Introduce support for Qualcomm new video acceleration hardware i.e.
iris, used for video stream decoding.

Iris is a multi pipe based hardware that offloads video stream decoding
from the application processor (AP). It supports H.264 decoding.
The AP communicates with hardware through a well defined protocol,
called as host firmware interface (HFI), which provides fine-grained
and asynchronous control over individual hardware features.

This driver implements upgraded HFI gen2 to communicate with firmware.
It supports SM8550 which is based out of HFI gen 2. It also supports
SM8250 which is based out of HFI gen1.

This driver comes with below capabilities:
- V4L2 complaint video driver with M2M and STREAMING capability.
- Supports H264 decoder.

This driver comes with below features:
- Centralized resource management.
- Centralized management of core and instance states.
- Defines platform specific capabilities and features. As a results, it
  provides a single point of control to enable/disable a given feature
  depending on specific platform capabilities.
- Handles various video recommended sequences, like DRC, Drain, Seek,
  EOS.
- Implements asynchronous communication with hardware to achieve better
  experience in low latency usecases.
- Output and capture planes are controlled independently. Thereby
  providing a way to reconfigure individual plane.
- Native hardware support of LAST flag which is mandatory to align with
  port reconfiguration and DRAIN sequence as per V4L guidelines.

Changes since v3:
- Fixed the style issues with dt binding (Krzysztof)
- Pushed  the patch to add maintainers to end of the series (Krzysztof,
  Dmitry)
- Moved the resource initialization next to probe in iris_probe.c and
  squashed the patch of probe and resource initialization (Krzysztof)
- Removed error prints from probe function (Krzysztof)
- Defined bit fields used for register read/write with macros for better
  context (Bryan)
- Converted if/else to switch/case wherever applicable (Bryan)
- Removed defensive NULL checks wherever not required (Bryan, Krzysztof)
- Removed core->state checks except for below scenarios (Bryan)
  - When reverse thread (firmware) can move the state of the core to
    error state.
  - When client can force close the driver and there are still pending
    firmware responses to be read from shared queues (msg and dbg)
  - For PM operations, since its a delayed autosuspend work and sys
    error handler from the reverse thread can move the state to core
    deinit state anytime.
- Acquiring core->lock only for below scenarios (Bryan)
  - Writing to registers.
  - Reading/Writing from/to shared queues.
  - Traversing the instance list of core.
  - To protect the core->state when it can changed by reverse thread.
- Acquiring inst->lock only for below scenario which is needed (Bryan)
  - Serializing the forward and reverse thread
  - To protect the inst structure where the values can be modified by
    firmware.
- Removed usage of core->power_enabled (Krzysztof, Bryan)
- Removed usage of mutex_is_locked  (Krzysztof, Bryan)
- Use C structure for instance caps (Dmitry)
- Split the ctrl ops patch by keeping only the defines, struct and caps
  needed to intialize the ctrl handler and to implement s/g_ctrl
  (Dmitry)
- Removed the instance state checks to allow v4l2-ctl, relying on
  standard vb2 checks instead. (Hans)
- Converted APIs to void wherever applicable except for below (Bryan)
  - iris_hfi_gen2_handle_session_error and
    iris_hfi_gen2_handle_session_property cannot be converted to void
    even though they always return 0.
    Because these are two of the handlers invoked from 
    iris_hfi_gen2_handle_session_response and are of
    iris_hfi_gen2_inst_hfi_range struct type, where same prototype is
    followed for all handlers and return type of all handers should be
    'int'.
    And we cannot have a switch case/if else to handle these
    responses from firmware because we need to parse the responses in a
    particular sequence.
    That's why we opted for this handler based design instead of
    introducing multiple for loop with code duplication.
- Fixed issues reported by kernel bot.
- Fixed v4l2 compliance issue reported with "-s" options based on the
  inputs from Hans.
- Addressed all other review comments and made some code improvements.

Changes since v2:
- introduced support for HFI gen1.
- deprecated Encoder and HEVC, VP9 codecs.
- removed custom vb2 mem ops and used standard framework instead.
- added support for mmap streaming mode.
- migrated all the buffer APIs to mem2mem helper functions.
- registered iris buffer with vb2 framework.
- migrated to clk_bulk, reset_bulk and icc_bulk APIs.
- used pm_domain_attach/detach_list APIs.
- migrated to read/writel and other available helpers for register
  access instead of custom wrappers.
- added documentation for various structures.
- addressed many other review comments from v2.

Note: A harmless onetime error log "Lucid PLL latch failed. Output may
be unstable!" is seen during bootup.  It doesn't impact any video
usecase and is currently under discussion.

Static tools like checkpatch, smatch, dt_binding_check, sparse and
Coccinelle run successfully with this driver.

This driver is tested with v4l2-ctl[1] and Gstreamer[2].

You send the patches with b4, so why do you strip the link to previous

directly whom you call out in your log as having given and received 
action on previous review comments.

i.e. you should email me, Dmitry, Krzysztof, Neil, Nicholas and Hans.
