27ffaeb0ab [media] platform: Make use of media_bus_format enum
In order to have subsytem agnostic media bus format definitions we've
moved media bus definition to include/uapi/linux/media-bus-format.h and
prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.

Reference new definitions in all platform drivers.

8dece35daf [media] dm644x_ccdc: use unsigned long for fpc_table_addr
The fpc_table_addr is used as an unsigned integer that stores
an address. At the Kernel, the proper type for such integers
is unsigned long.

This generates lots of warnings when compiling on 64 bits.

314527acbb [media] v4l2: pass std by value to the write-only s_std ioctl
This ioctl is defined as IOW, so pass the argument by value instead of by
reference. I could have chosen to add const instead, but this is 1) easier
to handle in drivers and 2) consistent with the s_std subdev operation.

1de1951930 [media] davinci/dm644x_ccdc: fix compiler warning
drivers/media/platform/davinci/dm644x_ccdc.c: In function ‘validate_ccdc_param’:
drivers/media/platform/davinci/dm644x_ccdc.c:233:32: warning: comparison between ‘enum ccdc_gama_width’ and ‘enum ccdc_data_size’ [-Wenum-compare]
It took a bit of work, see this thread of an earlier attempt to fix this:
https://patchwork.kernel.org/patch/1923091/
I've chosen not to follow the suggestions in that thread since gamma_width is
really a different property from data_size. What you really want is to know if
gamma_width fits inside data_size and for that you need to translate each
enum into a maximum bit number so you can safely compare the two.
So I put in two static inline translation functions instead, keeping the rest
of the code the same (except for fixing the 'gama' typo).

caff80c35f [media] davinci: vpbe: pass different platform names to handle different ip's
The vpbe driver can handle different platforms DM644X, DM36X and
DM355. To differentiate between this platforms venc_type/vpbe_type
was passed as part of platform data which was incorrect. The correct
way to differentiate to handle this case is by passing different
platform names.
This patch creates platform_device_id[] array supporting different
platforms and assigns id_table to the platform driver, and finally
in the probe gets the actual device by using platform_get_device_id()
and gets the appropriate driver data for that platform.
Taking this approach will also make the DT transition easier.

2bd4e58c9d [media] media: davinci: vpif: display: separate out subdev from output
vpif_display relied on a 1-1 mapping of output and subdev. This is not
necessarily the case. Separate the two. So there is a list of subdevs
and a list of outputs. Each output refers to a subdev and has routing
information. An output does not have to have a subdev.
The initial output for each channel is set to the fist output.
Currently missing is support for associating multiple subdevs with
an output.
