Since commit fde192511b ("kconfig: remove tristate choice support"),
all choice blocks are now boolean. There is no longer a need to specify
the choice type explicitly.
Most choice blocks already use "prompt". Before the next commit removes
support for the "bool" syntax in choice entries, this commit converts
the remaining "bool" occurences under drivers/usb/.

Some architectures embed boot DTBs in vmlinux. A potential issue for
these architectures is a race condition during parallel builds because
Kbuild descends into arch/*/boot/dts/ twice.
One build thread is initiated by the 'dtbs' target, which is a
prerequisite of the 'all' target in the top-level Makefile:
ifdef CONFIG_OF_EARLY_FLATTREE
all: dtbs
endif
For architectures that support the built-in boot dtb, arch/*/boot/dts/
is visited also during the ordinary directory traversal in order to
build obj-y objects that wrap DTBs.
Since these build threads are unaware of each other, they can run
simultaneously during parallel builds.
This commit introduces a generic build rule to scripts/Makefile.vmlinux
to support embedded boot DTBs in a race-free way. Architectures that
want to use this rule need to select CONFIG_GENERIC_BUILTIN_DTB.
After the migration, Makefiles under arch/*/boot/dts/ will be visited
only once to build only *.dtb files.
This change also aims to unify the CONFIG options used for built-in DTBs
support. Currently, different architectures use different CONFIG options
for the same purposes.
With this commit, the CONFIG options will be unified as follows:
- CONFIG_GENERIC_BUILTIN_DTB
This enables the generic rule for built-in boot DTBs. This will be
renamed to CONFIG_BUILTIN_DTB after all architectures migrate to the
generic rule.
- CONFIG_BUILTIN_DTB_NAME
This specifies the path to the embedded DTB.
(relative to arch/*/boot/dts/)
- CONFIG_BUILTIN_DTB_ALL
If this is enabled, all DTB files compiled under arch/*/boot/dts/ are
embedded into vmlinux. Only used by MIPS.

The 'dsp' node is currently configured for running an audio firmware.
Since the firmware requires that some audio-related IPs be disabled in
Linux, this will clash with the configurations from the imx8 board DTs
(i.e: imx8qm-mek, imx8qxp-mek, etc...), thus making the dsp unusable
(since the firmware won't function properly).
To avoid this issue, configure the 'dsp' node for rproc. This way, users
will be able to use the dsp alongside the board-level audio configuration
as long as the firmware doesn't need the audio IPs.

We are currently seeing unexpected link trainings with several different
eDP panels. These are caused by these panels stating bad link status in
their dpcd registers. This can be observed by doing following test:
1. Boot up without Xe module loaded
2. Load Xe module with PSR disabled:
$ modprobe xe enable_psr=0
3. Read panel link status register
$ dpcd_reg read --offset 0x200e --count=1
0x200e: 00
4. Enable PSR, sleep for 2 seconds and disable PSR again:
$ echo 0x1 > /sys/kernel/debug/dri/0/i915_edp_psr_debug
$ echo "-1" > /sys/kernel/debug/dri/0000:00:02.0/xe_params/enable_psr
$ echo 0x0 > /sys/kernel/debug/dri/0/i915_edp_psr_debug
$ sleep 2
$ cat /sys/kernel/debug/dri/0/i915_edp_psr_status | grep status
$ echo 0x1 > /sys/kernel/debug/dri/0/i915_edp_psr_debug
Source PSR/PanelReplay status: DEEP_SLEEP [0x80310030]
5. Now read panel link status registers again:
$ dpcd_reg read --offset 0x200e --count=1
0x200e: 80
Workaround this by not trusting link status registers after PSR is enabled
until first short pulse interrupt is received.

Currently, even though there is a bit to control FEC enable/disable
individually, the FEC Decode Enable sequence is sent by the SOC only
once TRANS_CONF enable is set. This ties the FEC enabling too tightly
to modeset and therefore cannot be re-issued (in case of failure)
without a modeset.
From PTL, FEC_DECODE_EN sequence can be sent to a DPRX independent
of TRANS_CONF enable. This allows us to re-issue an FEC_DECODE_EN
sequence without a modeset. Hence allowing us to have a retry
mechanism in case the DPRX does not respond with an FEC_ENABLE
within certain amount of time.
