This patch can make MIPI DSI panel probe successfully at the first
time, rather than depends on the PROBE_DEFER.
Besides, for the MIPI DSI panel used on imx8mm/imx8mq, the panel and
touch share one RST pin, touch need the panel do the RST first to wake

there are "subtle" differences.

Introduce new compatible string for QM to help us correctly
configure the DSP depending on the board they run.

We must find a way to no longer touch resources after they are

Now, after a stress test we get the following crash:

[ 2156.863772] fsl-dsp 596e8000.dsp: xf_pool_alloc failed

[ 2157.182754] [<ffff000008b11b24>] snd_compr_free+0x64/0x98

This happens because:

1) dsp_platform_process work handler waits in a loop for
   messages to arrive.
2) when cplay process finishes it cleans up most of the
   resources.
3) when another cplay process starts it reinitializes the
  resources including queues for example.
4) a message will be generated and kernel will crash because
   dsp_platform_process uses the older queues.

A solution for this is to make sure dsp_platform_process work loop
is stopped at cleanup time.

We use is_active state and signal dsp_platform_process handler to
finish because we are on the cleanup path.

While at it replace cancel_work with cancel_work sync to be sure
that work handler ends before going on with the rest of the cleanup.

MLK-19449: crypto: caam - Add Power Management

Add support for suspend and resume operation for PM in CAAM driver.

When the CAAM goes in suspend, the hardware is considered to do nothing.

On some platforms, the power of the CAAM is not turned off so it keeps
its configuration.

On other platforms, it doesn't so it is necessary to save the state of
the CAAM:
 - JRs MID
 - Address of input and output rings

Limitation:
When the CAAM is powered OFF, it is resetted so the JDKEK and TDKEK
changes. This impacts crypto transforms using MDHA split-keys
which are kept over suspend as they are encrypted with the JDKEK:
 - hmac(*) from caamhash.c
 - authenc(hmac(*),*) from caamalg.c
 - echainiv(authenc(hmac(*),*)) from caamalg.c
The issue was already present in current code so this patch does not
add a regression in this regard.

addresses and the notion of first_jr_index.

Instead the first JR available is set to index 0 of the table and so on.

Legacy code was retrieving the index of the first jr to access registers.
With this new way, we simply always access the first jr.

This is working because after the configuration of the JR in ctl
(enable_jobrings), the driver checks that there is at least 1 JR.
Without this, we could create segfaults.

The 'reset' pin used by this panel driver is shared with the touchscreen
driver, which is causing issues during suspend/resume process. In order
to better handle this gpio pin, release its resource during suspend and
acquire it again in resume.

Apparently, the pm_runtime_enable call is made too early, causing the PM
API printing this warning: 'Unbalanced pm_runtime_enable!'.
So move the call to pm_runtime_enable into the bind stage, which is more
appropriate than probe, since the disable is also made in unbind.

M4 complain that there are two much period done message sent to m4, that
M4 don't have enough time to handle these messages.

The solution for this issue is to reduce the number of period done message.
We allocate a specific memory for period done message, every time there is
period done coming, it will be writed to this memory, not write it directly
to the work queue, that queue will not be overflow, and the old period done
message will be overwrited.

In the rpmsg_i2s_work, we first check if there is period done message, then
send it first, after that, send the command in queue.
