512fc4d735 media: ov13b10: Enable runtime PM before registering async sub-device
[ Upstream commit 7b0454cfd8 ]

As the sensor device maybe accessible right after its async sub-device is
registered, such as ipu-bridge will try to power up sensor by sensor's
client device's runtime PM from the async notifier callback, if runtime PM
is not enabled, it will fail.

So runtime PM should be ready before its async sub-device is registered
and accessible by others.

9b1c0aca7f media: ov5640: Drop dead code using frame_interval
[ Upstream commit eeaa47d182 ]

The ov5640_update_pixel_rate() function handles the parallel and MIPI
CSI-2 cases separately.

When running on a parallel setup the V4L2_CID_PIXEL_RATE value is
calculated at the beginning of the function using the values configured
with the frame_interval operations, and then the function immediately
returns.

The remaining of the function handles the MIPI CSI-2 configuration and
should not use the 'current_fr' and 'def_fps' fields as those are only
relevant for parallel mode.

Drop a small section of dead code that updates vblank using
frame_interval on a MIPI CSI-2 setup.

Select V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API for all sensor drivers. This
also adds the options to drivers that don't specifically need them, these
are still seldom used drivers using old APIs. The upside is that these
should now all compile --- many drivers have had missing dependencies.

The "menu" is replaced by selectable "menuconfig" to select the needed
V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API options.

Also select MEDIA_CONTROLLER which VIDEO_V4L2_SUBDEV_API effectively
depends on, and add the I2C dependency to the menu.

85fb0b963f media: ov2680: Fix ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY not working
[ Upstream commit c0e97a4b4f ]

ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY was getting
the try_fmt v4l2_mbus_framefmt struct from the passed in sd_state
and then storing the contents of that into the return by reference
format->format struct.

While the right thing to do would be filling format->format based on
the just looked up mode and then store the results of that in
sd_state->pads[0].try_fmt .

Before the previous change introducing ov2680_fill_format() this
resulted in ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY always
returning the zero-ed out sd_state->pads[0].try_fmt in format->format
breaking callers using this.

After the introduction of ov2680_fill_format() which at least
initializes sd_state->pads[0].try_fmt properly, format->format
is now always being filled with the default 800x600 mode set by
ov2680_init_cfg() independent of the actual requested mode.

Move the filling of format->format with ov2680_fill_format() to
before the if (which == V4L2_SUBDEV_FORMAT_TRY) and then store
the filled in format->format in sd_state->pads[0].try_fmt to
fix this.

Note this removes the fmt local variable because IMHO having a local
variable which points to a sub-struct of one of the function arguments
just leads to confusion when reading the code.

This is a preparation patch for fixing ov2680_set_fmt()

Note that for ov2680_init_cfg() this now simply always fills

ov2680_init_cfg() is never called with a NULL sd_state so the old
sd_state check is not necessary.

7263c39fd7 media: ov2680: Fix ov2680_bayer_order()
[ Upstream commit 50a7bad4e0 ]

The index into ov2680_hv_flip_bayer_order[] should be 0-3, but
ov2680_bayer_order() was using 0 + BIT(2) + (BIT(2) << 1) as
max index, while the intention was to use: 0 + 1 + 2 as max index.

Fix the index calculation in ov2680_bayer_order(), while at it
also just use the ctrl values rather then reading them back using
a slow i2c-read transaction.

This also allows making the function void, since there now are
no more i2c-reads to error check.

Note the check for the ctrls being NULL is there to allow
adding an ov2680_fill_format() helper later, which will call
ov2680_set_bayer_order() during probe() before the ctrls are created.

ef9055e9a7 media: ov2680: Remove auto-gain and auto-exposure controls
[ Upstream commit 7b5a42e6ae ]

Quoting the OV2680 datasheet:

"3.2 exposure and gain control

In the OV2680, the exposure time and gain are set manually from an external
controller. The OV2680 supports manual gain and exposure control only for
normal applications, no auto mode."

And indeed testing with the atomisp_ov2680 fork of ov2680.c has shown that
auto-exposure and auto-gain do not work.

Note that the code setting the auto-exposure flag was broken, callers
of ov2680_exposure_set() were directly passing !!ctrls->auto_exp->val as
"bool auto_exp" value, but ctrls->auto_exp is a menu control with:

enum  v4l2_exposure_auto_type {
        V4L2_EXPOSURE_AUTO = 0,
        V4L2_EXPOSURE_MANUAL = 1,
	...

So instead of passing !!ctrls->auto_exp->val they should have been passing
ctrls->auto_exp->val == V4L2_EXPOSURE_AUTO, iow the passed value was
inverted of what it should have been.

Also remove ov2680_g_volatile_ctrl() since without auto support the gain
and exposure controls are not volatile.

This also fixes the control values not being properly applied in
ov2680_mode_set(). The 800x600 mode register-list also sets gain,
exposure and vflip overriding the last set ctrl values.

ov2680_mode_set() does call ov2680_gain_set() and ov2680_exposure_set()
but did this before writing the mode register-list, so these values
would still be overridden by the mode register-list.

Add a v4l2_ctrl_handler_setup() call after writing the mode register-list
to restore all ctrl values. Also remove the ctrls->gain->is_new check from
ov2680_gain_set() so that the gain always gets restored properly.

Last since ov2680_mode_set() now calls v4l2_ctrl_handler_setup(), remove
the v4l2_ctrl_handler_setup() call after ov2680_mode_restore() since
ov2680_mode_restore() calls ov2680_mode_set().

2b9d0a65d1 media: ov5640: Fix initial RESETB state and annotate timings
[ Upstream commit a210df337c ]

The initial state of RESETB input signal of OV5640 should be
asserted, i.e. the sensor should be in reset. This is not the
case, make it so.

Since the subsequent assertion of RESETB signal is no longer
necessary and the timing of the power sequencing could be
slightly adjusted, add annotations to the delays which match
OV5640 datasheet rev. 2.03, both:
  figure 2-3 power up timing with internal DVDD
  figure 2-4 power up timing with external DVDD source

The 5..10ms delay between PWDN assertion and RESETB assertion
is not even documented in the power sequencing diagram, and
with this reset fix, it is no longer even necessary.

Set OV5640_REG_IO_MIPI_CTRL00 bit 2 to 1 instead of 0, since 1 means
MIPI CSI2 interface, while 0 means CPI parallel interface.

In the ov5640_set_power_mipi() the interface should obviously be set
to MIPI CSI2 since this functions is used to power up the sensor when
operated in MIPI CSI2 mode. The sensor should not be in CPI mode in
that case.

This fixes a corner case where capturing the first frame on i.MX8MN

[ Upstream commit f126ff7e40 ]

The supported ad5820 and ad5821 VCMs both use a single 16 bit register
which is written by sending 2 bytes with the data directly after sending
the i2c-client address.

The ad5823 OTOH has a more typical i2c / smbus device setup with multiple
8 bit registers where the first byte send after the i2c-client address is
the register address and the actual data only starts from the second byte
after the i2c-client address.

The ad5823 i2c_ and of_device_id-s was added at the same time as
the ad5821 ids with as rationale:

"""
Some camera modules also refer that AD5823 is a replacement of AD5820:
https://download.kamami.com/p564094-OV8865_DS.pdf
"""

The AD5823 may be an electrical and functional replacement of the AD5820,
but from a software pov it is not compatible at all and it is going to
need its own driver, drop its id from the ad5820 driver.

[ Upstream commit a828002f38 ]

OV5640 will output abnormal image data when work at low resolution
(320x240, 176x144 and 160x120) after switching from high resolution,
such as 1080P, the time interval between high and low switching must
be less than 1000ms in order to OV5640 don't enter suspend state during
the time.

The reason is by 0x3824 value don't restore to initialize value when
do resolution switching. In high resolution setting array, 0x3824 is
set to 0x04, but low resolution setting array remove 0x3824 in commit
db15c1957a ("media: ov5640: Remove duplicated mode settings"). So
when do resolution switching from high to low, such as 1080P to 320x240,
and the time interval is less than auto suspend delay time which means
global initialize setting array will not be loaded, the output image
data are abnormal. Hence move 0x3824 from ov5640_init_setting[] table
to ov5640_setting_low_res[] table and also move 0x4407 0x460b, 0x460c
to avoid same issue.

It the device is probed in non-zero ACPI D state, the module
identification is delayed until the first streamon.

The module identification has two parts: deviceID and version. To rea
the version we have to enable OTP read. This cannot be done during
streamon, becase it modifies REG_MODE_SELECT.

Since the driver has the same behaviour for all the module versions, do
not read the module version from the sensor's OTP.

a2b8a41cc9 media: m5mols: fix off-by-one loop termination error
[ Upstream commit efbcbb12ee ]

The __find_restype() function loops over the m5mols_default_ffmt[]
array, and the termination condition ends up being wrong: instead of
stopping when the iterator becomes the size of the array it traverses,
it stops after it has already overshot the array.

Now, in practice this doesn't likely matter, because the code will
always find the entry it looks for, and will thus return early and never
hit that last extra iteration.

But it turns out that clang will unroll the loop fully, because it has
only two iterations (well, three due to the off-by-one bug), and then
clang will end up just giving up in the middle of the loop unrolling
when it notices that the code walks past the end of the array.

And that made 'objtool' very unhappy indeed, because the generated code
just falls off the edge of the universe, and ends up falling through to
the next function, causing this warning:

   drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc()

Fix the loop ending condition.

39111cedd7 media: ov5640: Fix analogue gain control
[ Upstream commit afa4805799 ]

Gain control is badly documented in publicly available (including
leaked) documentation.

There is an AGC pre-gain in register 0x3a13, expressed as a 6-bit value
(plus an enable bit in bit 6). The driver hardcodes it to 0x43, which
one application note states is equal to x1.047. The documentation also
states that 0x40 is equel to x1.000. The pre-gain thus seems to be
expressed as in 1/64 increments, and thus ranges from x1.00 to x1.984.
What the pre-gain does is however unspecified.

There is then an AGC gain limit, in registers 0x3a18 and 0x3a19,
expressed as a 10-bit "real gain format" value. One application note
sets it to 0x00f8 and states it is equal to x15.5, so it appears to be
expressed in 1/16 increments, up to x63.9375.

The manual gain is stored in registers 0x350a and 0x350b, also as a
10-bit "real gain format" value. It is documented in the application
note as a Q6.4 values, up to x63.9375.

One version of the datasheet indicates that the sensor supports a
digital gain:

  The OV5640 supports 1/2/4 digital gain. Normally, the gain is
  controlled automatically by the automatic gain control (AGC) block.

It isn't clear how that would be controlled manually.

There appears to be no indication regarding whether the gain controlled
through registers 0x350a and 0x350b is an analogue gain only or also
includes digital gain. The words "real gain" don't necessarily mean
"combined analogue and digital gains". Some OmniVision sensors (such as
the OV8858) are documented as supoprting different formats for the gain
values, selectable through a register bit, and they are called "real
gain format" and "sensor gain format". For that sensor, we have (one of)
the gain registers documented as

  0x3503[2]=0, gain[7:0] is real gain format, where low 4 bits are
  fraction bits, for example, 0x10 is 1x gain, 0x28 is 2.5x gain

  If 0x3503[2]=1, gain[7:0] is sensor gain format, gain[7:4] is coarse
  gain, 00000: 1x, 00001: 2x, 00011: 4x, 00111: 8x, gain[7] is 1,
  gain[3:0] is fine gain. For example, 0x10 is 1x gain, 0x30 is 2x gain,
  0x70 is 4x gain

(The second part of the text makes little sense)

"Real gain" may thus refer to the combination of the coarse and fine
analogue gains as a single value.

The OV5640 0x350a and 0x350b registers thus appear to control analogue
gain. The driver incorrectly uses V4L2_CID_GAIN as V4L2 has a specific
control for analogue gain, V4L2_CID_ANALOGUE_GAIN. Use it.

If registers 0x350a and 0x350b are later found to control digital gain
as well, the driver could then restrict the range of the analogue gain
control value to lower than x64 and add a separate digital gain control.

2x2 binning works fine for RAW10 capture, but for RAW8 1232p mode it
leads to corrupted frames [1][2].

Using the special 2x2 analog binning mode fixes the issue, but causes
artefacts for RAW10 1232p capture. So here we choose the binning mode
depending upon the frame format selected.

As both binning modes work fine for 480p RAW8 and RAW10 capture, it can
share the same code path as 1232p for selecting binning mode.

a40d94f0b3 media: ov5640: Handle delays when no reset_gpio set
[ Upstream commit d7ff691399 ]

Some module manufacturers [1][2] don't expose the RESETB and PWDN pins
of the sensor directly through the 15-pin FFC connector. Instead wiring
~PWDN gpio to the sensor pins with appropriate delays.

In such cases, reset_gpio will not be available to the driver, but it
will still be toggled when the sensor is powered on, and thus we should
still honor the wait time of >= 5ms + 1ms + 20ms (see figure 2-3 in [3])
before attempting any i/o operations over SCCB.

Also, rename the function to ov5640_powerup_sequence to better match the
datasheet (section 2.7).

8064bbb754 media: ov5640: Fix soft reset sequence and timings
[ Upstream commit decea0a98b ]

Move the register-based reset out of the init_setting[] and into the
powerup_sequence function. The sensor is power cycled and reset using
the gpio pins so the soft reset is not always necessary.

This also ensures that soft reset honors the timing sequence
from the datasheet [1].

d6ebcae042 media: mt9p031: Drop bogus v4l2_subdev_get_try_crop() call from mt9p031_init_cfg()
[ Upstream commit e208ad015f ]

The mt9p031_init_cfg() already calls __mt9p031_get_pad_crop(), which
correctly calls v4l2_subdev_get_try_crop() on V4L2_SUBDEV_FORMAT_TRY
or returns &mt9p031->crop on V4L2_SUBDEV_FORMAT_ACTIVE. No need to
call v4l2_subdev_get_try_crop() in mt9p031_init_cfg() again in case
of both V4L2_SUBDEV_FORMAT_TRY and V4L2_SUBDEV_FORMAT_ACTIVE.

This also fixes a splat generated by this call since commit
2ba3e38517 ("media: v4l: subdev: Fail graciously when getting try data for NULL state")
because v4l2_subdev_get_try_crop() is called with sd_state = NULL
in mt9p031_init_cfg().
