Since the zynqmp pinctrl driver now includes support for the
tri-state registers, ensure that the pins needing output-enable
are correctly configured for SOMs.
Currently, there is an issue with the detection of the MMC for
the SOM kv260, resulting in the following error:
ZynqMP> mmc dev 1
Card did not respond to voltage select! : -110
To address this problem, configure the SDIO pins for output-enable
to enable MMC detection.

And occurs when the the inode precommit handlers is attempt to look
up the inode cluster buffer to attach the inode for writeback.
The trail of logic that I can reconstruct is as follows.
1. the inode is clean when inodegc runs, so it is not
attached to a cluster buffer when precommit runs.
2. #1 implies the inode cluster buffer may be clean and not
pinned by dirty inodes when inodegc runs.
3. #2 implies that the inode cluster buffer can be reclaimed
by memory pressure at any time.
4. The assert failure implies that the cluster buffer was
attached to the transaction, but not marked done. It had
been accessed earlier in the transaction, but not marked
done.
5. #4 implies the cluster buffer has been invalidated (i.e.
marked stale).
6. #5 implies that the inode cluster buffer was instantiated
uninitialised in the transaction in xfs_ifree_cluster(),
which only instantiates the buffers to invalidate them
and never marks them as done.
Given factors 1-3, this issue is highly dependent on timing and
environmental factors. Hence the issue can be very difficult to
reproduce in some situations, but highly reliable in others. Luis
has an environment where it can be reproduced easily by g/531 but,
OTOH, I've reproduced it only once in ~2000 cycles of g/531.
I think the fix is to have xfs_ifree_cluster() set the XBF_DONE flag
on the cluster buffers, even though they may not be initialised. The
reasons why I think this is safe are:
1. A buffer cache lookup hit on a XBF_STALE buffer will
clear the XBF_DONE flag. Hence all future users of the
buffer know they have to re-initialise the contents
before use and mark it done themselves.
2. xfs_trans_binval() sets the XFS_BLI_STALE flag, which
means the buffer remains locked until the journal commit
completes and the buffer is unpinned. Hence once marked
XBF_STALE/XFS_BLI_STALE by xfs_ifree_cluster(), the only
context that can access the freed buffer is the currently
running transaction.
3. #2 implies that future buffer lookups in the currently
running transaction will hit the transaction match code
and not the buffer cache. Hence XBF_STALE and
XFS_BLI_STALE will not be cleared unless the transaction
initialises and logs the buffer with valid contents
again. At which point, the buffer will be marked marked
XBF_DONE again, so having XBF_DONE already set on the
stale buffer is a moot point.
4. #2 also implies that any concurrent access to that
cluster buffer will block waiting on the buffer lock
until the inode cluster has been fully freed and is no
longer an active inode cluster buffer.
5. #4 + #1 means that any future user of the disk range of
that buffer will always see the range of disk blocks
covered by the cluster buffer as not done, and hence must
initialise the contents themselves.
6. Setting XBF_DONE in xfs_ifree_cluster() then means the
unlinked inode precommit code will see a XBF_DONE buffer
from the transaction match as it expects. It can then
attach the stale but newly dirtied inode to the stale
but newly dirtied cluster buffer without unexpected
failures. The stale buffer will then sail through the
journal and do the right thing with the attached stale
inode during unpin.
Hence the fix is just one line of extra code. The explanation of
why we have to set XBF_DONE in xfs_ifree_cluster, OTOH, is long and
complex....

Read 32 bits RX info to a local variable to fix race condition between

Another solution is to get RX tag at first statement, but adopted solution
can save some memory read, and also save 15 bytes binary code.
RX tag, a sequence number, is used to ensure that RX data has been DMA to

Right now they are allocated right after uvc_format, without taking into
consideration their required alignment.
This is working fine because both structures have a field with a

The current code cannot handle two roll-over and provide invalid
timestamps.
Revome all the samples from the circular buffer that are more than two
rollovers old, so the algorithm always provides good timestamps.
Note that we are removing values that are more than one second old,
which means that there is enough distance between the two points that
we use for the interpolation to provide good values.
