Initialize the context on open() with valid capture and output
formats. It is good practice to always have valid formats internally.
This solves one vb2 warning in the kernel log where the sizeimage
value of the output format was 0 when requesting buffers, which is
not allowed.
It also simplifies the g_fmt ioctl implementations since they no longer
have to check if a valid format was ever set.
cedrus_prepare_format() now also validates sizeimage for the output
formats, ensuring userspace can't set it to 0 since that would cause
the same vb2 warning.
Finally remove the sizeimage == 0 check in cedrus_try_fmt_vid_out()
since cedrus_prepare_format() will now adjust this value.

The try_fmt was not actually trying out the provided format
but merely returning the current format basically like get_fmt.
In addition set_fmt should first invoked try_fmt to validate the
given format before applying it to the hardware.
To fix all of these the whole get/try/set ioctl functions had to
be reworked.
When calculating the bytesperline/stride and sizeimage format
member we don't need to locally store the current value of
bytesperpixel as it can easily get derived dynamically.

We were originally attempting to stop all processing as soon
as possible, but the in-progress DMA operation cannot be canceled.
This led to the module being in a busy state and prevented proper
power management functionality.
The existing implementation would attempt to clean things up by waiting
up to 50ms. However when receiving video frame at 15fps or lower,
it meant an inter frame arrival rate of 66.6 ms or higher.
In such cases upon tear down the following message could be seen:
omap_hwmod: vpfe0: _wait_target_disable failed
This patch fixes this issue by adding a stopping state where
we would wait for the next Vsync before disabling the hardware.

vimc uses Component API to split the driver into functional components.
The real hardware resembles a monolith structure than component and
component structure added a level of complexity making it hard to
maintain without adding any real benefit.
The sensor is one vimc component that would makes sense to be a separate
module to closely align with the real hardware. It would be easier to
collapse vimc into single monolithic driver first and then split the
sensor off as a separate module.
Collapse it into a single monolithic driver removing the Component API.
This patch removes the component API and makes minimal changes to the
code base preserving the functional division of the code structure.
Preserving the functional structure allows us to split the sensor off
as a separate module in the future.
Major design elements in this change are:
- Use existing struct vimc_ent_config and struct vimc_pipeline_config
to drive the initialization of the functional components.
- Make vimc_device and vimc_ent_config global by moving them to
vimc-common.h
- Add two new hooks add and rm to initialize and register, unregister
and free subdevs.
- All component API is now gone and bind and unbind hooks are modified
to do "add" and "rm" with minimal changes to just add and rm subdevs.
- vimc-core's bind and unbind are now register and unregister.
- Add a new field to vimc_device structure for saving the pointers to
struct vimc_ent_device(s) subdevs create in their "add" hooks. These
get used to create links and removing the subdevs. vimc-core allocates
this array which sized to number of entries in the topology defined in
the vimc_pipeline_config structure.
- vimc-core invokes "add" hooks from its vimc_register_devices().
The "add" hooks remain the same and register subdevs. They don't
create platform devices of their own and use vimc's pdev.dev as
their reference device. Each "add" hook returns pointer to its struct
vimc_ent_device. This is saved in the vimc_device ent_devs array.
- vimc-core invokes "rm" hooks from its unregister to unregister subdevs
and cleanup.
- vimc-core invokes "add" and "rm" hooks with pointer to struct vimc_device
and the corresponding vimc_ent_device saved in the ent_devs.
The following configure and stream test works on all devices.
media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]'
media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]'

Move the static keyword to the front of declaration of
csky_pmu_of_device_ids, and resolve the following compiler
warning that can be seen when building with warnings
enabled (W=1):
arch/csky/kernel/perf_event.c:1340:1: warning:
‘static’ is not at beginning of declaration [-Wold-style-declaration]

Since the enabling and disabling of IRQs within preempt_schedule_irq()
is contained in a need_resched() loop, we don't need the outer arch
code loop.
