There are still missing corner cases with cursor interaction and these
fast plane updates on Picasso and Raven2 leading to endless PSTATE
warnings for typical desktop usage depending on the userspace.
This change should be reverted until these issues have been resolved.

[Why]
After clkmgr rework it gets initialized after resource pool.
The clkmgr is used in resource pool init for xgmi path.
That causes driver crash on Vega20 with xgmi due to NULL deref.
[How]
Move xgmi compensation code to dce121_clk_mgr_construct()
That also allows to make dce121_clock_patch_xgmi_ss_info()

The interconnect API provides an interface for consumer drivers to
express their bandwidth needs in the SoC. This data is aggregated
and the on-chip interconnect hardware is configured to the most
appropriate power/performance profile.
Use the API to configure the interconnects and request bandwidth
between DDR and the display hardware (MDP port(s) and rotator
downscaler).
v2: update the path names to be consistent with dpu, handle the NULL

dpu_mdss_destroy() can get called not just from

dpu_mdss_destroy() removes the icc voting by calling
icc_put. This could accidentally remove the voting
done by pm_runtime_enable.
To make the voting balanced add a minimum vote in

The interconnect framework is designed to provide a
standard kernel interface to control the settings of
the interconnects on a SoC.
The interconnect API uses a consumer/provider-based model,
where the providers are the interconnect buses and the
consumers could be various drivers.
MDSS is one of the interconnect consumers which uses the
interconnect APIs to get the path between endpoints and
set its bandwidth requirement for the given interconnected
path.

Add a KMS driver for the Ingenic JZ47xx family of SoCs.
This driver is meant to replace the aging jz4740-fb driver.
This driver does not make use of the simple pipe helper, for the reason
that it will soon be updated to support more advanced features like
multiple planes, IPU integration for colorspace conversion and up/down
scaling, support for DSI displays, and TV-out and HDMI outputs.
Notes:
v2: - Remove custom handling of panel. The panel is now discovered using
the standard API.
- Lots of small tweaks suggested by upstream
v3: - Use devm_drm_dev_init()
- Update compatible strings to -lcd instead of -drm
- Add destroy() callbacks to plane and crtc
- The ingenic,lcd-mode is now read from the bridge's DT node
v4: Remove ingenic,lcd-mode property completely. The various modes are now
deduced from the connector type, the pixel format or the bus flags.
v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers
- Use 32bpp framebuffer instead of 16bpp, as it'll work with both
16-bit and 24-bit panel
- Get rid of drm_format_plane_cpp() which has been dropped upstream
- Avoid using drm_format_info->depth, which is deprecated.

The idea behind keeping the saturation mask local to a context backfired
spectacularly. The premise with the local mask was that we would be more
proactive in attempting to use semaphores after each time the context
idled, and that all new contexts would attempt to use semaphores
ignoring the current state of the system. This turns out to be horribly
optimistic. If the system state is still oversaturated and the existing
workloads have all stopped using semaphores, the new workloads would
attempt to use semaphores and be deprioritised behind real work. The
new contexts would not switch off using semaphores until their initial
batch of low priority work had completed. Given sufficient backload load
of equal user priority, this would completely starve the new work of any
GPU time.
To compensate, remove the local tracking in favour of keeping it as
global state on the engine -- once the system is saturated and
semaphores are disabled, everyone stops attempting to use semaphores
until the system is idle again. One of the reason for preferring local
context tracking was that it worked with virtual engines, so for
switching to global state we could either do a complete check of all the
virtual siblings or simply disable semaphores for those requests. This
takes the simpler approach of disabling semaphores on virtual engines.
The downside is that the decision that the engine is saturated is a
local measure -- we are only checking whether or not this context was
scheduled in a timely fashion, it may be legitimately delayed due to user
priorities. We still have the same dilemma though, that we do not want
to employ the semaphore poll unless it will be used.
v2: Explain why we need to assume the worst wrt virtual engines.

Komeda supports two types of layer split:
- none-scaling split
- scaling split
Since D71 merger only support scaler as input, so for none-scaling split,
the two layer dflow will be output to compiz directly. for scaling_split,
the data flow will be merged by merger firstly, then output the merged
data flow to compiz.
Komeda handles the split in kernel completely to hide the detailed and
complicated split calcualtion to user mode, for user only need to set the
layer_split property to enable/disable it.

Current komeda driver uses three dedicated clks for a specific purpose:
- mclk: main engine clock
- pclk: APB clock
- pipeline->aclk: AXI clock.
But per spec the komeda HW only has three input clks:
- ACLK: used for AXI masters, APB slave and most pipeline processing
- PXCLK for pipeline 0: output pixel clock for pipeline 0
- PXCLK for pipeline 1: output pixel clock for pipeline 1
So one ACLK is enough, no need to split it to three mclk/pclk/axiclk.

To avoid confusion, unify the driver main engine clk name "mclk" to
the spec name "aclk".

Current komeda driver uses three dedicated clks for a specific purpose:
- mclk: main engine clock
- pclk: APB clock
- pipeline->aclk: AXI clock.
But per spec the komeda HW only has three input clks:
- ACLK: used for AXI masters, APB slave and most pipeline processing
- PXCLK for pipeline 0: output pixel clock for pipeline 0
- PXCLK for pipeline 1: output pixel clock for pipeline 1
So one ACLK is enough, no need to split it to three mclk/pclk/axiclk.
drop pclk/pipeline->axiclk. but only keep one mclk in komeda driver.

- Creates the zpos property.
- Implement komeda_crtc_normalize_zpos to replace
drm_atomic_normalize_zpos, reasons as the following:
1. The drm_atomic_normalize_zpos allows to configure same zpos for
different planes, but komeda doesn't support such configuration.
2. For further slave pipline case, Komeda need to calculate the
max_slave_zorder, we will merge such calculation into
komed_crtc_normalize_zpos to save a separated plane_state loop.
3. For feature none-scaling layer_split, which a plane_state will be
assigned to two individual layers(left/right), which requires two
normalize_zpos for this plane, plane_st->normalize_zpos will be used
by left layer, normalize_zpos + 1 for right_layer.

- Y0L2 and P010 are block (tiled) format, Update the kemeda logic to
compatible with such block format.
- Since DRM introduced a general block information to drm_format_info,
the format_caps->tiled_size no long needed, delete it.
- Build some fb utils functions for code sharing.
