4a29b70907 [media] vimc: Subdevices as modules
Change the core structure for adding subdevices in the topology.
Instead of calling the specific create function for each subdevice,
inject a child platform_device with the driver's name.
Each type of node in the topology (sensor, capture, debayer, scaler)
will register a platform_driver with the corresponding name through the
component subsystem.
Implementing a new subdevice type doesn't require vimc-core to be altered.

This facilitates future implementation of dynamic entities, where
hotpluging an entity in the topology is just a matter of
registering/unregistering a platform_device in the system.
It also facilitates other implementations of different nodes without
touching the core code and remove the need of a header file for each
type of node.

f1f940490d ASoC: audio-graph-scu-card: support 2nd codec endpoint on DT
audio-graph-scu-card can handle below connection which is mainly
for sound mixing purpose.

	+----------+   +-------+
	| CPU0--+--|-->| Codec |
	|       |  |   +-------+
	| CPU1--+  |
	+----------+

>From OF-graph point of view, it should have
CPU0 <-> Codec, and CPU1 <-> Codec on DT.
But current driver doesn't care about 2nd connection
of Codec, because it is dummy from DPCM point of view.

This patch can care 2nd Codec connection, and it should be
supported from OF-graph point of view.
It still have backward compatibility.

There is a concern as follows:
cras getting blocked for 2 seconds (worst-case 3 seconds)
As I understand, ChromeOS expects resume finishes in 1 seconds.
Video/Audio playing after 3 seconds of resume seems against the spec.
If we really have to make the choice I would choose pop noise instead
of waiting for 3 seconds.

8fe19795da ASoC: nau8825: fix jack type detection issue after resume
Fix the issue that mic type detection error after resume.
The microphone type detection procedure will recognize
testing signal on JKSLV pin, but before the procedure,
JKSLV already had supply voltage, that results in the failure.
Therefore, the patch turns off the power and reset the jack type
configuration before suspend. Then redo the jack detection
procedure after resume.

The patch help to fix the issue as follows:
Google issue 37973093: CTIA/OMTP jack type detection failure after resume
Reported Issue
Chrome OS Version  :  ChromeOS R59-9460.13.0
Type of hardware   :  DVT sample

What steps will reproduce the problem?
(1 Play a music
(2 Insert a headphones
(3 Close laptop lid 3 sec then open it
What is the expected output?
The music is normal in the headphones.
What do you see instead?
Singer voice in the music is not clear.

How frequently does this problem reproduce?
Always

What is the impact to the user, and is there a workaround?
If so, what is it?
Re-insert the headset or close the laptop lid and
then open it again can be repaired.

ab924af9ac [media] media: i2c: ov772x: Force use of SCCB protocol
Commit e789029761 ("i2c: sh_mobile: don't send a stop condition by
default inside transfers") makes the i2c_sh_mobile I2C-adapter emit a
stop/start sequence between messages in a single transfer only when
explicitly requested with I2C_M_STOP.

This breaks the ov772x driver in the SH4 Migo-R board as the Omnivision
sensor uses the I2C-like SCCB protocol that doesn't support repeated
starts:

i2c-sh_mobile i2c-sh_mobile.0: Transfer request timed out
ov772x 0-0021: Product ID error 92:92

Fix it by marking the client as SCCB, forcing the emission of a
stop/start sequence between all messages.
As I2C_M_STOP requires the I2C adapter to support protocol mangling,
ensure that the I2C_FUNC_PROTOCOL_MANGLING functionality is available.

Tested on SH4 Migo-R board, with OV772x now successfully probing

71bb23c707 drm/vgem: Pin our pages for dmabuf exports
When the caller maps their dmabuf and we return an sg_table, the caller
doesn't expect the pages beneath that sg_table to vanish on a whim (i.e.
under mempressure). The contract is that the pages are pinned for the
duration of the mapping (from dma_buf_map_attachment() to
dma_buf_unmap_attachment). To comply, we need to introduce our own
vgem_object.pages_pin_count and elevate it across the mapping. However,
the drm_prime interface we use calls drv->prime_pin on dma_buf_attach
and drv->prime_unpin on dma_buf_detach, which while that does cover the
mapping is much broader than is desired -- but it will do for now.

v2: also hold the pin across prime_vmap/vunmap

7d75f32e09 iwlwifi: pcie: delete the Tx queue timer earlier upon firmware crash
When the firmware crashes, the transmit queues can't make
any progress. This is why we stop the counter that monitor
the transmit queues' activity.
The call that notifies the error to the op_mode may take
a bit of time, so stop the timer of the transmit queues
earlier.

d74a61fc6b iwlwifi: pcie: reduce unwanted noise in the logs
The driver prints "L1 Enabled - LTR Enabled" all the time as dev_info,
which is just useless noise in most cases.  Convert this to
IWL_DEBUG_POWER() so we don't pollute the log unnecessarily but still
can get this info on demand.

4409e72b71 iwlwifi: mvm: print base HW address during init
It's sometimes hard to find out which HW address the iwlwifi device is
using, for instance when reading crouded sniffer logs.  To make it
easier, print out an info level message with the HW address as soon as
we know it.

This new API allows flushing queues based on station ID and TID in A000
devices.  One reason for using this is that tfd_queue_mask is only good
for 32 queues, which is not enough for A000 devices.

6c64447ec5 x86/xen/efi: Initialize only the EFI struct members used by Xen
The current approach, which is the wholesale efi struct initialization from
a 'efi_xen' local template is not robust. Usually if new member is defined
then it is properly initialized in drivers/firmware/efi/efi.c, but not in
arch/x86/xen/efi.c.

The effect is that the Xen initialization clears any fields the generic code
might have set and the Xen code does not know about yet.

I saw this happen a few times, so let's initialize only the EFI struct members
used by Xen and maintain no local duplicate, to avoid such issues in the future.

457ea3f7e9 efi: Process the MEMATTR table only if EFI_MEMMAP is enabled
Otherwise e.g. Xen dom0 on x86_64 EFI platforms crashes.

In theory we can check EFI_PARAVIRT too, however,
EFI_MEMMAP looks more targeted and covers more cases.

a509a248bb iwlwifi: mvm: reset the fw_dump_desc pointer after ASSERT
When we get an ASSERT, the fw_dump_desc pointer points to
iwl_mvm_dump_desc_assert which can't be freed since it is
a global. We still need to NULL'ify the pointer when we
call iwl_mvm_free_fw_dump_desc otherwise we will hit

int iwl_mvm_fw_dbg_collect_desc(struct iwl_mvm *mvm,
                                const struct iwl_mvm_dump_desc *desc,
                                const struct iwl_fw_dbg_trigger_tlv *trigger)
{
<snip>
        if (WARN_ON(mvm->fw_dump_desc))
                iwl_mvm_free_fw_dump_desc(mvm);

91e976777d drm/amd|radeon: Drop drm_vblank_cleanup
Both drivers shut down all crtc beforehand already, which will shut up
any pending vblank (the only thing vblank_cleanup really does is
disable the disable timer). Hence we don't need this here and can
remove it.

assoc_beacon_arrive_time is not being set, which causes the FW to

dcfbd67b4b iwlwifi: add a W/A for a scheduler hardware bug
In case we need to move the scheduler write pointer by
steps of 0x40, 0x80 or 0xc0, the scheduler gets stuck.
This leads to hardware error interrupts with status:
0x5A5A5A5A or alike.

In order to work around this, detect in the transport
layer that we are going to hit this case and tell iwlmvm
to increment the sequence number of the packets. This
allows to keep the requirement that the WiFi sequence
number is in sync with the index in the scheduler Tx queue
and it also allows to avoid the problematic sequence.
This means that from time to time, we will start a queue
from ssn + 1, but that shouldn't be a problem since we
don't switch to new queues for AMPDU now that we have
DQA which allows to keep the same queue while toggling
the AMPDU state.

This bug has been fixed on 9000 devices and up.
