Mailbox driver needs to wait and read all the words in response to a
SCFW API call, else the protocol gets messed up and results in kernel hang.
When the responses are longer than 3 words its possible that SCFW will
take some time to fill up the rest of the words in the MU, a timeout of
100us is arbritrary and too short. While waiting for Linux to consume the
first 3 words of the response SCFW can be busy doing other stuff and hence
Linux needs to wait for the rest of the words.
Similar restriction applies when writing messages that are longer than
3 words.
This patch increases the timeout to 5secs while waiting for response
or writing long messages to SCFW.Signed-off-by: Ranjani Vaidyanathan

Add a new member jpeg_parse_error in mxc_jpeg_src_buf, to indicate
an error while parsing the input jpeg stream.
Do not run the decoder when the source buffer is marked with
jpeg_parse_error, instead mark both the source and destination
buffer with VB2_BUF_STATE_ERROR. This will prevent an application
getting stuck waiting to dequeue the destination buffer.Signed-off-by: Mirela Rabulea

End of buffer was not properly detected in case of an invalid
buffer stream, such as a stream of null bytes, for example.
This was leading to a kernel oups.
Let get_byte return type be int, so it can return an error for
reaching end of stream.While at it, replace 0 with NULL, for null pointer initialization.

Clocks are always on when DSP PD is on. Use dummy clocks
for minimal code impact for now.This is similar with the approach on i.MX8QM.
Signed-off-by: Daniel Baluta

This is similar with the refactor for i.MX8MP added in commit
ba2d283f5d9 ("LF-3026-2 ASoC: SOF: imx8m: Remove internal
priv->suspended variable").Because SOF state machine assumes that even if the DSP wasn't previously
active at a System resume, will re-load the firmware we need to make sure
that all needed resources are active.Kernel core will take care of enabling the PD, we need to make sure that
we request the MU channels.Signed-off-by: Daniel Baluta

For some tough multi channels test, the default priority of channel0 may
not be scheduled in 500us so that channel context can't be loaded as the
below warning, hence sdma channel transfer will be failed. So raise up
channel0 to the highest one since context load is important to all
channels. Besides, enlarge 500us to 5ms for safe since many highest channel
also may run at the same time like asrc/easrc tough test(8 channel run)."imx-sdma 30e10000.dma-controller: Timeout waiting for CH0 ready"

The latest batch of RM67191 panels have an issue that the panel display
will get blurred and have no response to later display actions when read
data from panel through DSI interface.And decrease the pixel clock rate to 121MHz which means decrease the
panel's frame rate from 60.02Hz to 55.02Hz can solve this issue, so
do this change to make RM67191 display more stable.Signed-off-by: Fancy Fang

This reverts commit cd74693870fb748d812867ba49af733d689a3604.
This is a workaround for allowing dm-crypt crypto operations to be
offloaded to caam crypto accelerator.
It's needed because crypto algorithms registered by caam are marked with
CRYPTO_ALG_ALLOCATES_MEMORY flag.Background:
Red Hat reported possible allocation issues in dm-crypt, dm-integrity:
Link: https://lore.kernel.org/linux-crypto/alpine.LRH.2.02.2006091259250.30590@file01.intranet.prod.int.rdu2.redhat.com
The solution found was a mechanism to let dm-crypt, dm-integrity avoid
using crypto algorithms that allocate memory "at runtime" - by specifying
the CRYPTO_ALG_ALLOCATES_MEMORY flag introduced in

After rotations were introduced for Vivante tiled/super-tiled formats and these
formats were also allowed for video channels, the tile type was adjusted only
if the framebuffer modifier was linear or belonged to Vivante tiled types. For
tiled video formats, the modifier is none of those and the tiled type remained
unchanged from the previous run.Tiled video formats are handled by DTRC and DPR always fetches the linear buffers
directly from DTRC.This patch fixes the regression. Also, add a meaningful error message if a wrong
modifier is passed to DPR for the graphics/video path.Fixes: 69c833ef382c ("LF-2580: drm/imx/dcss: add 90/270 rotations for Vivante tiled formats.")

Some HDR10 pipe configurations are not supported by DCSS.
The general idea is to use atomic check to reject the unsupported cases
by searching the array dcss_cfg_table[] to see if a valid entry can be found
or not. To do the atomic check correctly, we should track the output pipe
configurations, which is done by the newly introduced struct dcss_crtc_state.
The plane->atomic_check() function would finally check the input and output
pipe configurations by calling the helper function
dcss_plane_hdr10_pipe_cfg_is_supported().Tested-by: Laurentiu Palcu
