Commit 371f0f085f629 ("ARM: 8426/1: dma-mapping: add missing range check
in dma_mmap()") introduced offset-checking for mappings, which collides
with the fake-offset the drm sets for gems.
Other drm-drivers set this offset to 0 before doing the mapping, so
this looks like the correct way to go for rockchip as well.

When doing the initial setup both the hclk and the aclk need to be
enabled otherwise the board will simply hang. This only occurs when
building the vop driver as a module, when its built-in the initial setup
happens to run before the clock framework shuts of unused clocks
(including the aclk).
While there also switch to doing prepare and enable in one step rather
then separate steps to reduce the amount of code required.

Currently a DDI port may register the DP hotplug handler even though
it's used with HDMI, and the DP HPD handler overrides the encoder
type forcibly to DP. This caused the inconsistency on a machine
connected with a HDMI monitor; upon a hotplug event, the DDI port is
suddenly switched to be handled as a DP although the same monitor is
kept connected, and this leads to the erroneous blank output.
This patch papers over the bug by excluding the previous HDMI encoder
type from this override. This should be fixed more fundamentally,
e.g. by moving the encoder type reset from the HPD or by having
individual encoder objects for HDMI and DP. But since the bug has
been present for a long time (3.17), it's better to have a
quick-n-dirty fix for now, and keep working on a cleaner fix.

The commit [cfb23ed622d0: drm/i915: Allow fuzzy matching in
pipe_config_compare, v2] relaxed the way to compare the pipe
configurations, but one new comparison sneaked in there: it added the
strict has_drrs value check. This causes a regression on many
machines, typically HP laptops with a docking port, where the kernel
spews warnings and eventually fails to set the mode properly like:
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in has_drrs (expected 1, found 0)
------------[ cut here ]------------
WARNING: CPU: 0 PID: 79 at drivers/gpu/drm/i915/intel_display.c:12700 intel_modeset_check_state+0x5aa/0x870 [i915]()

....
This patch just removes the check again for fixing the regression.

There's a few places where we need to access a GPC register from ucode,
but outside of the falcon's io address space. To do this we need to
calculate the offset based on which GPC we're executing on.
This used to be done manually, but we've since found a "base" offset
that can be added by the hardware. To use this, an extra bit needs to
be set in the register address, which is what this macro achieves.
There should be no functional change from this commit.

We have varied reports of swizzling corruption on gen4 desktop, and
confirmation that one at least is triggered by uneven memory banks
(L-shaped memory). The implication is that the swizzling varies between
the paired channels and the remainder of memory on the single channel. As
the object then has unpredictable swizzling (it will vary depending on
exact page allocation and may even change during the object's lifetime as
the pages are replaced), we have to report to userspace that the swizzling
is unknown.
However, some existing userspace is buggy when it meets an unknown
swizzling configuration and so we need to tell another white lie and
mark the swizzling as NONE but report it as UNKNOWN through the extended
get-tiling-ioctl. See

drm/i915: Declare the swizzling unknown for L-shaped configurations
for the previous example where we found that telling the truth to
userspace just ends up in a world of hurt.
Also since we don't truly know what the swizzling is on the pages, we
need to keep them pinned to prevent swapping as the reports also
suggest that some gen4 devices have previously undetected bit17
swizzling.
v2: Combine unknown + quirk patches to prevent userspace ever seeing
unknown swizzling through the normal get-tiling-ioctl. Also use the same
path for the existing uneven bank detection for mobile gen4.

drm/i915: skip modeset if compatible for everyone.
Bring back the i915.fastboot module parameter, disabled by default, due
to backlight regression on Chromebook Pixel 2015.
Apparently the firmware of the Chromebook in question enables the panel
but disables backlight to avoid a brief garbage scanout upon loading the
kernel/module. With fastboot, we leave the backlight untouched, in this
case disabled. The user would have to do a modeset (i.e. not just crank
up the brightness) to enable the backlight.
There is no clean fix readily available, so get back to the drawing
board by reverting.

When diagnosing a unrelated bug for someone on irc, it would seem the hardware can
be brought up by the BIOS with the embedded displayport using the SPLL for spread spectrum.
Right now this is not handled well in i915, and it calculates the crtc needs to
be reprogrammed on the first modeset without SSC, but the SPLL itself was kept
active. Fix this by exposing SPLL as a shared pll that will not be returned
by intel_get_shared_dpll; you have to know it exists to use it.
Changes since v1:
- Create a separate dpll_hw_state.spll for spll, and use
separate pll functions for spll.

With gen < 9 we have had always 50Mhz units as our hw
ratio. With gen >= 9 the hw ratio changed to 16.667Mhz (50/3).
The result was that our gpu frequency tracing started to output
values 3 times larger than expected due to hardcoded scaling
value. Fix this by using Use intel_gpu_freq() when generating Mhz
value from ratio for 'intel_gpu_freq_change' trace event.
