While working on the issue "ALSA: hda: fix jack detection with Realtek

uses pm_runtime_need_not_resume() to avoid calling resume callback, so

The code predates 2005, it should be unnecessary now as PCI core handles
IRQ much better nowadays.
So stop PCI IRQ mangling in suspend/resume callbacks.
Takashi Iwai mentioned that IRQ number can change after S3 on some
really old hardwares. We should use quirks to handle those platforms, as
Both pm_runtime_force_suspend() and pm_runtime_force_resume() have
some implicit checks, so it can make code flow more straightfoward if we
separate runtime and systemd suspend callbacks.
High Definition Audio Specification, 4.5.9.3 Codec Wake From System S3
states that codec can wake the system
Upon system resume, hda_codec_pm_resume() uses hda_codec_force_resume()
to resume the codec. However, pm_runtime_force_resume() won't really
resume the codec because of pm_runtime_need_not_resume() check.
Hence, hda_codec_force_resume() schedules a jackpoll work, which is to

Tegra VI/CSI hardware don't have native 8 lane capture support.
Each CSI port has max 4 lanes only. So for x8 captures, consecutive
ports are ganged up for left half and right half captures on to each
x4 ports with buffer offsets based on source image split width to align
side-by-side.
All ports
Current implementation uses v4l2_ctrl_subscribe_event() and this

So, update driver to handle V4L2_EVENT_SOURCE_CHANGE.

From: Wei Li
This patch is to support Armv8.3 extension for SPE, it adds alignment
field in the Events packet and it supports the Scalable Vector Extension
(SVE) for Operation packet and Events packet with two additions:
- The vector length for SVE operations in the Operation Type packet;
-
Defines macros for operation packet header and formats (support sub
classes for 'other', 'branch', 'load and store', etc). Uses these
macros for operation packet decoding and dumping.

The packet header parsing uses the hard coded values and it uses nested
if-else statements.
To improve the readability, this patch refactors the macros for packet
header format so it removes the hard coded values. Furthermore, based
on the new mask macros it reduces the nested if-else statements
