Use IMX283_STANDBY (bit 0) instead of IMX283_STBLOGIC (bit 1) when
stopping streaming. STBLOGIC only puts the sensor logic into standby but
leaves the MIPI interface (along with other components) in an
indeterminate state.
This (presumably) causes the CSI receiver (e.g. Raspberry Pi's CFE) to
miss the LP-11 to HS transition when streaming restarts, resulting in a
hang of 10+ seconds. The issue is most visible when immediately
restarting a full-resolution stream after stopping a 3x3 binned one, so
that runtime suspend hasn't yet been triggered.
Writing IMX283_STANDBY puts the entire sensor into standby. The
imx283_standby_cancel() sequence already handles the full wakeup from
this suspended state.

When the CCS_PLL_FLAG_EXT_IP_PLL_DIVIDER flag is set, odd pre-PLL divider
values are allowed. However, in the operational timing branch the
calculation of the minimum pre-PLL divider incorrectly uses clk_div_even_up,
forcing the minimum value to be even, even if the flag is set. This prevents
selecting a valid odd divider like 3, which may be required for certain
sensor configurations.
Fix this by removing the forced even rounding from the minimum pre-PLL
divider calculation. The loop later uses the flag to determine the step,
so odd values will be considered when the flag is set.

indicating that a sleepable GPIO was called via the non-sleeping APIs on

Currently the active use of the GPIO is all done from process context so
can be simply converted to use gpiod_get_value_cansleep(). There is one use
of the GPIO from hard interrupt context but this is only done so the status
can be displayed in a debug print so can simply be deleted without any
functional effect.

Add possibility to rely on an additional MDMA channel and chain
the DMA and MDMA channels allowing to achieve faster capture.
Indeed, on the MP15 platform, the MDMA engine has an higher
bandwidth to the DDR than the DMA engine. Relying on that
it is possible to capture frames from the DCMI IP into the DDR
by using two channels as follow:
DCMI -> (DMA) -> SRAM -> (MDMA) -> DDR
The DMA is able by himself to trigger a MDMA request hence, once
properly configured, the DCMI IP can simply trigger the DMA in order
to have the data pushed up to the DDR (via the SRAM and a MDMA
channel).
This behavior is detailed in the document

Whenever receiving an OVERRUN event or an end of frame, the driver stops
currently ongoing DMA transfer since the DCMI stops sending data to dma.
Not doing this would lead to having DMA & DCMI no more synchronized in term
of expected data to be copied.
Since this is done in irq handler context, it is not possible to make any
call that would lead to scheduling hence dmaengine_terminate_sync are not
possible.
Since the dcmi driver is NOT using dma callbacks, it is possible thus to
call instead dmaengine_terminate_async (aka without synchronize) and call
again right after a new dmaengine_submit to setup again a new transfer.
And since this is now a dmaengine_submit_async, there is no need to release
the spinlock around calls to the dmaengine_submit_async.

Move all the type of frame handling within the dcmi_irq_thread
handler and do not rely on dma_callback as previously.
This simplifies the code by having only a single path for both
compressed and uncompressed data while also making the system
more reactive since irq_handler have more chances to be called
faster than the dma completion callback. Indeed, in case of the
dma completion callback, this run as a tasklet created by the
dma framework upon getting an interrupt from the dma and run
at a lower priority level than other irq handlers.

The deferred page initialization prevents debug objects from allocating
slab pages until the initialization is complete. That causes depletion of
the pool and disabling of debugobjects.
The reason is that debugobjects uses __GFP_HIGH for allocations as it might
be invoked from arbitrary contexts. When PREEMPT_COUNT is disabled there is
no way to know whether the context is safe to set __GFP_KSWAPD_RECLAIM.
This worked until v6.18. Since then allocations w/o a reclaim flag cause
new_slab() to end up in alloc_frozen_pages_nolock_noprof(), which returns
early when deferred page initialization has not yet completed.
Work around that when PREEMPT_COUNT is enabled as the preempt counter
allows debugobjects to add __GFP_KSWAPD_RECLAIM to the GFP flags when the
context is preemtible. When PREEMPT_COUNT is disabled the context is
unknown and the reclaim bit can't be set because the caller might hold
locks which might deadlock in the allocator.
That makes debugobjects depend on PREEMPT_COUNT || !DEFERRED_STRUCT_PAGE_INIT,
which limits the coverage slightly, but keeps it functional for most cases.
