At the error path of the firmware loading error, the driver tries to
release the card object and set NULL to drvdata. This may be referred
badly at the possible PM action, as the driver itself is still bound
and the PM callbacks read the card object.
Instead, we continue the probing as if it were no option set. This is
often a better choice than the forced abort, too.

The filesystem freeze sequence in XFS waits on any background

allocation. This results in a deadlock between freeze and the
associated scanner.
Fix this problem by holding superblock write protection across calls

acquired from the workqueue task context, trylock to avoid a similar
deadlock between freeze and blocking on the write lock.

The DT2815 analog output command is 16 bits wide, consisting of the
12-bit sample value in bits 15 to 4, the channel number in bits 3 to 1,
and a voltage or current selector in bit 0. Both bytes of the 16-bit
command need to be written in turn to a single 8-bit data register.
However, the driver currently only writes the low 8-bits. It is broken
and appears to have always been broken.
Electronic copies of the DT2815 User's Manual seem impossible to find
online, but looking at the source code, a best guess for the sequence
the driver intended to use to write the analog output command is as
follows:
1. Wait for the status register to read 0x00.
2. Write the low byte of the command to the data register.
3. Wait for the status register to read 0x80.
4. Write the high byte of the command to the data register.
Step 4 is missing from the driver. Add step 4 to (hopefully) fix the
driver.
Also add a "FIXME" comment about setting bit 0 of the low byte of the
command. Supposedly, it is used to choose between voltage output and
current output, but the current driver always sets it to 1.

Setting a CAN bitrate of 800kbit/s fails with a bitrate error of 1.3% if the
flexcan module is clocked at 30MHz (CAN_CLK_ROOT). This patch changes the clock
frequency from 30MHz to 40MHz which allows to support all bitrates recommended
by CiA.
The patch sets CAN_CLK_SEL to 80MHz by changing its clock parent from
CLK_PLL3_60M to CLK_PLL3_80M. The post-divider CAN_CLK_PODF is set to /2 by
default which makes 40MHz CAN_CLK_ROOT from its parent CAN_CLK_SEL.
Background:
CAN in Automation document 102 (CiA102) recommends the CAN bitrates 10, 20, 50,
125, 250, 500, 800 and 1000kbit/s.
With the flexcan serial clock at 30MHz (original value) setting some common
bitrates ("ip link set canX type can bitrate <bitrate>") gives the following
results:
requested value / actually set value
5000: bitrate 5000 sample-point 0.708
10000: bitrate 10000 sample-point 0.866
20000: bitrate 20000 sample-point 0.866
40000: bitrate 40000 sample-point 0.866
50000: bitrate 50000 sample-point 0.866
80000: bitrate 80000 sample-point 0.866
100000: bitrate 100000 sample-point 0.866
125000: bitrate 125000 sample-point 0.875
250000: bitrate 250000 sample-point 0.866
400000: bitrate 400000 sample-point 0.866
500000: bitrate 500000 sample-point 0.866
666666: bitrate 666666 sample-point 0.800
800000: bitrate 789473 sample-point 0.789 !!!bitrate error 1.3%
1000000: bitrate 1000000 sample-point 0.733
With the flexcan serial clock at 40MHz (new value) we get this:
5000: no more possible
10000: bitrate 10000 sample-point 0.875
20000: bitrate 20000 sample-point 0.875
40000: bitrate 40000 sample-point 0.850
50000: bitrate 50000 sample-point 0.875
80000: bitrate 80000 sample-point 0.850
100000: bitrate 100000 sample-point 0.875
125000: bitrate 125000 sample-point 0.875

800000: bitrate 800000 sample-point 0.800
1000000: bitrate 1000000 sample-point 0.750
A drawback of the modification is that 5kbit/s is no more supported.
Setting the flexcan serial clock to 60MHz or 80MHz would produce similar
results but with losing even more bitrates at the lower end.
Changing the flexcan serial clock to 40MHz might apply for other SoCs
using the flaxcan module as well (e.g. imx6q/d/s..). But since I don't
have such hardware to test I did not add this to the patch.

AFS directories are retained locally as a structured file, with lookup
being effected by a local search of the file contents. When a modification
(such as mkdir) happens, the dir file content is modified locally rather
than redownloading the directory.
The directory contents are accessed in a number of ways, with a number of
different locks schemes:
(1) Download of contents - dvnode->validate_lock/write in afs_read_dir().
(2) Lookup and readdir - dvnode->validate_lock/read in afs_dir_iterate(),
downgrading from (1) if necessary.
(3) d_revalidate of child dentry - dvnode->validate_lock/read in
afs_do_lookup_one() downgrading from (1) if necessary.
(4) Edit of dir after modification - page locks on individual dir pages.
Unfortunately, because (4) uses different locking scheme to (1) - (3),
nothing protects against the page being scanned whilst the edit is
underway. Even download is not safe as it doesn't lock the pages - relying
instead on the validate_lock to serialise as a whole (the theory being that
directory contents are treated as a block and always downloaded as a
block).
Fix this by write-locking dvnode->validate_lock around the edits. Care
must be taken in the rename case as there may be two different dirs - but
they need not be locked at the same time. In any case, once the lock is
taken, the directory version must be rechecked, and the edit skipped if a
later version has been downloaded by revalidation (there can't have been
any local changes because the VFS holds the inode lock, but there can have
been remote changes).

Fix this by always decoding the second status into the second
status/callback block which wasn't being used if the dirs were the same.
The afs_update_dentry_version() calls that update the directory data
version numbers on the dentries can then unconditionally use the second
status record as this will always reflect the state of the destination dir
(the two records will be identical if the destination dir is the same as
the source dir)

If we receive a status record that has VNOVNODE set in the abort field,
xdr_decode_AFSFetchStatus() and xdr_decode_YFSFetchStatus() don't advance
the XDR pointer, thereby corrupting anything subsequent decodes from the
same block of data.
This has the potential to affect AFS.InlineBulkStatus and
YFS.InlineBulkStatus operation, but probably doesn't since the status
records are extracted as individual blocks of data and the buffer pointer
is reset between blocks.
It does affect YFS.RemoveFile2 operation, corrupting the volsync record -
though that is not currently used.
Other operations abort the entire operation rather than returning an error
inline, in which case there is no decoding to be done.

Cleanup a line over 80 characters by removing an if test that is valid
only for 5 GHz. According to the TODO 5 GHz code should be removed.
- find and remove remaining code valid only for 5 GHz. Most of the obvious
ones have been removed, but things like channel > 14 still exist.

MT7621 has three assigned interrupts for the pcie. This
interrupts should properly being mapped taking into account
which devices are finally connected in which bus according
to link status. So the irq mappings should be as follows
according to link status (three bits indicating which devices
are link up):
* For PCIe Bus 1 slot 0:
- status = 0x2 || status = 0x6 => IRQ = pcie1_irq (24).
- status = 0x4 => IRQ = pcie2_irq (25).
- default => IRQ = pcie0_irq (23).
* For PCIe Bus 2 slot 0:
- status = 0x5 || status = 0x6 => IRQ = pcie2_irq (25).
- default => IRQ = pcie1_irq (24).
* For PCIe Bus 2 slot 1:
- status = 0x5 || status = 0x6 => IRQ = pcie2_irq (25).
- default => IRQ = pcie1_irq (24).
* For PCIe Bus 3 any slot:
- default => IRQ = pcie2_irq (25).
Because of this, the function 'of_irq_parse_and_map_pci' cannot
be used and we need to change device tree information from using
the 'interrupt-map' and 'interrupt-map-mask' properties into an
'interrupts' property to be able to get irq information from the
ports using the 'platform_get_irq' and storing an 'irq-map' into
the pcie driver data node to properly map correct irq using a
new 'mt7621_map_irq' function where this map will be read and the
correct irq returned.
