8f9061fa77 media: sunxi-cir: Factor out hardware initialization
In preparation for adding suspend/resume hooks, factor out the hardware
initialization from the driver probe/remove functions.

The timeout programmed during init is taken from the `struct rc_dev` so
it is maintained across an exit/init cycle.

This resolves some trivial issues with the probe function: throwing away
the error from clk_prepare_enable and using the wrong type for the
temporary register value.

It also fixes the order of the remove function to unregister the RC
device before turning off the hardware. This prevents userspace from
triggering register writes (via LIRC_SET_REC_TIMEOUT) while the hardware
is disabled.

d1036eb43f media: sunxi-cir: Remove unnecessary spinlock
Only one register, SUNXI_IR_CIR_REG, is accessed from outside the
interrupt handler, and that register is not accessed from inside it.

803abec64e media: ipu3-cio2: Add cio2-bridge to ipu3-cio2 driver
Currently on platforms designed for Windows, connections between CIO2 and
sensors are not properly defined in DSDT. This patch extends the ipu3-cio2
driver to compensate by building software_node connections, parsing the
connection properties from the sensor's SSDB buffer.

ae56e038f7 media: ccs: Make (non-)use of uninitialised variables more robust
GCC with W=2 level of kernel compiler warnings warns about the use of
uninitialised variables in a few locations. While these uninitialised
variables were not used in reality, this still produced compiler warnings.

Address this by assigning the variables to NULL and checking for NULL in
places it is not expected, returning -EIO in that case. This provides
at least some sanity checking at runtime as the compiler appears unable to
do that at compile time.

c8e8dabcd1 media: venus: vdec: Handle DRC after drain
If the DRC is near the end of the stream the client
may send a V4L2_DEC_CMD_STOP before the DRC occurs.
V4L2_DEC_CMD_STOP puts the driver into the
VENUS_DEC_STATE_DRAIN state.  DRC must be aware so
that after the DRC event the state can be restored
correctly.

d5ee32d7e5 media: venus: preserve DRC state across seeks
DRC events can happen virtually at anytime, including when we are
starting a seek. Should this happen, we must make sure to return to the
DRC state, otherwise the firmware will expect buffers of the new
resolution whereas userspace will still work with the old one.

Returning to the DRC state upon resume for seeking makes sure that the
client will get the DRC event and will reallocate the buffers to fit the
firmware's expectations.

21560ddf78 media: venus: helpers: Lock outside of buffer queue helper
After adding more logic in vdec buf_queue vb2 op it is not
practical to have two lock/unlock for one decoder buf_queue.
So move the instance lock in encoder and decoder vb2 buf_queue
operations.

a4ca67af8b media: venus: vdec: Make decoder return LAST flag for sufficient event
This makes the decoder to behaives equally for sufficient and
insufficient events. After this change the LAST buffer flag will be set
when the new resolution (in dynamic-resolution-change state) is smaller
then the old bitstream resolution.

acf8a57d8c media: venus: vdec: Fix non reliable setting of LAST flag
In real use of dynamic-resolution-change it is observed that the
LAST buffer flag (which marks the last decoded buffer with the
resolution before the resolution-change event) is not reliably set.

Fix this by set the LAST buffer flag on next queued capture buffer
after the resolution-change event.

cc82fd691a media: venus: use contig vb2 ops
This driver uses the SG vb2 ops, but effectively only ever accesses the
first entry of the SG table, indicating that it expects a flat layout.
Switch it to use the contiguous ops to make sure this expected invariant
is always enforced. Since the device is supposed to be behind an IOMMU
this should have little to none practical consequences beyond making the
driver not rely on a particular behavior of the SG implementation.
