[media] s5p-fimc: Correct memory allocation for VIDIOC_CREATE_BUFS
The commit 3b4c34aac7abea4754059084d0eef667a1993ac8
"s5p-fimc: Add support for VIDIOC_PREPARE_BUF/CREATE_BUFS ioctls"
added a handler for VIDIOC_CREATE_BUFS ioctl, but the queue_setup
callback wasn't updated to properly interpret the pixel format.
In this situation memory corruption may happen with VIDIOC_CREATE_BUFS
ioctl. Update the queue_setup op to fix this.

[media] s5p-fimc: Add support for alpha component configuration
On Exynos SoCs the FIMC IP allows to configure globally the alpha
component of all pixels for V4L2_PIX_FMT_RGB32, V4L2_PIX_FMT_RGB555
and V4L2_PIX_FMT_RGB444 image formats. This patch adds a v4l2 control
in order to let the applications control the alpha component value.
The alpha value range depends on the pixel format, for RGB32 it's
0..255 (8-bits), for RGB555 - 0..1 (1-bit) and for RGB444 - 0..15
(4-bits). The v4l2 control range is always 0..255 and the alpha
component data width is determined by currently set format on the
V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE buffer queue. The applications
need to match the alpha channel value range and the pixel format
since the driver will clamp the alpha component. Depending on
fourcc the valid alpha bits are:
- V4L2_PIX_FMT_RGB555 [0]
- V4L2_PIX_FMT_RGB444 [3:0]
- V4L2_PIX_FMT_RGB32 [7:0]
When switching to a pixel format with smaller alpha component width
the currently set alpha value will be clamped to maximum value valid
for current format. When switching to a format with wider alpha the
alpha value remains unchanged.
The variant description data structure is extended with a new entry
so an additional control is created only where really supported by
the hardware.
V4L2_PIX_FMT_RGB555 and V4L2_PIX_FMT_RGB444 formats are only valid
for V4L2_BUF_TYPE_VIDEO_CAPTURE buffer queue.

When requested more than 2 buffers the buffer dequeue order was wrong
due to erroneous updating FIMC registers in every interrupt handler
call. This also fixes regression of resetting the output DMA buffer
pointer at wrong time, when some buffers are already queued in hardware.
The hardware is reset in the start_streaming callback in order to align
the H/W state with the software output buffer pointer (buf_index).
Additionally a simple write to S5P_CISCCTRL register is replaced with
a read/modification/write to make sure the scaler is not being disabled

[media] s5p-fimc: Limit number of available inputs to one
The current driver allowed camera sensors to be used only with single
FIMC H/W instance, FIMC0..FIMC2/3, designated at compile time. Remaining FIMC
entities could be used for video processing only, as mem-to-mem devices.
Required camera could be selected with S_INPUT ioctl at one devnode only.
However in that case it was not possible to use both cameras independently
at the same time, as all sensors were registered to single FIMC capture
driver. In most recent S5P SoC version there is enough FIMC H/W instances
to cover all physical camera interfaces.
Each FIMC instance exports its own video devnode. Thus we distribute
the camera sensors one per each /dev/video? by default. It will allow to
use both camera simultaneously by opening different video node.
The camera sensors at FIMC are now not selected with S_INPUT ioctl, there
is one input only available per /dev/video?.
By default a single sensor is connected at FIMC input as specified by the
media device platform data subdev description table. This assignment
can be changed at runtime through the pipeline reconfiguration at the media
device level.

[media] media: vb2: change queue initialization order
This patch changes the order of operations during stream on call. Now the
buffers are first queued to the driver and then the start_streaming method
is called.
This resolves the most common case when the driver needs to know buffer
addresses to enable dma engine and start streaming. Additional parameter
to start_streaming method have been added to simplify drivers code. The
driver are now obliged to check if the number of queued buffers is high
enough to enable hardware streaming. If not - it can return an error. In
such case all the buffers that have been pre-queued are invalidated.
This patch also updates all videobuf2 clients to work properly with the
changed order of operations.

[media] Stop using linux/version.h on the remaining video drivers
Standardize the remaining video drivers to return the API version
for the VIDIOC_QUERYCAP version, instead of a per-driver version.
Those drivers had the version updated more recently or are SoC
drivers. Even so, it doesn't sound a good idea to keep a per-driver
version control, so, let's use the per-subsystem version control
instead.

When job_abort or stop_streaming was called to immediately shutdown
a memory-to-memory transaction video buffers scheduled for processing
were never returned to vb2 and v4l2_m2m_job_finish was not called
which led to hanging.
Correct this and also return the unprocessed buffers to vb2 marking

[media] s5p-fimc: fix ISR and buffer handling for fimc-capture
In some cases fimc H/W did not stop although there were no output
buffers available. So the capture deactivation interrupt routine
is modified and the state of ST_CAPT_RUN is cleared only
in the LAST-IRQ call.
After LAST-IRQ is generated, H/W pointer will be skipped by 1 frame.
(reference by user manual) So, S/W pointer should be increased too.

[media] s5p-fimc: update checking scaling ratio range
Horizontal and vertical scaling range are according to the following equations.
If (SRC_Width >= 64 x DST_Width) { Exit(-1); /* Out of Horizontal scale range}
If (SRC_Height >= 64 x DST_Height) { Exit(-1); /* Out of Vertical scale range}
fimc_check_scaler_ratio() is used to check if horizontal and vertical
scale range are valid or not. To use fimc_check_scaler_ratio,
source and destination format should be set by VIDIOC_S_FMT.
And in case of scaling up, it doesn't have to check the scale range.

FIMC 4.x has only two SFRs and FIMC 5.x has four SFRs for main scaler.
Those are MainHorRatio, MainHorRatio_ext, MainVerRatio and MainverRatio_ext.
The FIMC 5.x has 15 bit resolution for scaling ratio as below.
{MainHorRatio,MainHorRatio_ext} = {[14:6],[5:0]}.
{MainVerRatio,MainVerRatio_ext} = {[14:6],[5:0]}.
MainHorRatio = CISCCTRL[24:16], MainHorRatio_ext = CIEXTEN[15:10]
MainVerRatio = CISCCTRL[8:0], MainVerRatio_ext = CIEXTEN[5:0]
This patch supports FIMC 4.x and FIMC 5.x using platform_device_id::driver_data.
