6a26f141bf media: i2c: mt9t112: Remove soc_camera dependencies
Remove soc_camera framework dependencies from mt9t112 sensor driver.
- Handle clk, gpios and power routines
- Register async subdev
- Remove deprecated g/s_mbus_config operations
- Remove driver flags
- Change driver interface and add kernel doc
- Adjust build system
- Fix code style issues reported by checkpatch in strict mode

This commit does not remove the original soc_camera based driver as long
as other platforms depends on soc_camera framework.

As I don't have access to a working camera module, this change has only
been compile tested.

be2068bf64 media: adv7604: Add support for i2c_new_secondary_device
The ADV7604 has thirteen 256-byte maps that can be accessed via the main
I2C ports. Each map has it own I2C address and acts as a standard slave
device on the I2C bus.

Allow a device tree node to override the default addresses so that
address conflicts with other devices on the same bus may be resolved at
the board description level.

71569850e3 media: i2c: adv748x: Add missing CBUS page
The ADV748x has 12 pages mapped onto I2C addresses.

In the existing implementation only 11 are mapped correctly in the page
enumerations, which causes an off-by-one fault on pages above the
infoframe definition due to a missing 'CBUS' page.

This causes the address for the CEC, SDP, TXA, and TXB to be incorrectly
programmed during the iterations in adv748x_initialise_clients().

Until now this has gone un-noticed due to the fact that following the
creation of the clients - the device is reset and the addresses are
reprogrammed in manually by the call to "adv748x_write_regs(state,
adv748x_set_slave_address);"

As part of moving to dynamic i2c address allocations repair this by
providing the missing CBUS page definition.

As warned by smatch:
	drivers/media/i2c/s5c73m3/s5c73m3-core.c:268 s5c73m3_check_status() error: uninitialized symbol 'status'.

if s5c73m3_check_status() is called too late, time_is_after_jiffies(end)
will return 0, causing the while to abort before reading status.

The current code will do the wrong thing here, as it will still
check if status != value. The right fix here is to change
the logic to ensure that it will always read the status.

3ee9bc1234 media: cx25840: Use subdev host data for PLL override
The cx25840 driver currently configures 885, 887, and 888 using
default divisors for each chip. This check to see if the cx23885
driver has passed the cx25840 a non-default clock rate for a
specific chip. If a cx23885 board has left clk_freq at 0, the
clock default values will be used to configure the PLLs.

This patch only has effect on 888 boards who set clk_freq to 25M.

a2603d1748 media: i2c: max2175: use 64-bit arithmetic instead of 32-bit
Add suffix LL to constant 2 in order to give the compiler complete
information about the proper arithmetic to use. Notice that this
constant is used in a context that expects an expression of type
s64 (64 bits, signed).

The expression 2 * (clock_rate - abs_nco_freq) is currently being
evaluated using 32-bit arithmetic.

3dd6b560dc media: Don't let tvp5150_get_vbi() go out of vbi_ram_default array
As pointed by Dan, possible values for bits[3:0] of te Line Mode Registers
can range from 0x0 to 0xf, but the check logic allow values ranging
from 0x0 to 0xe.

As static arrays are initialized with zero, using a value without
an explicit initializer at the array won't cause any harm.

3b49842400 media: ov5640: fix framerate update
After a framerate update through s_frame_interval(), the new
framerate was not taken into account when streaming,
but was taken into account on next session.
This was due to sensor->current_mode not updated accordingly to new
framerate setting in ov5640_s_frame_interval().

01b8444828 media: v4l2: i2c: ov7670: Implement OF mbus configuration
ov7670 driver supports two optional properties supplied through platform
data, but currently does not support any standard video interface
property.

Add support through OF parsing for 2 generic properties (vsync and hsync
polarities) and for one custom property already supported through
platform data to suppress pixel clock output during horizontal
blanking.

While at there, check return value of register writes in set_fmt
function and rationalize spacings.

Signal polarities and pixel clock blanking verified through scope and
image capture.
