a145b5b0e4 drm/i915: Always backoff after a drm_modeset_lock() deadlock 
If drm_modeset_lock() reports a deadlock it sets the ctx->contexted
field and insists that the caller calls drm_modeset_backoff() or else it
generates a WARN on cleanup.

0dac37bf1c drm/komeda: Add irq handling 
1. Added irq_handler/irq_enable/irq_disable to komeda_dev_func, then the
   Komeda-CORE can control the HW irq via these chip function.
2. Install irq and register irq_handler to system by DRM, so once the IRQ
   coming, the handling sequence is:

   komeda_kms_irq_handler(int irq, void *data)
        /* step 1. call into the CHIP to recognize event */
	mdev->funcs->irq_handler(mdev, &evts);

	/* step 2. notify the crtc to handle the events */
	for (i = 0; i < kms->n_crtcs; i++)
		komeda_crtc_handle_event(&kms->crtcs[i], &evts);

v2:
- Move get IRQ number into this change.
- Enable irq before drm_dev_register.

805446c834 drm/i915: Introduce concept of a sub-platform 
Concept of a sub-platform already exist in our code (like ULX and ULT
platform variants and similar),implemented via the macros which check a
list of device ids to determine a match.

With this patch we consolidate device ids checking into a single function
called during early driver load.

A few low bits in the platform mask are reserved for sub-platform
identification and defined as a per-platform namespace.

At the same time it future proofs the platform_mask handling by preparing
the code for easy extending, and tidies the very verbose WARN strings
generated when IS_PLATFORM macros are embedded into a WARN type
statements.

v2: Fixed IS_SUBPLATFORM. Updated commit msg.
v3: Chris was right, there is an ordering problem.

v4:
 * Catch-up with new sub-platforms.
 * Rebase for RUNTIME_INFO.
 * Drop subplatform mask union tricks and convert platform_mask to an
   array for extensibility.

v5:
 * Fix subplatform check.
 * Protect against forgetting to expand subplatform bits.
 * Remove platform enum tallying.
 * Add subplatform to error state. (Chris)
 * Drop macros and just use static inlines.
 * Remove redundant IRONLAKE_M. (Ville)

v6:
 * Split out Ironlake change.
 * Optimize subplatform check.
 * Use __always_inline. (Lucas)
 * Add platform_mask comment. (Paulo)
 * Pass stored runtime info in error capture. (Chris)

v7:
 * Rebased for new AML ULX device id.
 * Bump platform mask array size for EHL.
 * Stop mentioning device ids in intel_device_subplatform_init by using
   the trick of splitting macros i915_pciids.h. (Jani)
 * AML seems to be either a subplatform of KBL or CFL so express it like
   that.

v8:
 * Use one device id table per subplatform. (Jani)

f84d3d37b7 drm: rockchip: introduce rk3066 hdmi 
The RK3066 HDMI TX serves as interface between a LCD Controller and
a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and
one HDMI transmitter PHY. The interface has three (3) 8-bit data channels
which can be configured for a number of bus widths (8/10/12/16/20/24-bit)
and different video formats (RGB, YCbCr).

Features:
HDMI version 1.4a, HDCP revision 1.4 and
DVI version 1.0 compliant transmitter.
Supports DTV resolutions from 480i to 1080i/p HD.
Master I2C interface for a DDC connection.
HDMI TX supports multiple power save modes.
The HDMI TX input can switch between LCDC0 and LCDC1.
(Sound support is not included in this patch)

ee8efa8079 drm/i915: Check domains for userptr on release 
When we return pages to the system, we release control over them and
should defensively return them to the CPU write domain so that we catch
any external writes on reacquiring them (e.g. to transparently
swapout/swapin). While we did this defensive clflushing for ordinary
shmem pages, it was forgotten for userptr. Fortunately, userptr objects
are normally cache coherent and so oblivious to the forgotten domain
tracking.

cde5f7edd5 drm/i915: Avoid using ctx->file_priv during construction 
As we only set ctx->file_priv on registering the GEM context after
construction, it is invalid to try and use it in the middle for setting
various parameters. Indeed, we put the file_priv into struct create_ext
so that we have the right file_private available without having to look
at ctx->file_priv. However, it helps to use it!

d57b39e3ee drm/i915/gvt: Enable async flip on plane surface mmio writes 
According to Intel GFX PRM on 01.org, plane surface address can be updated
synchronously or asynchronously. Synchronous flip will hold plane surface
address update to start of next vsync, which is current implementation.
Asynchronous flip will update the address as soon as possible. Without
async flip, some 3D application could not reach better performance and
the maximum performance is no higher than vsync frequency.

The patch enables the async flip on plane surface address mmio update,
and increment flip count correctly.

With async flip enabled, some 3D applications have significant performance
improvement. i.e. 3DMark Ice Storm has a 300%~400% increment on score.

v2:
Use bit operation definition for flip mode. (zhenyu)

c4128ce7d5 drm/i915: Skip the linear degamma LUT load on ICL+ 
Don't load the linear degamma LUT on ICL. The hardware no longer
has any silly linkages between the CSC enable and degamma LUT
enable so the degamma LUT is only needed when it's actually
enabled.

Also add comments to explain the situation on GLK.

v2: Drop useless parens around 1<<16
v3: Add missing const

c25abff511 drm/i915: Drop the pointless linear legacy LUT load on CHV 
We now bypass the legacy LUT when it's not needed, so
no point in filling it up with a linear LUT.

f65d5528c0 drm/i915: Extract ilk_color_check()

remains using _intel_color_check(). Streamline the logic
into ilk_color_check().

v2: Add some comments explaining we that we don't expose

fbeb4f3622 drm/i915: Extract glk_color_check() 
Unlike the earlier platforms GLK has dedicated degamma and gamma
LUTs. And quite curiously the degamma LUT is actually controlled
via the PLANE_COLOR_CTL CSC enable bit. Hence we must compute
gamma_enable and csc_enable differently to pre-GLK platforms.

1b386cf849 drm/i915: Extract icl_color_check() 
ICL is rather easy when it comes to .color_check() as it
finally provides us with a full color pipeline with
individual knobs for each stage.

We'll also start bypassing each LUT individually when
it is not needed.

3cdd5174cf drm/i915: Extract chv_color_check() 
Since CHV has the CGM unit we require a custom implementation
of .color_check().

This fixes the computation of gamma_enable as previously we
left it enabled even when were using the CGM gamma instead.
Now we turn off the legacy LUT unless it's actually required.

v2: Add some comment explaining the color pipeline (Matt)
