Call buffer requirements before setting the min buffer size to
FW. Otherwise, in the case of event Sufficient, FW will
use outdated buffer size and error out. While at it, additional
buffer requirement call is added to get Output2 buffer requirement

Video driver will map the buffer twice in ETB/FTB. First map will
call iommu_map and following maps will just increment the refcount.
First unmap will happen in EBD/FBD and second unmap will happen if
READONLY flag is not present in EBD/FBD. If READONLY flag is not
present in EBD/FBD then video hardware will send RBR event
(Release Buffer Reference) to driver where second unmap will happen.
Though video driver calls iommu_unmap for second unmap the buffer
is not actually unmapped in iommu driver as video buffers are mapped
using late unmap feature. The buffer will get unmapped in iommu driver
when it is freed.

For usecases like High Speed Recording(HSR), High Frame
Recording(HFR), Video and Camera sub-systems need to exchange
more than 32 buffers. This is needed meet strict timing
requirements and to make sure that no sub-system is starving
for buffers due to latencies in both the SW stacks.
Currently, V4L2 framework supports buffer exchange for only 32
buffers. Hence increase the Max supported buffer counts from 32
to 64.

Currently we do not know what variant (bit length) of the nec protocol
is used, other than from guessing from the length of the scancode. Now
nec will be handled the same way as the sony protocol or the rc6 protocol;
one variant per bit length.
In the future we might want to expose the rc protocol type to userspace
and we don't want to be introducing this world of pain into userspace
too.

The rcar_fcp_enable() function immediately returns successfully when the
FCP device pointer is NULL to avoid forcing the users to check the FCP
device manually before every call. However, the stub version of the
function used when the FCP driver is disabled returns -ENOSYS
unconditionally, resulting in a different API contract for the two
versions of the function.
As a user that requires FCP support will fail at probe time when calling
rcar_fcp_get() if the FCP driver is disabled, the stub version of the
rcar_fcp_enable() function will only be called with a NULL FCP device.
We can thus return 0 unconditionally to align the behaviour with the
normal version of the function.
