The line time can be programmed according to the number of horizontal
pixels vs effective pixel rate ratio.
v2: improve comment as per Chris Wilson suggestion
v3: incorporate latest changes in specs.
v4: move into wm update routine, also mention that the same routine can
program IPS watermarks. We do not have their enablement code yet, nor
handle the required clock settings at the moment, so this patch won't
program those values for now.

Starting with Haswell, DDI ports can work in FDI mode to support
connectivity with the outputs located on the PCH.
This commit adds support for such connections in the intel_ddi module, and
provides Haswell-specific functionality to make it work.

DDI is introduced starting with Haswell GPU generation. So to simplify its
management in the future, we also add intel_ddi.c to hold all the
DDI-related items.
Buffer translations for DDI links must be initialized prior to enablement.
For FDI and DP, first 9 pairs of values are used to select the connection
parameters. HDMI uses the last pair of values and ignores the first 9
pairs. So we program HDMI values in both cases, which allows HDMI to work
over both FDI and DP-friendly buffers.

On Haswell, only one pipe can work in FDI mode, so this patch prevents
messing with wrong registers when FDI is being used by non-first pipe. And
to prevent this, we also specify that the VGA can only be used on pipe 0
for now in the crtc_mask value.

Prevent bogus asserts on DDI-related paths.
Longer explanation from Eugeni by mail:
"For the asserts there are 3 paths where we hit them:
- in assert_fdi_tx (we don't have the FDI_TX_CTL anymore, backup plan
DDI_FUNC_CTL is used instead)
- in assert_fdi_tx_pll_enabled (we have the combination of iCLKIP and
DDI_FUNC_CTL, plus PORT_CLK_SEL and PIPE_CLK_SEL now to make things
work). We could use an assert here indeed - if we configure port to
use one clock, and pipe to use another, everything hangs. Right now,
we configure all of them in one place only; but yes, when DP code
lands it will get more funky.
- and in ironlake_fdi_pll_enable. I reuse part of this function (to
configure the TU sizes), but as in the 1st case, FDI_TX_CTL is gone
so I just ignore it here."

This attempts to enable all the available power wells during the
initialization.
Those power wells can be enabled in parallel or on-demand, and disabled
when no longer needed, but this is out of scope of this initial
enablement. Proper tracking of who uses which power well will require
a considerable rework of our display handling, so we just leave them all
enabled when the driver is loaded for now.

As suggested by Chris Wilson and Daniel Vetter, this chunk of code can be
simplified with a more simple check.
Also, as noticed by Jesse Barnes, it is worth mentioning that plane is an
enum and num_pipe is an int, so we could be more paranoid here about those
validation checks eventually.

Changelog v3:
- use __u64 instead of pointer in ioctl struct.
The G2D is a 2D graphic accelerator that supports Bit Block Transfer.
This G2D driver is exynos drm specific and supports only G2D(version
4.1) of later Exynos series from Exynos4X12 because supporting DMA.
The G2D is performed by two tasks simply.
1. Configures the rendering parameters, such as foreground color and
coordinates data by setting the drawing context registers.
2. Start the rendering process by setting thre relevant command
registers accordingly.
The G2D version 4.1 supports DMA mode as host interface. User can make
command list to reduce HOST(ARM) loads. The contents of The command list
is setted to relevant registers of G2D by DMA.
The command list is composed Header and command sets and Tail.
- Header: The number of command set(4Bytes)
- Command set: Register offset(4Bytes) + Register data(4Bytes)
- Tail: Pointer of base address of the other command list(4Bytes)
By Tail field, the G2D can process many command lists without halt at
one go.
The G2D has following the rendering pipeline.
--> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling
--> Color Key --> ROP --> Mask Operation --> Alpha Blending -->
Dithering --> FrameBuffer
And supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- window clipping
- rotation
- flip
- 4 operand raster operation(ROP4)
- masking operation
- alpha blending
- color key
- dithering
- etc
User should make the command list to data and registers needed by
operation to use. The Exynos G2D driver only manages the command lists
received from user. Some registers needs memory base address(physical
address) of image. User doesn't know its physical address, so fills the
gem handle of that memory than address to command sets, then G2D driver
converts it to memory base address.
We adds three ioctls and one event for Exynos G2D.
- ioctls
DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version
DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver
DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver
- event

command list to user

All radeon_gem_init() does is initialize the gem objects
list. radeon_device.c does this explicitly. r600+ calls
radeon_gem_init() so the list gets initialized twice. Older
asics don't call it at all and rely on the the init in
radeon_device.c. Just call radeon_gem_init() in radeon_device.c
and remove the explicit calls from all the newer asics.
All asics call radeon_gem_fini() in their fini pathes. That
could possibly be cleaned up too.

This is the initial driver for the Aspeed Technologies chips found in
servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
doesn't support the AST11xx due to lack of hw to test it on, and them requiring
different codepaths.
This driver is intended to be used with xf86-video-modesetting in userspace.
This driver has a slightly different design than other KMS drivers, but
future server chips will probably share similiar setup. As these GPUs commonly
have low video RAM, it doesn't make sense to put the kms console in VRAM
always. This driver places the kms console into system RAM, and does dirty
updates to a copy in video RAM. When userspace sets a new scanout buffer,
it forcefully evicts the video RAM console, and X can create a framebuffer
that can use all of of video RAM.
This driver uses TTM but in a very simple fashion to control the eviction
to system RAM of the console, and multiple servers.
