drm/edid: add separate drm_edid_connector_add_modes()

The original goal with drm_edid_connector_update() was to have a single
call for updating the connector and adding probed modes, in this order,
but that turned out to be problematic. Drivers that need to update the
connector in the .detect() callback would end up updating the probed
modes as well. Turns out the callback may be called so many times that
the probed mode list fills up without bounds, and this is amplified by
add_alternate_cea_modes() duplicating the CEA modes on every call,
actually running out of memory on some machines.

Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me.

Go back to having separate drm_edid_connector_update() and
drm_edid_connector_add_modes() calls. The former may be called from
.detect(), .force(), or .get_modes(), but the latter only from
.get_modes().

Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update
the probed modes from the EDID property instead of the passed in
EDID. This is mainly to enforce two things:

1) drm_edid_connector_update() must be called before
   drm_edid_connector_add_modes().

   Display info and quirks are needed for parsing the modes, and we
   don't want to call update_display_info() again to ensure the info is
   available, like drm_add_edid_modes() does.

2) The same EDID is used for both updating the connector and adding the
   probed modes.

Fortunately, the change is easy, because no driver has actually adopted
drm_edid_connector_update(). Not even i915, and that's mainly because of
the problem described above.

drm/edid: split HDMI VSDB info and mode parsing

Separate the parsing of display info and modes from the HDMI VSDB. This
is prerequisite work for overall better separation of the two parsing
steps.

The info parsing is about figuring out whether the sink supports HDMI
infoframes. Since they were added in HDMI 1.4, assume the sink supports
HDMI infoframes if it has the HDMI_Video_present bit set (introduced in
HDMI 1.4). For details, see commit f1781e9bb2dd ("drm/edid: Allow HDMI
infoframe without VIC or S3D").

The logic is not exactly the same, but since it was somewhat heuristic
to begin with, assume this is close enough.

- Simplify to only check HDMI_Video_present bit (Ville)
- Drop cea_db_raw_size() helper (Ville)

HSA/HBP/HFP/HSE mode bits in Processor Reference Manuals specify
a naming conversion as 'disable mode bit' due to its bit definition,
0 = Enable and 1 = Disable.

For HSE bit, the i.MX 8M Mini/Nano/Plus Applications Processor
Reference Manual named this bit as 'HseDisableMode' but the bit
definition is quite opposite like
0 = Disables transfer
1 = Enables transfer
which clearly states that HSE is not a disable bit.

HSE is named as per the manual even though it is not a disable
bit however the driver logic for handling HSE is based on the
MIPI_DSI_MODE_VIDEO_HSE flag itself.

GEM buffer object handles to submit to the VPU, the driver resolves
buffer handles, pins physical memory if needed, increments ref count
for each buffer and stores pointers to buffer objects in

The VPU signals job completion with an asynchronous message that

Currently, the driver supports simple scheduling logic
where jobs submitted from user space are immediately pushed
to the VPU device command queues. In the future, it will be

accel/ivpu: Add Intel VPU MMU support

VPU Memory Management Unit is based on ARM MMU-600.
It allows the creation of multiple virtual address spaces for
the device and map noncontinuous host memory (there is no dedicated
memory on the VPU).

Address space is implemented as a struct ivpu_mmu_context, it has an ID,
drm_mm allocator for VPU addresses and struct ivpu_mmu_pgtable that
holds actual 3-level, 4KB page table.
Context with ID 0 (global context) is created upon driver initialization
and it's mainly used for mapping memory required to execute
the firmware.
Contexts with non-zero IDs are user contexts allocated each time
the devices is open()-ed and they map command buffers and other
workload-related memory.
Workloads executing in a given contexts have access only
to the memory mapped in this context.

This patch is has two main files:
  - ivpu_mmu_context.c handles MMU page tables and memory mapping
  - ivpu_mmu.c implements a driver that programs the MMU device

accel/ivpu: Introduce a new DRM driver for Intel VPU

VPU stands for Versatile Processing Unit and it's a CPU-integrated
inference accelerator for Computer Vision and Deep Learning
applications.

The VPU device consist of following components:
  - Buttress - provides CPU to VPU integration, interrupt, frequency and
    power management.
  - Memory Management Unit (based on ARM MMU-600) - translates VPU to
    host DMA addresses, isolates user workloads.
  - RISC based microcontroller - executes firmware that provides job
    execution API for the kernel-mode driver
  - Neural Compute Subsystem (NCS) - does the actual work, provides
    Compute and Copy engines.
  - Network on Chip (NoC) - network fabric connecting all the components

This driver supports VPU IP v2.7 integrated into Intel Meteor Lake
client CPUs (14th generation).

Module sources are at drivers/accel/ivpu and module name is
"intel_vpu.ko".

This patch includes only very besic functionality:
  - module, PCI device and IRQ initialization
  - register definitions and low level register manipulation functions
  - SET/GET_PARAM ioctls
  - power up without firmware

drm/edid: use VIC in AVI infoframe if sink lists it in CTA VDB

Apparently there are HDMI 1.4 compatible displays out there that support
VICs from specs later than CTA-861-D, i.e. VIC > 64, although HDMI 1.4
references CTA-861-D only.

We try to avoid using VICs from the later specs in the AVI infoframes to
avoid upsetting sinks that conform to earlier specs.

However, it seems reasonable to do this when the sink claims it supports
the VIC. With the pre-parsed list of VICs handy, this is now trivial.

drm/bridge: lt9611: properly program the dual host mode

If the bridge is connected using both DSI ports, the driver should use
both of them all the time. Correct programming sequence to always use
dual-port mode if both dsi0 and dsi1 are connected.

drm/arm/komeda: Remove unnecessary include statements for drm_crtc_helper.h

Several source files include drm_crtc_helper.h without needing it or
only to get its transitive include statements; leading to unnecessary
compile-time dependencies.

Drop drm_crtc_helper.h where possible.
