Inside function mt9m114_detect(), variable "retvalue" could
be uninitialized if mt9m114_read_reg() returns error, however, it
is used in the later if statement, which is potentially unsafe.
The local variable "retvalue" is renamed to "model" to avoid
confusion.

RK3066's VPU IP block is the predecessor from what RK3288 has.
The hardware differences are:
- supports decoding frame sizes up to 1920x1088 only
- doesn't have the 'G1_REG_SOFT_RESET' register
(requires another .reset callback for hantro_codec_ops,
since writing this register will result in non-working
IP block)
- has one ACLK/HCLK per vdpu/vepu
- ACLKs can be clocked up to 300 MHz only
- no MMU
(no changes required: CMA will be transparently used)
Add a new RK3066 variant which reflect this differences. This variant
can be used for RK3188 as well.

Merge the two Rockchip platform drivers into one as it was suggested at
[1] and [2].
This will hopefully make it easier to add new variants (which are surely
to come for Rockchip).
Also rename from "rk3288" to "v(d/e)pu1" and "rk3399" to "v(d/e)pu2"
where applicable, as this is the dicition the vendor uses and will
also refelect the variants that get added later in this series. Rename
from "rk3288" to "rockchip" if applicable to both hardware versions.

We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

It doesn't support yet 10 bits formats or the scaling feature.
Add HANTRO HEVC dedicated control to skip some bits at the beginning
of the slice header. That is very specific to this hardware so can't
go into uapi structures. Computing the needed value is complex and requires
information from the stream that only the userland knows so let it

The variable reg_cur is being initialized with a value that is never
read, it is being updated later on. The assignment is redundant and
can be removed.

The driver should only set the payload on .buf_prepare if the
buffer is CAPTURE type. If an OUTPUT buffer has a zero bytesused
set by userspace then v4l2-core will set it to buffer length.
If we overwrite bytesused for OUTPUT buffers, too, then
vb2_get_plane_payload() will return incorrect value which might be then
written to hw registers by the driver in cedrus_h264.c or cedrus_vp8.c.
