04320b3ef9 media: allegro: fix potential null dereference on header
The pointer header is an alias to msg and msg is being null checked.
However, if msg is null then header is also null and this can lead to
a null pointer dereference on the assignment type = header->type. Fix
this just using header->type after the null check and removing the need
for type as it is only used once.

  The diffstat is a bit long, as this driver has several abstractions.
  The patches that solved the issues with W=1 had to get rid of some
  duplicated code (there used to have 2 versions of the same code, one
  for ISP2401 and another one for ISP2400).

  As this driver is not in 5.7, such changes won't cause regressions"

Currently the 'pads' and 'pad_cfg' arrays of the rkisp1_resizer
are of size 'RKISP1_ISP_PAD_MAX' which is 4. But the resizer
has only two pads. Change the size of the arrays to 2 by adding

the isp entity.

aa86e0bbf2 media: staging: rkisp1: cap: don't set next buffer from rkisp1_vb2_buf_queue
The function 'rkisp1_vb2_buf_queue' sets the next buffer directly
in case the capture is already streaming but no frame yet arrived
from the sensor. This is an optimization that tries to avoid
dropping a frame.
The call atomic_read(&cap->rkisp1->isp.frame_sequence) is used
to check if a frame arrived. Reading the 'frame_sequence' should
be avoided outside irq handlers to avoid race conditions.

This patch removes this optimization. Dropping of the first
frames can be avoided if userspace queues the buffers before
start streaming. If userspace starts queueing buffers
only after calling 'streamon' he risks frame drops anyway.

won't be the actual length of the message that is send to the firmware.
Therefore, drop the length field from the message.

decode it once before dispatching to the respective functions.

c4756d8774 media: allegro: add config blob for channel
Firmware versions >= 2019.2 do not configure the channel via the mailbox
interface anymore, but use a separate chunk of memory that is only
referenced by the message. As the configuration must be in a format that
is understood by the firmware and this format can change between
firmware versions, handle it similar to the message and treat is as a
blob.

In order to support both methods in the driver, always use a separate
blob for the channel configuration and copy that blob into the mailbox
if the firmware requires it and otherwise reference it.

d30e841216 media: allegro: encode bit fields separately
Even bits in bitfields do not keep their position, but move around or
move to other bitfields. Therefore, the driver has to handle bitfields
differently depending on the firmware version.

Create separate fields for the options that have been in bitfields and
handle the bitfields when encoding the message.

As a side effect, this makes the messages a bit more readable.

3de1683966 media: allegro: add explicit mail encoding and decoding
The message format in the mailboxes differ between firmware versions.
Therefore, it is necessary to decouple the mailbox format of the driver
from the message format of the firmware. This allows to keep a
consistent message format in the driver while still supporting various
firmware versions.

Add an intermediate step to encode and decode message before writing the
mails to the mailboxes.

On the other hand, this allows to handle optional fields in the
messages, which is required for advanced features of the encoder and was
not possible until now.

e561f8e24c media: allegro: rework read/write to mailbox
Rework the functions that read and write the SRAM that is used to
communicate with the MCU.

As the functions will not operate on structs but on prepared binary
buffers, make the buffer stride more explicit. Also, avoid any uses of
struct mcu_msg_header to analyze messages in memory, because the header
will be made independent of the binary representation in the mailbox.
Instead explicitly access the mail size field in the mailbox.

As at it, further reduce the dependency between the mailboxes and struct
allegro_dev.

94dc765602 media: allegro: rework mbox handling
Add a send/notify abstraction for the mailbox and separate the message
handling in the driver from the code to read and write message to the
mailbox.

This untangles how mails are written into the MCU's SRAM and signaled to
the MCU from the protocol between the driver and the firmware.

Currently the check on bits 25:24 on ISPSSPM0 is always 0 because
the mask and shift operations are incorrect. Fix this by shifting
by MRFLD_ISPSSPM0_ISPSSS_OFFSET (24 bits right) and then masking
with RFLD_ISPSSPM0_ISPSSC_MASK (0x03) to get the appropriate 2 bits
to check.

e765dba11e hantro: Move hantro_enc_buf_finish to JPEG codec_ops.done
hantro_enc_buf_finish is used only for JPEG, and so should
be moved to JPEG codec_ops.done.

This cleanup is also taking care of addressing
a subtle issue: checking the non-NULL bounce buffer
using ctx->jpeg_enc, which is a member of a union is
confusing and error-prone.

Note that the issue is currently innocuous because an
encoder context only supports JPEG.

The codec_ops.done has an argument that codec-specific code
shouldn't need, so drop that as well.

It replaces them with one spin_lock 'lock' that protects
both the buffers list and the 'is_streaming' variable.
In later patch the reading of the statistics will move to
the isr so there will be no need for the mutex 'wq_lock'

08b2bcc665 media: atomisp: get rid of version-specific system_local.h
After removing the unused 32-bits data, the isp2401_system_local.h
now contains everything that it is needed, either by isp2401 or
by isp2400.

So, remove code duplication.

4b28ded763 media: atomisp: move global stuff into a common header
Right now, there are two versions of system_global.h headers.

Both share a lot of common code. There are some ISP2401 specific
types on one of the headers, but it doesn't conflict with the
ISP2400 ones.

Also, the common code is identical.

So, remove code duplication by moving such code into a
common header.

a6154805d0 media: atomisp: remove non-used 32-bits consts at system_local
There is an abstraction at the code in order to support
32 or 64 bits address/data length. However, for all
Atom chipsets supported by this version, the size is fixed.

So, cleanup the mess, removing the uused code and placing
the data sizes on a single place.

The end goal is to completely remove those local/global
headers, replacing them by some ISP-version dependent struct,
in order for the driver to decide what version it would need
in runtime.

ecf1b4ca97 media: atomisp: get rid of some unused static vars
There are several static vars declared inside the
system local headers. This causes lots of warnings when W=1.

Remove the unused ones.

If gmin_camera_platform_data() returns NULL then we should return a
