reset_gpio needs to be an output and set to GPIOD_OUT_LOW, to ensure
lt6911uxe is in reset state during probe.
This issue was found on the onboard lt6911uxe, where the reset_pin was
not reset, causing the lt6911uxe to fail to probe.

Getting / Setting the frame interval using the V4L2 subdev pad ops
get_frame_interval/set_frame_interval causes a deadlock, as the
subdev state is locked in the [1] but also in the driver itself.
In [2] it's described that the caller is responsible to acquire and
release the lock in this case. Therefore, acquiring the lock in the
driver is wrong.
Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval()
and mt9m114_ifp_set_frame_interval().

The function mt9m114_configure writes the configuration registers of both,
the pixel array (pa) and the image flow processor (ifp).
This is undesirable if only the config of the pa should be changed without
affecting the ifp.
Factor out the function mt9m114_configure_pa() that just writes the
pa-configuration.

The MT9M114 sensor has an internal PLL that generates the required SYSCLK
from EXTCLK. It also has the option to bypass the PLL and use EXTCLK
directly as SYSCLK.
The current driver implementation uses a hardcoded PLL configuration that
requires a specific EXTCLK frequency. Depending on the available clocks,
it can be desirable to use a different PLL configuration or to bypass it.
The link-frequency of the output bus (Parallel or MIPI-CSI) is configured
in the device tree.
Check if EXTCLK can be used as SYSCLK to achieve this link-frequency. If
yes, bypass the PLL.
Otherwise, (as before) check if EXTCLK and the default PLL configuration
provide the required SYSCLK to achieve the link-frequency. If yes, use the
PLL. If no, throw an error.

The MT9M114 supports the different slew rates (0 to 7) on the output pads.
At the moment, this is hardcoded to 7 (the fastest rate).
The user might want to change this values due to EMC requirements.
Add the 'slew-rate' property to the MT9M114 DT-bindings for selecting
the desired slew rate.

Switch to u64 arithmetic and use DIV_ROUND_CLOSEST_ULL() to avoid
the overflow.
buffer[i] is unsigned int and is limited by the lirc core to
IR_MAX_DURATION, which is 500000.
idata->freq is u32, which has a max value of 0xFFFFFFFF.
In the case where buffer[i] is 500000, idata->freq overflows the u32
multiplication for any values >= 8590.
0xFFFFFFFF / 500000 ~= 8589
By casting buffer[i] to u64, idata->freq can be any u32 value without
overflowing the multiplication.
0xFFFFFFFFFFFFFFFF / 500000 ~= 36893488147419 (> 4294967295)
The result of the final operation will fit back into the unsigned int
limits without any issues.
500000 * 0xFFFFFFFF / 1000000 = 0x80000000 (< 0xFFFFFFFF)

On errors, the rkvdec chip self resets. This can clear the addresses
programmed in the iommu. This case is signaled by the
RKVDEC_SOFTRESET_RDY status bit.
Since the iommu framework does not have a restore functionality, and
as recommended by the iommu subsystem maintainers, this patch
restores the iommu programming by attaching and detaching an empty
domain, which will clear and restore the default domain.

word difference between them. The word is moved out of the format string
to a separate dev_err() argument to try and save memory through string
de-duplication. The total savings are however small, as the .data size
reduction is partly offset by a .text size increase, with a total saving
of 8 bytes in total on an ARM64 platforms. They also come at the cost of
making the error message difficult to grep, which outweights the gains.
Simplify the error messages to make them grep-able.

Add support for VSPX, a specialized version of the VSP2 that
transfers data to the ISP. The VSPX is composed of two RPF units
to read data from external memory and an IIF instance that performs
transfer towards the ISP.
The VSPX is supported through a newly introduced vsp1_vspx.c file that
exposes two interfaces: vsp1_vspx interface, declared in vsp1_vspx.h
for the vsp1 core to initialize and cleanup the VSPX, and a vsp1_isp
interface, declared in include/media/vsp1.h for the ISP driver to
control the VSPX operations.

To detect leaks of display lists, store in the display list manager the
number of allocated display lists when the manager is created and verify
that when the display manager is reset the same number of lists is
available in the free list.

In order to detect invalid usage pattern such as double list_put()
calls, add an 'allocated' flag to each display list. Set the flag
whenever a list is get() and clear it when the list is put(). Warn if a
list not marked as allocated is returned to the pool of available
display lists.
