Ask device connected on sink pad for link frequency
in order to configure CLK_LANE_REG1 (ui_x4).
If not available, ask for pixel rate information to compute it.
This is needed to deal with compressed format such as JPEG
where number of bits per pixel is unknown: computation of
link frequency from pixel rate is not possible.

The sensor needs the MCLK clock running when it's being probed. On
platforms where the sensor is instantiated from a DT (MMP2) it is going
to happen asynchronously.
Therefore, the current modus operandi, where the bridge driver fiddles
with the sensor power and clock itself is not going to fly. As the comments
wisely note, this doesn't even belong there.
Luckily, the ov7670 driver is already able to control its power and
reset lines, we can just drop the MMP platform glue altogether.
It also requests the clock via the standard clock subsystem. Good -- let's
set up a clock instance so that the sensor can ask us to enable the clock.
Note that this is pretty dumb at the moment: the clock is hardwired to a
particular frequency and parent. It was always the case.

An instance of a sensor on DT-based MMP2 platform is always going to be
created asynchronously.
Let's move the manual device creation away from the core to the Cafe
driver (used on OLPC XO-1, not present in DT) and set up appropriate
async matches: I2C on Cafe, FWNODE on MMP (OLPC XO-1.75).

This accesses the clock registers directly and thus is going to stay in the
way of making the driver devicetree friendly.
No boards seems to actually use this. If it's somehow actually needed it
needs to be done differently.

In the patch refactoring the fw-node, the mt9m111 was broken for all
platform_data based platforms, which were the first aim of this
driver. Only the devicetree platform are still functional, probably
because the testing was done on these.
The result is that -EINVAL is systematically return for such platforms,
what this patch fixes.

SPI memory devices from different manufacturers have widely
different configurations for Status, Control and Configuration
registers. JEDEC 216C defines a new map for these common register
bits and their functions, and describes how the individual bits may
be accessed for a specific device. For the JEDEC 216B compliant
flashes, we can partially deduce Status and Configuration registers
functions by inspecting the 16th DWORD of BFPT. Older flashes that
don't declare the SFDP tables (SPANSION FL512SAIFG1 311QQ063 A ©11
SPANSION) let the software decide how to interact with these registers.
The commit dcb4b22eeaf4 ("spi-nor: s25fl512s supports region locking")
uncovered a probe error for s25fl512s, when the Quad Enable bit CR[1]
was set to one in the bootloader. When this bit is one, only the Write
Status (01h) command with two data byts may be used, the 01h command with
one data byte is not recognized and hence the error when trying to clear
the block protection bits.
Fix the above by using the Write Status (01h) command with two data bytes
when the Quad Enable bit is one.
Backward compatibility should be fine. The newly introduced
spi_nor_spansion_clear_sr_bp() is tightly coupled with the
spansion_quad_enable() function. Both assume that the Write Register
with 16 bits, together with the Read Configuration Register (35h)
instructions are supported.

When transmitting certain PTP frames, e.g. SYNC and DELAY_REQ, the
PTP daemon, e.g. ptp4l, is polling the driver for the frame transmit
hardware timestamp. The polling will most likely timeout if the tx
coalesce is enabled due to the Interrupt-on-Completion (IC) bit is
not set in tx descriptor for those frames.
This patch will ignore the tx coalesce parameter and set the IC bit
when transmitting PTP frames which need to report out the frame
transmit hardware timestamp to user space.

When ADDSUB bit is set, the system time seconds field is calculated as
the complement of the seconds part of the update value.
For example, if 3.000000001 seconds need to be subtracted from the
system time, this field is calculated as
2^32 - 3 = 4294967296 - 3 = 0x100000000 - 3 = 0xFFFFFFFD
Previously, the 0x100000000 is mistakenly written as 100000000.
This is further simplified from
sec = (0x100000000ULL - sec);
to
sec = -sec;

domain_context_mapping_one() is taking device_domain_lock first then
iommu lock, while dmar_insert_one_dev_info() is doing the reverse.
That should be introduced by commit:
7560cc3ca7d9 ("iommu/vt-d: Fix lock inversion between iommu->lock and
device_domain_lock", 2019-05-27)
So far I still cannot figure out how the previous deadlock was
triggered (I cannot find iommu lock taken before calling of
iommu_flush_dev_iotlb()), however I'm pretty sure that that change
should be incomplete at least because it does not fix all the places
so we're still taking the locks in different orders, while reverting
that commit is very clean to me so far that we should always take
device_domain_lock first then the iommu lock.
We can continue to try to find the real culprit mentioned in
7560cc3ca7d9, but for now I think we should revert it to fix current
breakage.

Replace the variable set function from "efivar_entry_set" to
"efivar_entry_set_safe" in efibc panic notifier.
In safe function parameter "block" will set to false
and will call "efivar_entry_set_nonblocking"to set efi variables.
efivar_entry_set_nonblocking is guaranteed to
not block and is suitable for calling from crash/panic handlers.
In UEFI android platform, when warm reset happens,
with this change, efibc will not block the reboot process.
Otherwise, set variable will call queue work and send to other offlined
cpus then cause another panic, finally will cause reboot failure.

In the soc_camera removal, the board specific power callback was
dropped. This at least will remove the power optimization from ezx and
em-x270 pxa based boards.
As to recreate the same level of functionality, make the mt9m111 have a
regulator providing it its power, so that board designers can plug in a
gpio based or ldo regulator, mimicking their former soc_camera power
hook.

devm_gpiod_get never returns NULL; therefore it's not necessary to check
for that. PTR_ERR(NULL) also yields zero, which is confusing to smatch.

PTR_ERR(NULL) yields 0 which is commonly used to denote success. This is
the case here, and PTR_ERR(NULL) is apparently shunned upon. Fix this by
explicitly returning 0 if fwnode == NULL.

Commit c62b96050bee ("media: ov6650: Register with asynchronous
subdevice framework") carelessly requested creation of a video device
node by setting a V4L2_SUBDEV_FL_HAS_DEVNODE flag. The driver is not
ready for that as it doesn't implement proper locking required for
serialization of IOCTLs.
Fix it by dropping the flag assignment.

Pull rdma fixes from Doug Ledford:
"This is probably our last -rc pull request. We don't have anything
else outstanding at the moment anyway, and with the summer months on
us and people taking trips, I expect the next weeks leading up to the
merge window to be pretty calm and sedate.
This has two simple, no brainer fixes for the EFA driver.
Then it has ten not quite so simple fixes for the hfi1 driver. The
problem with them is that they aren't simply one liner typo fixes.
They're still fixes, but they're more complex issues like livelock
under heavy load where the answer was to change work queue usage and
spinlock usage to resolve the problem, or issues with orphaned
requests during certain types of failures like link down which
required some more complex work to fix too. They all look like
legitimate fixes to me, they just aren't small like I wish they were.
Summary:
- 2 minor EFA fixes
- 10 hfi1 fixes related to scaling issues"

CEC adapters and controllers (handlers) are now set up as follows:
1. Allocate CEC adapters: setup of control handlers in next step
requires these adapters to be allocated.
2. Setup of control handlers: This must be done prior to registering
and exposing the adapters to user space to avoid a race condition.
3. Register CEC adapters: make them available to user space.
