the SoC camera framework. Drop support for the default crop rectaingle in

A number of sub-device drivers used a static name for the sub-device, and
thus the media entity. As the entity name must be unique within a media
device, this makes it impossible to have more than one instance of each
device in a media device. This is a rather severe limitation.
Instead of fixing these drivers, add a comment to the drivers noting that
such static names may not be used in the future.
The alternative of fixing the drivers is troublesome as the entity (as
well as sub-device) name is part of the uAPI. Changing that is almost
certain to break something. As these devices are old but no-one has
encountered a problem with the static names, leave it as-is.

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.

As of: commit 476dec012f ("media: ov5640: Add horizontal and vertical

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.

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.

will be cleaned up again on the ov2680 probe function.
This also simplifies the probe function error path since no initialization
