; we haven't seen those hangs on Broxton.
v2: Mention WA #0862 in the comment (it doesn't have a name).

The vmw_view_cmd_to_type() function returns vmw_view_max (3) on error.
It's one element beyond the end of the vmw_view_cotables[] table.
My read on this is that it's possible to hit this failure. header->id
comes from vmw_cmd_check() and it's a user controlled number between
1040 and 1225 so we can hit that error. But I don't have the hardware
to test this code.

The SOR0 found on Tegra124 and Tegra210 only supports eDP and LVDS and
therefore has a slightly different clock tree than the SOR1 which does
not support eDP, but HDMI and DP instead.
Commit e1335e2f0cfc ("drm/tegra: sor: Reimplement pad clock") breaks
setups with eDP because the sor->clk_out clock is uninitialized and
therefore setting the parent clock (either the safe clock or either of
the display PLLs) fails, which can cause hangs later on since there is
no clock driving the module.
Fix this by falling back to the module clock for sor->clk_out on those
setups. This guarantees that the module will always be clocked by an
enabled clock and hence prevents those hangs.

Buffer objects need to be either pinned or reserved while a map is active,
that's not the case here, so avoid caching the framebuffer map.
This will cause increasing mapping activity mainly when we don't do
page flipping.
This fixes occasional garbage filled screens when the framebuffer has been
evicted after the map.
Since in-kernel mapping of whole buffer objects is error-prone on 32-bit
architectures and also quite inefficient, we will revisit this later.
