Logical ports are never going to have EDID changes,
they are used for the internal ports on MST monitors.
We cache the EDIDs from these to save time at MST probe.
v2: drop misplace tile property line, meant for other patch.

A tile group is an identifier shared by a single monitor,
DisplayID topology has 8 bytes we can use for this, just
use those for now until something else comes up in the
future. We assign these to an idr and use the idr to
tell userspace what connectors are in the same tile group.
DisplayID v1.3 says the serial number must be unique for
displays from the same manufacturer.
v2:
destroy idr (dvdhrm)
add docbook (danvet)
airlied:- not sure how to make docbook add fns to tile group section.
v3: fix missing unlock.

When we unplug a dp mst branch we unreference the entire tree from
the root towards the leaves. Which is ok, since that's the way the
pointers and so also the refcounts go.
But when we drop the reference we must make sure that we remove the
branches/ports from the lists/pointers before dropping the reference.
Otherwise the get_validated functions will still return it instead
of returning NULL (which indicates a potentially on-going unplug).
The mst branch destroy gets this right for ports: First it deletes
the port from the ports list, then it unrefs. But the ports destroy
function gets it wrong: First it unrefs, then it drops the ref. Which
means a zombie mst branch can still be validate with get_validated_mstb_ref
when it shouldn't.
Fix this.
This should address a backtrace Dave dug out somewhere on unplug:

On MST systems the monitors don't appear when we set the fb up,
but plymouth opens the drm device and holds it open while they
come up, when plymouth finishes and lastclose gets called we
don't do the delayed fb probe, so the monitor never appears on the
console.
Fix this by moving the delayed checking into the mode restore.
v2: Daniel suggested that ->delayed_hotplug is set under
the mode_config mutex, so we should check it under that as
well, while we are in the area.

At least on two MST devices I've tested with, when
they are link training downstream, they are totally
unable to handle aux ch msgs, so they defer like nuts.
I tried 16, it wasn't enough, 32 seems better.
This fixes one Dell 4k monitor and one of the

This patch checks if the process that opens the /dev/kfd device is 32-bit
process. If so, it returns -EPERM and prints a warning message in dmesg.
This is done to prevent 32-bit user processes from using amdkfd, and hence, HSA

Cadence I2C controller has bug wherein it generates invalid read transactions
after timeout in master receiver mode. This driver does not use the HW
timeout and this interrupt is disabled but the feature itself cannot be
disabled. Hence, this patch writes the maximum value (0xFF) to this register.
This is one of the workarounds to this bug and it will not avoid the issue
completely but reduces the chances of error.

According to I2C specification the NACK should be handled as follows:
"When SDA remains HIGH during this ninth clock pulse, this is defined as the Not
Acknowledge signal. The master can then generate either a STOP condition to
abort the transfer, or a repeated START condition to start a new transfer."
[I2C spec Rev. 6, 3.1.6: http://www.nxp.com/documents/user_manual/UM10204.pdf]
Currently the Davinci i2c driver interrupts the transfer on receipt of a
NACK but fails to send a STOP in some situations and so makes the bus
stuck until next I2C IP reset (idle/enable).
For example, the issue will happen during SMBus read transfer which
consists from two i2c messages write command/address and read data:
S Slave Address Wr A Command Code A Sr Slave Address Rd A D1..Dn A P
<--- write -----------------------> <--- read --------------------->
The I2C client device will send NACK if it can't recognize "Command Code"
and it's expected from I2C master to generate STP in this case.
But now, Davinci i2C driver will just exit with -EREMOTEIO and STP will
not be generated.
Hence, fix it by generating Stop condition (STP) always when NACK is received.
This patch fixes Davinci I2C in the same way it was done for OMAP I2C
commit cda2109a26eb ("i2c: omap: query STP always when NACK is received").

Pull devicetree bugfix from Grant Likely:
"One more bug fix for v3.18. I debated whether or not to send you this
merge request because we're at such a late rc. The bug isn't critical
in that there is only one system known to be affected and the patch is
easy to backport. The codepath is used by pretty much every DT based
system, so there is risk a of regression (it /should/ be safe, but
I've been bitten by stuff that should be safe before). I've had it in
linux-next for a week and haven't received any complaints.
I think it probably should just be merged right away rather than
waiting for the merge window and backporting. It does fix a real bug
and the code is theoretically safer after the change. I can't think
of any situation where it would be dangerous to reserve the DT memory
an extra time.
