Commit 29bb45f25ff3 ("regmap-mmio: Use native endianness for

implementation for big endian systems caused by duplicate byte
swapping in both regmap and readl()/writel(). Sadly the fix makes

Pull ARM SoC fixes from Olof Johansson:
"The first real batch of fixes for this release cycle, so there are a
few more than usual.
Most of these are fixes and tweaks to board support (DT bugfixes,
etc). I've also picked up a couple of small cleanups that seemed
innocent enough that there was little reason to wait (const/
__initconst and Kconfig deps).
Quite a bit of the changes on OMAP were due to fixes to no longer
write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but
there were also other fixes.
Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC
fixes on OMAP5, and Nomadik had changes to MMC parameters in DT.
All in all, mostly the usual mix of various fixes"

Commit 29bb45f25ff3 (regmap-mmio: Use native endianness for read/write)
attempted to fix some long standing bugs in the MMIO implementation for
big endian systems caused by duplicate byte swapping in both regmap and
readl()/writel() which affected MIPS systems as when they are in big
endian mode they flip the endianness of all registers in the system, not
just the CPU. MIPS systems had worked around this by declaring regmap
using IPs as little endian which is inaccurate, unfortunately the issue
had not been reported.
Sadly the fix makes things worse rather than better. By changing the
behaviour to match the documentation it caused behaviour changes for
other IPs which broke them and by using the __raw I/O accessors to avoid
the endianness swapping in readl()/writel() it removed some memory
ordering guarantees and could potentially generate unvirtualisable
instructions on some architectures.
Unfortunately sorting out all this mess in any half way sensible fashion
was far too invasive to go in during an -rc cycle so instead let's go
back to the old broken behaviour for v4.5, the better fixes are already
queued for v4.6. This does mean that we keep the broken MIPS DTs for
another release but that seems the least bad way of handling the
situation.

This is needed to properly deallocate port payload
after downstream branch get unplugged.
In order to do this unplugged MST topology should
be preserved, to find first alive port on path to
unplugged MST topology, and send payload deallocation
request to branch device of found port.
For this mstb and port kref's are used in reversed
order to track when port and branch memory could be
freed.
Added additional functions to find appropriate mstb
as described above.

Previous implementation does not handle case below: boot up one MST branch
to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output
of 1st MST, GUID is not created for 2nd MST branch. When downstream port of
2nd MST branch send upstream request, it fails because 2nd MST branch GUID
is not available.
New Implementation: only create GUID for MST branch and save it within Branch.

1. Get edid for all connected MST displays, not only on logical ports,
in the same thread as MST topology detection is done:
There are displays that have branches inside w/o logical ports.
So in case another SST display connected downstream system can
end-up in situation when 3 DOWN requests sent: two for
‘remote i2c read’ and one for ‘enum path resources’, making slots full.
2. Call notification callback in one place in the end of topology discovery/update:
This is done to reduce number of events sent to userspace in case complex
topology discovery is going, adding multiple number of connectors;
3. Remove notification callback call from short pulse interrupt processing function:
This is done in order not to block interrupt processing function, in case any
MST request will be made from it. Notification will be send from topology
discovery/update work item.

Our PBN value overflows the 20 bits integer part of the 20.12
fixed point. We need to use 31.32 fixed point to avoid this.
This happens with display clocks larger than 293122 (at 24 bpp),
which we see with the Sharp (and similar) 4k tiled displays.

max_payload is limited by the space we have in
drm_dp_mst_topology_mgr::vcpi_mask,payload_mask. We need to track

xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use
the PCI master abort bit pattern (~0) to calculate a new PCI address
offset to read/write. The has lead to reproducable crashes when testing
surprise removal during device initialization on a Stratus platform, at
least after commit d5ddcdf4d672 ("xhci: rework xhci extended capability
list parsing functions").
The crash is repeatable on a Stratus platform when injecting hardware
faults to induce xHCI host controller hotplug during driver
initialization. If a PCI read in xhci_find_next_ext_cap returns the
master abort pattern, quirk_usb_handoff_xhci may start using a bogus
ext_cap_offset to start searching more bogus PCI addresses.

changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data
and vb2_thread") broke videobuf2-dvb.
The root cause is that, instead of calling threadio->fnc() for
all types of events except for VB2_BUF_STATE_ERROR, it was calling
it only for VB2_BUF_STATE_DONE.
With that, the DVB thread were never called.

The vb2_thread implementation was made generic and was moved from
videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately
that clearly was never tested since it broke read() causing NULL address
references.
The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb
pointer in various core functions).
The v4l2_buffer no longer exists after moving the code into the core and
it is no longer needed. However, the vb2_thread code passed a pointer to
a vb2_buffer to the core functions were a v4l2_buffer pointer was expected
and vb2_thread expected that the vb2_buffer fields would be filled in
correctly.
This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the
pb pointer is a void pointer, so no type-checking took place.
This patch fixes this problem:
1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use
a NULL pointer here since they don't care about v4l2_buffer anyway.
2) let vb2_core_dqbuf pass back the index of the received buffer. This is
all vb2_thread needs: this index is the index into the q->bufs array
and vb2_thread just gets the vb2_buffer from there.
3) the fileio->b pointer (that originally contained a v4l2_buffer) is
removed altogether since it is no longer needed.
Tested with vivid and the cobalt driver.

The tda1004x was updating the properties cache before locking.
If the device is not locked, the data at the registers are just
random values with no real meaning.
This caused the driver to fail with libdvbv5, as such library
calls GET_PROPERTY from time to time, in order to return the
DVB stats.

xhci driver frees data for all devices, both usb2 and and usb3 the
first time usb_remove_hcd() is called, including td_list and and xhci_ring
structures.
When usb_remove_hcd() is called a second time for the second xhci bus it
will try to dequeue all pending urbs, and touches td_list which is already
freed for that endpoint.

During probe, in the device tree case, the data pointer associated to a
compatible is dereferenced. However, not all the compatibles are
associated to a private data pointer.
The generic-xhci and the xhci-platform don't need them, this patch adds a
test on the data pointer before accessing it, avoiding a kernel crash.

when ip fails to enter sleep mode, register access protection will
be disabled, at the same time if all clocks are disabled, access
register will hang up AHB bus.
the common case causes ip sleep failure is that after all ports
enter U3 but before ip enters sleep mode, a port receives a resume
signal('K'). this will happens when such as clicks mouse to try to
do remote-wakeup to stop system enter suspend.
so stop polling root hubs to avoid access xHCI register on bus
suspend, and restart it when bus resumes.

XHCI_SSIC_PORT_UNUSED quirk was applied to the xHCI host controllers
in some Intel SoC chips. With this quirk applied, SSIC port is set
to "unused" prior to xhci_suspend(). This may cause problem if host
fails to suspend. In this case, the port is set to unused without
host further entering D3, and the port will not be usable anymore.

XHCI_PME_STUCK_QUIRK. These two workarounds actually are different and

Commit abce329c27b3 ("xhci: Workaround to get D3 working in Intel xHCI")
adds a workaround for a limitation of PME storm caused by SSIC port in
some Intel SoCs. This commit only handled one SSIC port, while there
are actually two SSIC ports in the chips. This patch handles both SSIC
ports. Without this fix, users still see PME storm.

This reverts commit e210c422b6fd ("xhci: don't finish a TD if we get a
short transfer event mid TD")
Turns out that most host controllers do not follow the xHCI specs and never
send the second event for the last TRB in the TD if there was a short event
mid-TD.
Returning the URB directly after the first short-transfer event is far
better than never returning the URB. (class drivers usually timeout
after 30sec). For the hosts that do send the second event we will go
back to treating it as misplaced event and print an error message for it.
The origial patch was sent to stable kernels and needs to be reverted from
there as well

There is a WARN_ON() in dev_pm_domain_set() that triggers on attempts
to set the pm_domain pointer for devices with a driver bound.
However, that WARN_ON() triggers on attempts to clear the pointer
too and the test it uses is based on checking the device's
p->knode_driver pointer which still is set when the device bus
type's/driver's ->remove callback has been executed. This
leads to false-positive warnings when bus type code calls
dev_pm_domain_set() to clear the pm_domain pointer after
invoking the driver's ->remove() callback.
To avoid those false-positives, make dev_pm_domain_set() check
if the pointer passed to it is NULL and skip the warning in
that case.
