c61e74e3a8 [media] media: mt9m111: move mt9m111 out of soc_camera
As the mt9m111 is now working as a standalone v4l2 subdevice sensor,
move it out of soc_camera directory and sever its dependency on
soc_camera.

5d7cc01b20 [media] media: mt9m111: make a standalone v4l2 subdevice
Remove the soc_camera adherence. Mostly the change removes the power
manipulation provided by soc_camera, and instead :
 - powers on the sensor when the s_power control is activated
 - powers on the sensor in initial probe
 - enables and disables the MCLK provided to it in power on/off

This patch also drops support for inverters on synchronisation and clock
lines. It is assumed, if any board ever needs such inverters, support
for them can be added in the future

5a08bc008d [media] tvp5150: use sd internal ops .registered instead .registered_async
The driver is using the struct v4l2_subdev_core_ops .registered_async
callback to register the connector entities and create the pad links
after the subdev entity has been registered with the media device.

But the .registered_async callback isn't needed since the v4l2 core
already calls the struct v4l2_subdev_internal_ops .registered callback
in v4l2_device_register_subdev(), after media_device_register_entity().

So, use the .registered() callback instead of the .registered_async()
that is going to be removed in a following patch since isn't needed.

pending when the driver is disconnected.

fd74246d2a [media] adv7604/adv7842: fix quantization range handling
Fix a number of bugs that appeared when support for mediabus formats was
added:

- Support for V4L2_DV_RGB_RANGE_FULL/LIMITED should only be enabled
  for HDMI RGB formats, not for YCbCr formats. Since, as the name
  says, this setting is for RGB only. So read the InfoFrame to check
  the format.

- the quantization range for the pixelport depends on whether the
  mediabus code is RGB or not: if it is RGB, then produce full range
  RGB values, otherwise produce limited range YCbCr values.

  This means that the op_656_range and alt_data_sat fields of the
  platform data are no longer used and these will be removed in a
  following patch.

- when setting up a new format the RGB quantization range settings
  were never updated. Do so, since this depends on the format.

- fix the log_status output which was confusing and incorrect.

0a25a01251 [media] adv7511: fix quantization range handling
Commit 1fb69bfd29 (adv7511: improve
colorspace handling) introduced a number of bugs, specifically with
regards to YCbCr output and quantization range handling:

- if the output is not RGB, then disable the full-to-limited range
  CSC matrix since that is meant for RGB formats. YCbCr formats are
  always limited range, so there is nothing to convert. (OK, full
  range YCbCr is possible, but we don't support that right now).

- the mediabus code that was passed to adv7511_set_fmt was always cleared
  by the memset in adv7511_fill_format. This made it effectively impossible
  to select YCbCr output.

- adv7511_set_fmt never updated the rgb quantization range.

78060d5195 [media] v4l: mt9v032: Do not unset master_mode
The power_on function of the driver resets the chip and sets the
CHIP_CONTROL register to 0. This switches the operating mode to slave.
The s_stream function sets the correct mode. But this caused problems on
a board where the camera chip is operated as master. The camera started
after a random amount of time streaming an image, I observed between 10
and 300 seconds.

The STRFM_OUT and STLN_OUT pins are not connected on this board which
may cause some issues in slave mode. I could not find any documentation
about this.

Keeping the chip in master mode after the reset helped to fix this
issue for me.

f823a3fd4b [media] v4l: mt9v032: Remove duplicate test for I2C_FUNC_SMBUS_WORD_DATA functionality
Since commit b42261078a ("regmap: i2c: fallback to SMBus if the adapter
does not support standard I2C"), regmap-i2c will check the
I2C_FUNC_SMBUS_[BYTE|WORD]_DATA functionality based on the regmap_config
setting if the adapter does not support standard I2C.

So remove the I2C_FUNC_SMBUS_WORD_DATA functionality check in the driver code.

60eb9579c1 adv7842: comment out a table useful for debug
Gcc 6.1 warns about an unused table:

drivers/media/i2c/adv7842.c:2400:27: warning: 'prim_mode_txt' defined but not used [-Wunused-const-variable=]
 static const char * const prim_mode_txt[] = {
                           ^~~~~~~~~~~~~

That seems to be useful for debug, and likely were used before.
While we could simply remove, let's comment it out, for now.

287980e49f remove lots of IS_ERR_VALUE abuses
Most users of IS_ERR_VALUE() in the kernel are wrong, as they
pass an 'int' into a function that takes an 'unsigned long'
argument. This happens to work because the type is sign-extended
on 64-bit architectures before it gets converted into an
unsigned type.

However, anything that passes an 'unsigned short' or 'unsigned int'
argument into IS_ERR_VALUE() is guaranteed to be broken, as are
8-bit integers and types that are wider than 'unsigned long'.

Andrzej Hajda has already fixed a lot of the worst abusers that
were causing actual bugs, but it would be nice to prevent any
users that are not passing 'unsigned long' arguments.

This patch changes all users of IS_ERR_VALUE() that I could find
on 32-bit ARM randconfig builds and x86 allmodconfig. For the
moment, this doesn't change the definition of IS_ERR_VALUE()
because there are probably still architecture specific users
elsewhere.

Almost all the warnings I got are for files that are better off
using 'if (err)' or 'if (err < 0)'.
The only legitimate user I could find that we get a warning for
is the (32-bit only) freescale fman driver, so I did not remove
the IS_ERR_VALUE() there but changed the type to 'unsigned long'.
For 9pfs, I just worked around one user whose calling conventions
are so obscure that I did not dare change the behavior.

I was using this definition for testing:

 #define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \
       unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO))

which ends up making all 16-bit or wider types work correctly with
the most plausible interpretation of what IS_ERR_VALUE() was supposed
to return according to its users, but also causes a compile-time
warning for any users that do not pass an 'unsigned long' argument.

I suggested this approach earlier this year, but back then we ended
up deciding to just fix the users that are obviously broken. After
the initial warning that caused me to get involved in the discussion
(fs/gfs2/dir.c) showed up again in the mainline kernel, Linus
asked me to send the whole thing again.

[ Updated the 9p parts as per Al Viro  - Linus ]

cacdd6a4a8 [media] tvp5150: return I2C write operation failure to callers
The tvp5150_write() function calls i2c_smbus_write_byte_data() that
can fail but does not propagate the error to the caller. Instead it
just prints a debug, so callers can't know if the operation failed.

So change the function to return the error code to the caller so it
knows that the write failed and also print an error instead of just
printing a debug information.

While being there remove the inline keyword from tvp5150_write() to
make it consistent with tvp5150_read() and also because it's called
in a lot of places, so making inline is in fact counter productive
since it makes the kernel image size to be much bigger (~16 KiB).

It's been reported that CJC7113 devices are returning
all 1s when reading register 0:

  "1111111111111111" found @ 0x4a (stk1160)

This new device is apparently compatible with SA7113, so let's
add a quirk to allow its autodetection. Given there isn't
any known differences with SAA7113, this commit does not
introduces a new saa711x_model value.
