Generate DRM/MSM headers on the fly during kernel build. This removes a
need to push register changes to Mesa with the following manual
synchronization step. Existing headers will be removed in the following
commits (split away to ease reviews).

Parity calculation is necessary for VSC SDP implementation. Therefore
create new files dp_utils.c and dp_utils.h and move the parity
calculating functions here. This ensures that they are usable by SDP
programming in both dp_catalog.c and dp_audio.c
Changes in v3:
- Change ordering of the header byte macros
Changes in v2:
- Create new files dp_utils.c and dp_utils.h
- Move the parity calculation to these new files instead of
having them in dp_catalog.c and dp_catalog.h

CDM block comes with its own set of registers and operations
which can be done. In-line with other hardware blocks, this
change adds the dpu_hw_cdm abstraction for the CDM block.
changes in v4:
- used FIELD_PREP() for dpu_hw_cdm_setup_cdwn() operations
- change to lowercase hex in dpu_hw_cdm_bind_pingpong_blk()
- move disable assignment inside else in dpu_hw_cdm_bind_pingpong_blk()
changes in v3:
- fix commit text from sub-blk to blk for CDM
- fix kbot issue for missing static for dpu_hw_cdm_enable()
- fix kbot issue for incorrect documentation style
- add more documentation for enums and struct in dpu_hw_cdm.h
- drop "enable" parameter from bind_pingpong_blk() as we can
just use PINGPONG_NONE for disable cases
- drop unnecessary bit operation for zero value of cdm_cfg
changes in v2:
- replace bit magic with relevant defines
- use drmm_kzalloc instead of kzalloc/free
- some formatting fixes
- inline _setup_cdm_ops()
- protect bind_pingpong_blk with core_rev check
- drop setup_csc_data() and setup_cdwn() ops as they
are merged into enable()

The msm_drv.c contains generic code intermixed with KMS handling code.
Move all KMS-related code to a separate msm_kms.c file, cleaning up init
code while doing this move. This also prevents msm driver from registering

DPU driver contains code to parse clock items from device tree into
special data struct and then enable/disable/set rate for the clocks
using that data struct. However the DPU driver itself uses only parsing
and enabling/disabling part (the rate setting is used by DP driver).
Move this implementation to the DP driver (which actually uses rate
setting) and replace hand-coded enable/disable/get loops in the DPU
with the respective clk_bulk operations. Put operation is removed
completely because, it is handled using devres instead.
DP implementation is unchanged for now.

MSM DRM driver has support for eDP block present on MSM 8x74/8x84 SoC
families. However since addition back in 2015 this driver received only
generic fixes. No actual devices with these SoCs supported upstream (or
by the community) seem to support eDP panels. Judging from downstream
kernels the eDP was present only on MSM8974 LIQUID or on APQ8084 CDP.
Remove this driver.

phy code is left out, which results in a link failure:
ld: drivers/gpu/drm/msm/hdmi/hdmi_phy.o:(.rodata+0x3f0): undefined reference to `msm_hdmi_phy_8996_cfg'
This was only exposed after it became possible to build
test the driver without the clock interfaces.
Make COMMON_CLK a hard dependency for compile testing,
and simplify it a little based on that.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

dpu_irq.c does some unneeded checks and passes control
to dpu_core_irq.c The simple functions can be defined
in the same file where we use them and the files and
their associated hangers on can be deleted.
Additionally the postinstall hook isn't used even
in dpu_core_irq.c so zap that entire path.
v3: No changes

The functions in dpu_dbg.c aren't used. The two main dump functions
fail after a lookup from dpu_dbg_base.reg_base_list which turns out
to never be populated and once those are removed the rest of the
file doesn't make any sense.
v3: No changes
v2: Moved some unrelated changes to another patch

A2XX has its own very simple MMU.
Added a msm_use_mmu() function because we can't rely on iommu_present to
decide to use MMU or not.

Add trace events to track the progress of a GPU submission
msm_gpu_submit occurs at the beginning of the submissions,
msm_gpu_submit_flush happens when the submission is put on
the ringbuffer and msm_submit_flush_retired is sent when
the operation is retired.
To make it easier to track the operations a unique sequence
number is assigned to each submission and displayed in each
event output so a human or a script can easily associate
the events related to a specific submission.

Add support for the A6XX family of Adreno GPUs. The biggest addition
is the GMU (Graphics Management Unit) which takes over most of the
power management of the GPU itself but in a ironic twist of fate
needs a goodly amount of management itself. Add support for the
A6XX core code, the GMU and the HFI (hardware firmware interface)
queue that the CPU uses to communicate with the GMU.

SDM845 SoC includes the Mobile Display Sub System (MDSS) which is a
top level wrapper consisting of Display Processing Unit (DPU) and
display peripheral modules such as Display Serial Interface (DSI)
and DisplayPort (DP).
MDSS functions essentially as a back-end composition engine. It blends
video and graphic images stored in the frame buffers and scans out the
composed image to a display sink (over DSI/DP).
The following diagram represents hardware blocks for a simple pipeline
(two planes are present on a given crtc which is connected to a DSI
connector):
MDSS
+---------------------------------+
| +-----------------------------+ |
| | DPU | |
| | +--------+ +--------+ | |
| | | SSPP | | SSPP | | |
| | +----+---+ +----+---+ | |
| | | | | |
| | +----v-----------v---+ | |
| | | Layer Mixer (LM) | | |
| | +--------------------+ | |

| | +-----+ +-----+ | |
| +----------------------------+ |
+---------------------------------+
The number of DPU sub-blocks (i.e. SSPPs, LMs, PP blocks and INTFs)
depends on SoC capabilities.
Overview of DPU sub-blocks:
---------------------------
* Source Surface Processor (SSPP):
Refers to any of hardware pipes like ViG, DMA etc. Only ViG pipes are
capable of performing format conversion, scaling and quality improvement
for source surfaces.
* Layer Mixer (LM):
Blend source surfaces together (in requested zorder)
* PingPong (PP):
This block controls frame done interrupt output, EOL and EOF generation,
overflow/underflow control.
* Display interface (INTF):
Timing generator and interface connecting the display peripherals.
DRM components mapping to DPU architecture:
------------------------------------------
PLANEs maps to SSPPs
CRTC maps to LMs
Encoder maps to PPs, INTFs
Data flow setup:
---------------
MDSS hardware can support various data flows (e.g.):
- Dual pipe: Output from two LMs combined to single display.
- Split display: Output from two LMs connected to two separate
interfaces.
The hardware capabilities determine the number of concurrent data paths
possible. Any control path (i.e. pipeline w/i DPU) can be routed to any
of the hardware data paths. A given control path can be triggered,
flushed and controlled independently.
Changes in v3:
- Move msm_media_info.h from uapi to dpu/ subdir
- Remove preclose callback dpu (it's handled in core)
- Fix kbuild warnings with parent_ops
- Remove unused functions from dpu_core_irq
- Rename mdss_phys to mdss
- Rename mdp_phys address space to mdp
- Drop _phys from vbif and regdma binding names
