Allow to read descriptors via raw upiu. This in fact was forbidden just as
a precaution, as ufs-bsg actually enforces which functionality is
supported.

When we had a write descriptor query upiu, we appended the descriptor right
after the bsg request. This was fine as the bsg driver allows to allocate
whatever buffer we needed in its job request.
Still, the proper way to deliver payload, however small (we only write
config descriptors of 144 bytes), is by using the job request payload data
buffer.
So change this ABI now, while ufs-bsg is still new, and nobody is actually
using it.

Resolution: keep HEAD, and delete the ufshcd_set_vccq_rail_unused() call
and corresponding error-handling code.
Clean up loose ends in a follow-up patch.
60f0187031c0 introduced a small power optimization: ignore the vccq load
specified in the UFSHC DT node when said host controller is connected to
specific Flash chips (currently, Samsung and Hynix).
Unfortunately, this optimization breaks UFS on systems where vccq powers
not only the Flash chip, but the host controller as well, such as APQ8098
MEDIABOX or MTP8998:

In my opinion, the rationale for the original patch is questionable. If
neither the UFSHC, nor the Flash chip, require any load from vccq, then
that power rail should simply not be specified at all in the DT.
Working around that fact in the driver is detrimental, as evidenced by the
failure to initialize the host controller on MSM8998.

When a request has its priority changed, we traverse the graph of all of
its signalers to raise their priorities to match (priority inheritance).
If the request has already started executing its payload, we know that
all of its signalers must have signaled and we do not need to process
our list of signalers.

In the PRP0001 case, the compatible string may have additional data
affiliated with the device. When we call device_get_match_data() on
such device, we will get nothing since currently
acpi_device_get_match_data() doesn't respect PRP0001.
To fix the above, try acpi_of_match_device() if there is no ACPI
table in the driver.
Anyway, note that the device is expected to get its own proper
ACPI ID.

Read the HDMI infoframes from the hbuf and unpack them into
the crtc state.
Well, actually just AVI infoframe for now but let's write the
infoframe readout code in a more generic fashion in case we
expand this later.
Note that Daniel was sceptical about the benefit if this and
also concerned about the potential for crappy sdvo encoders not
implementing the hbuf read commands. My (admittedly limited)
experience is that such encoders don't implement even the
get/set hdmi encoding commands and thus would always be treated
as dvi only. Hence I believe this is safe, and also IMO preferable
having quirks to deal with missing readout support. The readout
support is neatly isolated in the sdvo code whereas the quirk
would leak to other parts of the driver (state checker, fastboot,
etc.) thus complicating the lives of other people.

The routine ccwchain_calc_length() is tasked with looking at a
channel program, seeing how many CCWs are chained together by
the presence of the Chain-Command flag, and returning a count
to the caller.
Previously, it also considered a Transfer-in-Channel CCW as being
an appropriate mechanism for chaining. The problem at the time
was that the TIC CCW will almost certainly not go to the next CCW
in memory (because the CC flag would be sufficient), and so
advancing to the next 8 bytes will cause us to read potentially
invalid memory. So that comparison was removed, and the target
of the TIC is processed as a new chain.
This is fine when a TIC goes to a new chain (consider a NOP+TIC to
a channel program that is being redriven), but there is another
scenario where this falls apart. A TIC can be used to "rewind"
a channel program, for example to find a particular record on a
disk with various orientation CCWs. In this case, we DO want to
consider the memory after the TIC since the TIC will be skipped
once the requested criteria is met. This is due to the Status
Modifier presented by the device, though software doesn't need to
operate on it beyond understanding the behavior change of how the
channel program is executed.
So to handle this, we will re-introduce the check for a TIC CCW
but limit it by examining the target of the TIC. If the TIC
doesn't go back into the current chain, then current behavior
applies; we should stop counting CCWs and let the target of the
TIC be handled as a new chain. But, if the TIC DOES go back into
the current chain, then we need to keep looking at the memory after
the TIC for when the channel breaks out of the TIC loop. We can't
use tic_target_chain_exists() because the chain in question hasn't
been built yet, so we will redefine that comparison with some small
functions to make it more readable and to permit refactoring later.

This patch adds extack coverage in vxlan link
create and changelink paths. Introduces a new helper
vxlan_nl2flags to consolidate flag attribute validation.
thanks to Johannes Berg for some tips to construct the
generic vxlan flag extack strings.

Being able to build devlink as a module causes growing pains.
First all drivers had to add a meta dependency to make sure
they are not built in when devlink is built as a module. Now
we are struggling to invoke ethtool compat code reliably.
Make devlink code built-in, users can still not build it at
all but the dynamically loadable module option is removed.

The *i2c and *i2c_8606 are no longer used since this driver was converted
to use regmap helpers. The *chip and *regulator are not really required.
So remove these unused fields.

Set volt_table filed then we can use regulator_list_voltage_table.
Since we have volt_table setting, now we can remove vol_table from
struct pm8607_regulator_info.

This driver uses regulator_get/set_voltage_sel_regmap so it does not use
vsel_shift. Actually, vsel_shift can be calculated by vsel_mask setting.

The CONFIG_ALTERA_EDAC Kconfig symbol always enables the SDRAM EDAC
functionality. On the newer architectures, however, there are cases
where the peripheral EDAC functionality is enabled but SDRAM needs to be
disabled.
Move SDRAM functions so they can be contained inside the conditional
CONFIG. Create new CONFIG option just for SDRAM.

It was reported that some devices report an OPTIMAL TRANSFER LENGTH of
0xFFFF blocks. That looks bogus, especially for a device with a
4096-byte physical block size.
Ignore OPTIMAL TRANSFER LENGTH if it is not a multiple of the device's
reported physical block size.
To make the sanity checking conditionals more readable--and to
facilitate printing warnings--relocate the checking to a helper
function. No functional change aside from the printks.
