Perform a mechanical translation of rd88f6281-setup.c into DT. Since
the hardware differs between the A0 and A1 stepping, two dts files are
used, and a .dtsi file for the common parts. The A0 part does not have
a "wan" port on the switch and uses PHY address 10 to address the
switch. The A1 part does have the "wan" port and uses address 0.

This commit adds the necessary Device Tree informations to enable
audio support on the Armada 370 DB platform. In details it:
* Instantiates the CS42L51 audio codec on the I2C0 bus, and
configures this bus with the appropriate pin-muxing configuration.
* Enables the I2S audio controller, and configures it with the
appropriate pin-muxing configuration.
* Through hog pins, ensures that the other pins possibly used for I2S
are muxed with another function than I2S.

Pull devicetree fixes from Rob Herring:
"Fix booting on PPC boards. Changes to of_match_node matching caused
the serial port on some PPC boards to stop working. Reverted the
change and reimplement to split matching between new style compatible
only matching and fallback to old matching algorithm"
* tag 'dt-fixes-for-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
of: search the best compatible match first in __of_match_node()
Revert "OF: base: match each node compatible against all given matches first"
|
|
Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.
To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.
Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

Pull irq update from Thomas Gleixner:
"Fix from the urgent branch: a trivial oneliner adding the missing
Kconfig dependency curing build failures which have been discovered by
several build robots.
The update in the irq-core branch provides a new function in the
irq/devres code, which is a prerequisite for driver developers to get
rid of boilerplate code all over the place.
Not a bugfix, but it has zero impact on the current kernel due to the
lack of users. It's simpler to provide the infrastructure to
interested parties via your tree than fulfilling the wishlist of
driver maintainers on which particular commit or tag this should be
based on"

Pull twi tracing fixes from Steven Rostedt:
"Two urgent fixes in the tracing utility.
The first is a fix for the way the ring buffer stores timestamps.
After a restructure of the code was done, the ring buffer timestamp
logic missed the fact that the first event on a sub buffer is to have
a zero delta, as the full timestamp is stored on the sub buffer
itself. But because the delta was not cleared to zero, the timestamp
for that event will be calculated as the real timestamp + the delta
from the last timestamp. This can skew the timestamps of the events
and have them say they happened when they didn't really happen.
That's bad.
The second fix is for modifying the function graph caller site. When
the stop machine was removed from updating the function tracing code,
it missed updating the function graph call site location. It is still
modified as if it is being done via stop machine. But it's not. This
can lead to a GPF and kernel crash if the function graph call site
happens to lie between cache lines and one CPU is executing it while
another CPU is doing the update. It would be a very hard condition to
hit, but the result is severe enough to have it fixed ASAP"

For non compressed extents, iterate_extent_inodes() gives us offsets
that take into account the data offset from the file extent items, while
for compressed extents it doesn't. Therefore we have to adjust them before
placing them in a send clone instruction. Not doing this adjustment leads to
the receiving end requesting for a wrong a file range to the clone ioctl,
which results in different file content from the one in the original send
root.

Because the offload mechanism can fall back to a standard transfer,
having two seperate initialization states is unfortunate. Let's just
have one state which does things consistently. This fixes a bug where
some preparation was missing when the fallback happened. And it makes
the code much easier to follow. To implement this, we put the check
if offload is possible at the top of the offload setup function.

A user was running into errors from an NFS export of a subvolume that had a
default subvol set. When we mount a default subvol we will use d_obtain_alias()
to find an existing dentry for the subvolume in the case that the root subvol
has already been mounted, or a dummy one is allocated in the case that the root
subvol has not already been mounted. This allows us to connect the dentry later
on if we wander into the path. However if we don't ever wander into the path we
will keep DCACHE_DISCONNECTED set for a long time, which angers NFS. It doesn't
appear to cause any problems but it is annoying nonetheless, so simply unset
DCACHE_DISCONNECTED in the get_default_root case and switch btrfs_lookup() to
use d_materialise_unique() instead which will make everything play nicely
together and reconnect stuff if we wander into the defaul subvol path from a
different way. With this patch I'm no longer getting the NFS errors when
exporting a volume that has been mounted with a default subvol set. Thanks,

Currently, the only mount option for max_inline that has any effect is
max_inline=0. Any other value that is supplied to max_inline will be
adjusted to a minimum of 4k. Since max_inline has an effective maximum
of ~3900 bytes due to page size limitations, the current behaviour
only has meaning for max_inline=0.
This patch will allow the the max_inline mount option to accept non-zero
values as indicated in the documentation.

The reason is that we get to call cond_resched_lock(&head_ref->lock) while
still holding @delayed_refs->lock.
So it's different with __btrfs_run_delayed_refs(), where we do drop-acquire
dance before and after actually processing delayed refs.
Here we don't drop the lock, others are not able to add new delayed refs to
head_ref, so cond_resched_lock(&head_ref->lock) is not necessary here.

This reverts commit 105353145eafb3ea919f5cdeb652a9d8f270228e.
Stephen Chivers reported this is broken as we will get a match
entry '.type = "serial"' instead of the '.compatible = "ns16550"'
in the following scenario:
serial0: serial@4500 {
compatible = "fsl,ns16550", "ns16550";
}
struct of_device_id of_platform_serial_table[] = {
{ .compatible = "ns8250", .data = (void *)PORT_8250, },
{ .compatible = "ns16450", .data = (void *)PORT_16450, },
{ .compatible = "ns16550a", .data = (void *)PORT_16550A, },
{ .compatible = "ns16550", .data = (void *)PORT_16550, },
{ .compatible = "ns16750", .data = (void *)PORT_16750, },
{ .compatible = "ns16850", .data = (void *)PORT_16850, },
...
{ .type = "serial", .data = (void *)PORT_UNKNOWN, },
{ /* end of list */ },
};
So just revert this patch, we will use another implementation to find
the best compatible match in a follow-on patch.
