f8fb5729a9 media: staging: rkisp1: rsz: don't ignore set format in bayer mainpath
Fix issue when, in case of raw bayer format in mainpath,
VIDIOC_SUBDEV_S_FMT ioctl didn't have any effect, is wasn't updating the
format of the pad.

There is no crop for mainpath bayer raw data. Remove leftover check in
set_format, since check is already done in crop rkisp1_rsz_set_sink_crop()
function.

Stats entity is using a slightly different bus_info string
"platform: rkisp1" (with a space) instead of "platform:rkisp1" used by
the rest of rkisp1 code.
This causes errors when using v4l2-util tools that uses the bus_info

1b3bb57456 media: hantro: Write quantization table registers in increasing addresses order
Luma and chroma qtables need to be written into two 16-register blocks,
each table consisting of 64 bytes total. The blocks are contiguous and
start at offset 0 for luma and at offset 0x40 for chroma.

The seemingly innocent optimization of writing the two blocks using one
loop causes side effects which result in improper values of quantization
tables being used by the hardware during encoding. Visually this results
in macroblocking artifacts around contrasting edges in encoded images. The
artifacts look like horizontally flipped shadows of the said edges.
Changing the write operations to non-relaxed variant doesn't help.

This patch removes this premature optimization and after this change the
macroblocking artifacts around contrasting edges are gone.

85bdcb7eaa media: hantro: Write the quantization tables in proper order
The quantization tables as defined in the file (luma_q_table,
chroma_q_table) are in fact in linear order. The JPEG file header, which is
not generated by the hardware, but must be programatically created with the
CPU, expects the table in zigzag order. On the other hand, the hardware
doesn't expect neither linear, nor zigzag order. Instead it expects the
quantization tables in vertical groups of four quantization parameters,
and the groups are organized in blocks of two vertically adjacent groups.
On top of that the blocks must be provided to the hardware in this order:
leftmost top block, leftmost bottom block, second leftmost top block,
second leftmost bottom block and so on. So, if this is the quantization
table in linear order:

0x10, 0x0b, 0x0a, 0x10, 0x18, 0x28, 0x33, 0x3d,
0x0c, 0x0c, 0x0e, 0x13, 0x1a, 0x3a, 0x3c, 0x37,
0x0e, 0x0d, 0x10, 0x18, 0x28, 0x39, 0x45, 0x38,
0x0e, 0x11, 0x16, 0x1d, 0x33, 0x57, 0x50, 0x3e,
0x12, 0x16, 0x25, 0x38, 0x44, 0x6d, 0x67, 0x4d,
0x18, 0x23, 0x37, 0x40, 0x51, 0x68, 0x71, 0x5c,
0x31, 0x40, 0x4e, 0x57, 0x67, 0x79, 0x78, 0x65,
0x48, 0x5c, 0x5f, 0x62, 0x70, 0x64, 0x67, 0x63

then the hardware expects this in its consecutive registers:

0x100c0e0e,
0x0b0c0d11,
0x12183148,
0x1623405c,
0x0a0e1016,
0x1013181d,
0x25374e5f,
0x38405762,

and so on.

Consequently, the same area of memory cannot be used both for dumping it
into the JPEG file header and writing its contents to the hardware
registers. Instead, a separate pair of arrays is added for properly
reordered quantization tables, to be read with get_unaligned_be32()
and linearly written to the registers.

The "ctx" parameter is not needed any more for hantro_jpeg_get_qtable().

e34bca49e4 media: hantro: Read be32 words starting at every fourth byte
Since (luma/chroma)_qtable is an array of unsigned char, indexing it
returns consecutive byte locations, but we are supposed to read the arrays
in four-byte words. Consequently, we should be pointing
get_unaligned_be32() at consecutive word locations instead.

3eed7385bf media: staging: media: rkisp1: make links immutable by default
The only places which make sese to allow users to enable or disable
links are:

* between sensors and isp:
So users can select which sensor should be used while streaming

* between isp and the resizers:
              |
              v here
rkisp1_isp:2 -> rkisp1_resizer_mainpath -> rkisp1_mainpath (capture)
            \-> rkisp1_resizer_selfpath -> rkisp1_selfpath (capture)
              ^ here
              |

So users can disable one of the capture paths when unused, to avoid
worring about matching formats.

Make the following links immutable to simplify userspace:

rkisp1_resizer_mainpath -> rkisp1_mainpath
rkisp1_resizer_selfpath -> rkisp1_selfpath
rkisp1_params           -> rkisp1_isp
rkisp1_isp              -> rkisp1_stats

Remove 'fs_func struct' and change indirect calls to direct calls.

The following issues are described in exfat's TODO.
> Create helper function for exfat_set_entry_time () and
> exfat_set_entry_type () because it's sort of ugly to be calling the same functionn directly and other code calling through  the fs_func struc ponters ...

The fs_func struct was used for switching the helper functions of fat16/fat32/exfat.
Now, it has lost the role of switching, just making the code less readable.

In wilc_wlan_handle_txq(), mutex unlock was called without acquiring
it. Also error code for full VMM condition was incorrect as discussed in
[1]. Now used a proper code to indicate VMM is full, for which transfer
to VMM is required again. 'wilc_wlan_handle_txq()' should be called
again if the VMM space was full earlier or otherwise based on
'txq_event' signal.

This reverts commit e878742c83.

Imgu should still keep the capability and flexibility to allow user to
run 2 video pipes, as the user may use the video pipe to capture still
frames with less system load and power than still pipe.

d239aa00fe media: hantro: fix post-processing NULL pointer dereference
The RK3399 variant does not have postproc_regs declared,
this can cause a NULL pointer dereference trying to decode:

[   89.331359] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000

[   89.352804] Call trace:
[   89.353191]  hantro_postproc_disable+0x20/0xe8 [hantro_vpu]
[   89.354056]  hantro_start_prepare_run+0x58/0x68 [hantro_vpu]
[   89.354923]  hantro_h264_dec_prepare_run+0x30/0x6f0 [hantro_vpu]

[   89.356748]  device_run+0xa4/0xb8 [hantro_vpu]

Fix this by adding a NULL check in hantro_postproc_enable/disable.

0443b3f443 staging: axis-fifo: replace spinlock with mutex
Following the device's documentation guidance, reading a packet from the
device or writing a packet to it must be atomic. Previously, only
reading device's vacancy (before writing on it) or occupancy (before
reading from it) was locked. Hence, effectively reading the packet or
writing the packet wasn't locked at all. However, reading a packet (and
writing one, to a lesser extent) requires to read 3 different registers
in a specific order, without missing one or else we should reset the
device.

This patch fixes the device's locking mechanism on the FIFO character
device. As the device was using copy_from_user() and copy_to_user(), we
need to replace spinlocks with mutexes.

The firmware now uses throughput enhancement code by default for SPI so
remove the previous implementation as its not used anymore. Removed the
use of 'has_thrpt_enh' element as its always true.

c5295d1a41 staging: wilc1000: move firmware API struct's to separate header file

9d442d2b9a staging: wilc1000: remove use of infinite loop conditions
Avoid the use of 'while (1)' infinite loop conditions. It's not
recommended to have infinite loop in kernel code because a small bug can
cause never ending loops so use terminator condition as suggested in
full driver review [1].

At present the driver does a number of checks for RX_FLAG_DECRYPTED.

Remove all these and just pass check NEWRSR_DECRYPTOK mac80211
will handle the processing of the sk_buff and dispose of it.

This means that mac80211 can do unsupported encryption modes
