[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.

[media] s5p-fimc: Fix buffer dequeue order issue
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
in fimc_hw_set_scaler().

[media] s5p-fimc: Convert to the new control framework
Convert the v4l controls code to use the new control framework.
fimc_ctrls_activate/deactivate functions are introduced for the
transparent DMA transfer mode (JPEG), where the rotation and flipping
controls are not supported.
The capture video node does not inherit sensors' controls when the
subdevs are configured by the user space (user_subdev_api == true).
However by default after the driver's initialization
the 'user-subdev_api' flag is false and any sensor controls will
also be available at the video node.
When the pipeline links are disconnected through the media device
the FIMC and any sensor inherited controls are destroyed and then
again created when the pipeline connection completes.

[media] s5p-fimc: Remove v4l2_device from video capture and m2m driver
Currently there is a v4l2_device instance being registered per each
(capture and memory-to-memory) video node created per FIMC H/W instance.
This patch is a prerequisite for using the top level v4l2_device
instantiated by the media device driver.
To retain current debug trace semantic (so it's possible to distinguish
between the capture and m2m FIMC) the video_device is used in place
of v4l2_device where appropriate.

[media] s5p-fimc: Add runtime PM support in the mem-to-mem driver
Add runtime PM and system sleep support in the memory-to-memory
driver. It's required to enable the FIMC operation on Exynos4
SoCs. This patch prevents system boot failure when the driver
is compiled in, as it now tries to access its I/O memory without
first enabling the corresponding power domain.
The camera capture device suspend/resume is not fully covered,
the capture device is just powered on/off during the video
node open/close. However this enables it's normal operation
on Exynos4 SoCs.

The description of FIFO_CTRL has been changed as below.
0 = FIFO Empty (Next burst transaction is possible when FIFO is empty)
1 = FIFO Full (Next burst transaction is possible except Full FIFO)
Value '1' is recommended to enhance the FIMC operation performance.

The main scaler has four SFRs for main scaler ratio depending on FIMC version.
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.
