g_volatile_ctrl() in manual mode in order to get the manual initial value.

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.

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
chip and checking its ID. This means that a media device driver that it's
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.

Currently this driver does not support cropping. The supported modes
are the following, all capturing the entire area:
- 3840x2160, 1:1 binning (native sensor resolution)
- 1920x1080, 2:1 binning
- 1280x720, 3:1 binning
The VIDIOC_SUBDEV_S_FMT ioctl chooses among these 3 configurations the
one that matches the requested format.
Add cropping support via VIDIOC_SUBDEV_S_SELECTION: with target
V4L2_SEL_TGT_CROP to choose the captured area, with
V4L2_SEL_TGT_COMPOSE to choose the output resolution.
To maintain backward compatibility we also allow setting the compose
format via VIDIOC_SUBDEV_S_FMT. To obtain this, compose rect and
output format are computed in the common helper function
__imx274_change_compose(), which sets both to the same width/height
values.
Cropping also calls __imx274_change_compose() whenever cropping rect
size changes in order to reset the compose rect (and output format
size) for 1:1 binning.
Also rename enum imx274_mode to imx274_binning (and its values from
IMX274_MODE_BINNING_* to IMX274_BINNING_*). Without cropping, the two
naming are equivalent. With cropping, the resolution could be
different, e.g. using 2:1 binning mode to crop 1200x960 and output a
600x480 format. Using binning in the names avoids any

Currently 2-bytes and 3-bytes registers are set by very similar
functions doing the needed shift & mask manipulation, followed by very
similar for loops setting one byte at a time over I2C.
Replace all of this code by a unique helper function that calls
regmap_bulk_write(), which has two advantages:
- sets all the bytes in a unique I2C transaction
- removes lots of now unused code.

Instead use 'DV' (Digital Video), which nicely corresponds to the

We keep an alias to avoid breaking userspace applications.
Since this alias is only available if __KERNEL__ is *not* defined

Data about the implemented readout modes is partially stored in
imx274_formats[], the rest is scattered in several arrays. The latter
are then accessed using the mode index, e.g.:
min_frame_len[priv->mode_index]
Consolidate all these data in imx274_formats[], and store a pointer to
the selected mode (i.e. imx274_formats[priv->mode_index]) in the main
device struct. This way code to use these data becomes more readable,
e.g.:
priv->mode->min_frame_len
This removes lots of scaffolding code and keeps data about each mode
in a unique place.
Also remove a parameter to imx274_mode_regs() that is now unused.
While this adds the mode pointer to the device struct, it does not
remove the mode_index from it because mode_index is still used in two
dev_dbg() calls. This will be handled in a follow-up commit.

The current probe function calls v4l2_ctrl_handler_setup() before
initializing the format info. This triggers call paths such as:
imx274_probe -> v4l2_ctrl_handler_setup -> imx274_s_ctrl ->
imx274_set_exposure, where priv->mode_index is accessed before being
assigned.
This is wrong but does not trigger a visible bug because priv is
zero-initialized and 0 is the default value for priv->mode_index. But
this would become a crash in follow-up commits when mode_index is
replaced by a pointer that must always be valid.
Fix the bug before it shows up by initializing struct members early.

Add a v4l2 sub-device driver for the ak7375 lens voice coil.
This is a voice coil module using the i2c bus to control the
focus position.
ak7375 can write multiple bytes of data at a time. If more
data is received instead of the stop condition after receiving
one byte of data, the address inside the chip is automatically
incremented and the data is written into the next address.
The ak7375 can control the position with 12 bits value and
consists of two 8 bit registers show as below:
register 0x00(AK7375_REG_POSITION):
+---+---+---+---+---+---+---+---+
|D11|D10|D09|D08|D07|D06|D05|D04|
+---+---+---+---+---+---+---+---+
register 0x01:
+---+---+---+---+---+---+---+---+
|D03|D02|D01|D00|---|---|---|---|
+---+---+---+---+---+---+---+---+
This driver support :
- set ak7375 to standby mode once suspend and
turn it back to active if resume
- set the position via V4L2_CID_FOCUS_ABSOLUTE ctrl

The banding filter ON/OFF is controlled via bit 5 of COM8 register. It
is attempted to be enabled in ov772x_set_params() by the following line.
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, 1);
But this unexpectedly results disabling the banding filter, because the
mask and set bits are exclusive.
On the other hand, ov772x_s_ctrl() correctly sets the bit by:
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, BNDF_ON_OFF);
The same fix was already applied to non-soc_camera version of ov772x

We don't need to keep track of the current value by ourself, if we use

This is a preparatory change to avoid accessing registers under power
