The s5p-fimc directory now contains drivers for multiple IP blocks
found in multiple Samsung application processors. This includes FIMC
(CAMIF), MIPI CSIS and FIMC LITE. FIMC-IS (Imaging Subsystem) driver
is going to be put into same directory. Hence we rename it to
exynos4-is as s5p-fimc was only relevant for early version of this
driver, when it only supported FIMC IP block.
The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will
be included in drivers/media/platform/exynos4-is directory, with some
modules shared with exynos5 series, while the rest of exynos5 specific
modules will find their home in drivers/media/platform/exynos5-is.

Since the FIMC-IS firmware communicates with an image sensor directly
through the ISP I2C bus controllers the sub-devices power supplies
cannot be simply enabled from left to right or disabled from right
to left along the processing pipeline. Thus a subdev index to call
s_power() on is looked up from a table, rather than doing the op call
based on increasing/decreasing indexes.

In configurations where FIMC-LITE is used to capture image signal
from an external sensor only we need to ensure one of FIMC devices
is in active power state and the "fimc" gate clock is enabled.
Otherwise the CAMCLK clock output signal will be masked off
preventing an external sensor's operation.
This affect processing pipelines like:
- sensor -> FIMC-LITE -> memory
- sensor -> MIPI-CSIS -> FIMC-LITE -> memory

A second sink pad is added to each FIMC.N subdev that will be used
to link it to the FIMC-IS-ISP subdev. Only V4L2_MBUS_FMT_YUV10_1X30
format is supported at this pad (FIMC_SD_PAD_SINK_FIFO).
The routine checking for mismatch in the image formats at sides of
the links is updated to account for the fact FIMC.X subdevs now have
sink pads at the pad indexes 0, 1 and source pad at pad index 2.
If link to FIMC.X pad 1 is activated we switch FIMC input data bus
type to the ISP Writeback. Only a single active link to FIMC.X pad 0
or 1 will be allowed at any time.

The sensor (I2C and/or SPI client) devices are instantiated by their
corresponding control bus drivers. Since the I2C client's master clock
is often provided by a video bus receiver (host interface) or other
than I2C/SPI controller device, the drivers of those client devices
are not accessing hardware in their driver's probe() callback. Instead,
after enabling clock, the host driver calls back into a sub-device
when it wants to activate them. This pattern is used by some in-tree
drivers and this patch also uses it for DT case. This patch is intended
as a first step for adding device tree support to the S5P/Exynos SoC
camera drivers. The second one is adding support for asynchronous
sub-devices registration and clock control from sub-device driver
level. The bindings shall not change when asynchronous probing support
is added.

when irq is serviced, a NULL pointer dereference occurs.
Also, the isr routine must be registered only if no error occurs, otherwise
the isr triggers without the proper setup, and the kernel oops again.
To prevent this, the error condition is checked, and the streamon function
exits with error. Also the isr registration call is moved after the setup

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).
