Hans Verkuil 463659a08d media: hdmi.h: rename ADOBE_RGB to OPRGB and ADOBE_YCC to OPYCC
These names have been renamed in the CTA-861 standard due to trademark
issues. Replace them here as well so they are in sync with the standard.

Hans Verkuil db03401824 media: replace ADOBERGB by OPRGB
The CTA-861 standards have been updated to refer to opRGB instead
of AdobeRGB. The official standard is in fact named opRGB, so
switch to that.

The two old defines referring to ADOBERGB in the public API are
put under #ifndef __KERNEL__ and a comment mentions that they are
deprecated.

has resurfaced with gcc-8:

media/imx/imx-media-csi.c:132:48: error: 'upstream_ep.bus.parallel.bus_width' may be used uninitialized in this function [-Werror=maybe-uninitialized]

I spent some more time digging in this time, and think I have a better
fix, bailing out of the function that either initializes or errors
out here, which simplifies the code enough for gcc to figure out
what is going on. The earlier partial workaround can be removed now,
as the new workaround is better.

Hans Verkuil 9cfd2753f8 media: cec/v4l2: move V4L2 specific CEC functions to V4L2
Several CEC functions are actually specific for use with receivers,
i.e. they should be part of the V4L2 subsystem, not CEC.

These functions deal with validating and modifying EDIDs for (HDMI)
receivers, and they do not actually have anything to do with the CEC
subsystem and whether or not CEC is enabled. The problem was that if
the CEC_CORE config option was not set, then these functions would
become stubs, but that's not right: they should always be valid.

So replace the cec_ prefix by v4l2_ and move them to v4l2-dv-timings.c.
Update all drivers that call these accordingly.

This patch, together with the following ones, fixes a

Jacopo Mondi bad1774ed4 media: ov5640: Fix timings setup code
As of: commit 476dec012f ("media: ov5640: Add horizontal and vertical
totals") the timings parameters gets programmed separately from the
static register values array.

When changing capture mode, the vertical and horizontal totals gets
inspected by the set_mode_exposure_calc() functions, and only later
programmed with the new values. This means exposure, light banding
filter and shutter gain are calculated using the previous timings, and
are thus not correct.

Fix this by programming timings right after the static register value
table has been sent to the sensor in the ov5640_load_regs() function.

Jacopo Mondi aa4bb8b883 media: ov5640: Re-work MIPI startup sequence
Rework the MIPI interface startup sequence with the following changes:

- Remove MIPI bus initialization from the initial settings blob
- At set_power(1) time power up MIPI Tx/Rx and set data and clock lanes in
  LP11 during 'sleep' and 'idle' with MIPI clock in non-continuous mode.
- At s_stream time enable/disable the MIPI interface output.
- Restore default settings at set_power(0) time.

Before this commit the sensor MIPI interface was initialized with settings
that require a start/stop sequence at power-up time in order to force lanes
into LP11 state, as they were initialized in LP00 when in 'sleep mode',
which is assumed to be the sensor manual definition for the D-PHY defined
stop mode.

The stream start/stop was performed by enabling disabling clock gating,
and had the side effect to change the lanes sleep mode configuration when
stream was stopped.

Clock gating/ungating:
-       ret = ov5640_mod_reg(sensor, OV5640_REG_MIPI_CTRL00, BIT(5),
-                            on ? 0 : BIT(5));
-       if (ret)

Set lanes in LP11 when in 'sleep mode':
-       ret = ov5640_write_reg(sensor, OV5640_REG_PAD_OUTPUT00,
-                              on ? 0x00 : 0x70);

This commit fixes an issue reported by Jagan Teki on i.MX6 platforms that
prevents the host interface from powering up correctly:
https://lkml.org/lkml/2018/6/1/38

It also improves MIPI capture operations stability on my testing platform
where MIPI capture often failed and returned all-purple frames.

The driver registers the v4l2 subdevice before attempting to power on the

waiting for this subdevice to be bound, will prematurely expose its media
device node to userspace because if something goes wrong the media entity
will be cleaned up again on the ov2680 probe function.

This also simplifies the probe function error path since no initialization
is made before attempting to enable the resources or checking the chip ID.

Luca Ceresoli 7d2332c76d media: imx274: rearrange sensor startup register tables
Rearrange the imx274_start_<N> register tables to better match the
datasheet and slightly simplify code:

 - collapes tables 1 and 2, they are applied one after each other and
   together they implement the fixed part 1 of the startup procedure
   in the datasheet
 - while there, cleanup comments
 - rename tables 3 and 4 -> 2 and 3, coherently with the datasheet

The UDS is currently restricted based on a partition size of 256 pixels.
Document the actual restrictions, but don't increase the implementation.

The extended partition algorithm may later choose to utilise a larger
partition size to support overlapping partitions which will improve the
quality of the output images.

The LIF module has a data buffer to accommodate clock rate differences
between the DU and the VSP. Several programmable threshold values
