commit bfcba38d95a0aed146a958a84a2177af1459eddc upstream.
v4l2_ctrl_handler_free() uses hdl->lock, which in ov5640 driver is set
to sensor's own sensor->lock. In ov5640_remove(), the driver destroys the
sensor->lock first, and then calls v4l2_ctrl_handler_free(), resulting
in the use of the destroyed mutex.
Fix this by calling moving the mutex_destroy() to the end of the cleanup
sequence, as there's no need to destroy the mutex as early as possible.

commit 5c49ac3ac6562a39baa2aece050a14b661197036 upstream.
Commit c62b96050bee ("media: ov6650: Register with asynchronous
subdevice framework") carelessly requested creation of a video device
node by setting a V4L2_SUBDEV_FL_HAS_DEVNODE flag. The driver is not
ready for that as it doesn't implement proper locking required for
serialization of IOCTLs.
Fix it by dropping the flag assignment.

commit f1a64f56663e9d03e509439016dcbddd0166b2da upstream.
From the measured hardware signal, OV5695 reset pin goes high for a
short period of time during boot-up. From the sensor specification, the
reset pin is active low and the DT binding defines the pin as active
low, which means that the values set by the driver are inverted and thus
the value requested in probe ends up high.
Fix it by changing probe to request the reset GPIO initialized to high,
which makes the initial state of the physical signal low.
In addition, DOVDD rising must occur before DVDD rising from spec., but
regulator_bulk_enable() API enables all the regulators asynchronously.
Use an explicit loops of regulator_enable() instead.
For power off sequence, it is required that DVDD falls first. Given the
bulk API does not give any guarantee about the order of regulators,
change the driver to use regulator_disable() instead.
The sensor also requires a delay between reset high and first I2C
transaction, which was assumed to be 8192 XVCLK cycles, but 1ms is
recommended by the vendor. Fix this as well.

commit 1451d5ae351d938a0ab1677498c893f17b9ee21d upstream.
This driver supports both the mt9v032 (color) and the mt9v022 (mono)
sensors. Depending on which sensor is used, the format from the sensor is
different. The format.code inside the dev struct holds this information.
The enum mbus and enum frame sizes need to take into account both type of
sensors, not just the color one. To solve this, use the format.code in
these functions instead of the hardcoded bayer color format (which is only
used for mt9v032).

commit 2e3df204f9af42a47823ee955c08950373417420 upstream.
The variable _rate is by ov5640_compute_sys_clk() which returns
zero if the PLL exceeds 1GHz. Unfortunately, the check to see
if the max PLL1 output is checking 'rate' and not '_rate' and
'rate' does not ever appear to be 0.
This patch changes the check against the returned value of
'_rate' to determine if the PLL1 output exceeds 1GHz.

commit 5439fa9263cb293e41168bc03711ec18c4f11cba upstream.
It is not clear what pixel format is actually configured in hardware on
reset. MEDIA_BUS_FMT_YUYV8_2X8, assumed on device probe since the
driver was intiially submitted, is for sure not the one.
Fix it by explicitly applying a known, driver default frame format just
after initial device reset.

commit 39034bb0c26b76a2c3abc54aa28c185f18b40c2f upstream.
Commit da298c6d98d5 ("[media] v4l2: replace video op g_mbus_fmt by pad
op get_fmt") converted a former ov6650_g_fmt() video operation callback
to an ov6650_get_fmt() pad operation callback. However, the converted
function disregards a format->which flag that pad operations should
obey and always returns active frame format settings.
That can be fixed by always responding to V4L2_SUBDEV_FORMAT_TRY with
-EINVAL, or providing the response from a pad config argument, likely
updated by a former user call to V4L2_SUBDEV_FORMAT_TRY .set_fmt().
Since implementation of the latter is trivial, go for it.

commit 1c6a2b63095154bbf9e8f38d79487a728331bf65 upstream.
User arguments passed to .get/set_fmt() pad operation callbacks may
contain unsupported values. The driver takes control over frame size
and pixel code as well as colorspace and field attributes but has never
cared for remainig format attributes, i.e., ycbcr_enc, quantization
and xfer_func, introduced by commit 11ff030c7365 ("[media]
v4l2-mediabus: improve colorspace support"). Fix it.
Set up a static v4l2_mbus_framefmt structure with attributes
initialized to reasonable defaults and use it for updating content of
user provided arguments. In case of V4L2_SUBDEV_FORMAT_ACTIVE,
postpone frame size update, now performed from inside ov6650_s_fmt()
helper, util the user argument is first updated in ov6650_set_fmt() with
default frame format content. For V4L2_SUBDEV_FORMAT_TRY, don't copy
all attributes to pad config, only those handled by the driver, then
fill the response with the default frame format updated with resulting
pad config format code and frame size.

commit 57822068dd120386b98891cb151dc20107b63ba7 upstream.
The driver stores a frame interval value supposed to be in line with
hardware state in a device private structure. Since the driver initial
submission, the respective field of the structure has never been
initialised on device probe. Moreover, if updated from
.s_frame_interval(), a new value is stored before it is applied on
hardware. If an error occurs during device update, the stored value
may no longer reflect hardware state and consecutive calls to
.g_frame_interval() may return incorrect information.
Assuming a failed update of the device means its actual state hasn't
changed, update the frame interval field of the device private
structure with a new value only after it is successfully applied on
hardware so it always reflects actual hardware state to the extent
possible. Also, initialise the field with hardware default frame
interval on device probe.

commit 1463b371aff0682c70141f7521db13cc4bbf3016 upstream.
The driver stores crop rectangle settings supposed to be in line with
hardware state in a device private structure. Since the driver initial
submission, crop rectangle width and height settings are not updated
correctly when rectangle offset settings are applied on hardware. If
an error occurs while the device is updated, the stored settings my no
longer reflect hardware state and consecutive calls to .get_selection()
as well as .get/set_fmt() may return incorrect information. That in
turn may affect ability of a bridge device to use correct DMA transfer
settings if such incorrect informamtion on active frame format returned
by .get/set_fmt() is used.
Assuming a failed update of the device means its actual settings haven't
changed, update crop rectangle width and height settings stored in the
device private structure correctly while the rectangle offset is
successfully applied on hardware so the stored values always reflect
actual hardware state to the extent possible.

commit 7b188d6ba27a131e7934a51a14ece331c0491f18 upstream.
Commit 4f996594ceaf ("[media] v4l2: make vidioc_s_crop const")
introduced a writable copy of constified user requested crop rectangle
in order to be able to perform hardware alignments on it. Later
on, commit 10d5509c8d50 ("[media] v4l2: remove g/s_crop from video
ops") replaced s_crop() video operation using that const argument with
set_selection() pad operation which had a corresponding argument not
constified, however the original behavior of the driver was not
restored. Since that time, any hardware alignment applied on a user
requested crop rectangle is not passed back to the user calling
.set_selection() as it should be.
Fix the issue by dropping the copy and replacing all references to it
with references to the crop rectangle embedded in the user argument.

Prevent mangling with gains with invalid values.
As pointed by Sylvester, this should never happen in practice,
as min value of V4L2_CID_GAIN control is 16 (gain is always >= 16
and m is always >= 0), but it is too hard for a static analyzer
to get this, as the logic with validates control min/max is

commit aa4bb8b8838ffcc776a79f49a4d7476b82405349
Author: Jacopo Mondi <jacopo@jmondi.org>
Date: Fri Jul 6 05:51:52 2018 -0400
media: ov5640: Re-work MIPI startup sequence
In the OV5645 case, the changes are:
- 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 set_power(0) time power down MIPI Tx/Rx (in addition to the current
power down of regulators and clock gating).
- At s_stream time enable/disable the MIPI interface output.
With this commit the sensor is able to enter LP-11 mode during power up,
as expected by some CSI-2 controllers.
Many thanks to Fabio Estevam for his help debugging this issue.

[ Upstream commit b2ce5617dad254230551feda3599f2cc68e53ad8 ]
When building with CONFIG_VIDEO_ADV7511 and CONFIG_DRM_I2C_ADV7511
enabled as loadable modules, we see the following warning:
drivers/gpu/drm/bridge/adv7511/adv7511.ko
drivers/media/i2c/adv7511.ko
Rework so that the file is named adv7511-v4l2.c.

[ Upstream commit 6e4ab830ac6d6a0d7cd7f87dc5d6536369bf24a8 ]
If the requested framesize by VIDIOC_SUBDEV_S_FMT is larger than supported
framesizes, it causes an out of bounds array access and the resulting
framesize is unexpected.
Avoid out of bounds array access and select the default framesize.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

This driver returns an error if unsupported media bus pixel code is
requested by VIDIOC_SUBDEV_S_FMT.
But according to Documentation/media/uapi/v4l/vidioc-subdev-g-fmt.rst,
Drivers must not return an error solely because the requested format
doesn't match the device capabilities. They must instead modify the
format to match what the hardware can provide.
So select default format code and return success in that case.
This is detected by v4l2-compliance.

In preparation for adding asynchronous subdevice support to the driver,
don't acquire v4l2_clk from the driver .probe() callback as that may
fail if the clock is provided by a bridge driver which may be not yet
initialized. Move the v4l2_clk_get() to ov6650_video_probe() helper
which is going to be converted to v4l2_subdev_internal_ops.registered()
callback, executed only when the bridge driver is ready.

After removal of clock_start() from before soc_camera_init_i2c() in
soc_camera_probe() by commit 9aea470b399d ("[media] soc-camera: switch
I2C subdevice drivers to use v4l2-clk") introduced in v3.11, the ov6650
driver could no longer probe the sensor successfully because its clock
was no longer turned on in advance. The issue was initially worked
around by adding that missing clock_start() equivalent to OMAP1 camera
interface driver - the only user of this sensor - but a propoer fix
should be rather implemented in the sensor driver code itself.
Fix the issue by inserting a delay between the clock is turned on and
the sensor I2C registers are read for the first time.
Tested on Amstrad Delta with now out of tree but still locally
maintained omap1_camera host driver.

The exposure control is clustered with the autoexposure control and
flagged as volatile, but the g_volatile_ctrl() doesn't handle
V4L2_CID_EXPOSURE_AUTO. So, the value of the exposure control can't be
read in autoexposure mode.
This enables to get the exposure control in autoexposure mode by making
ov7740_get_volatile_ctrl() deal with V4L2_CID_EXPOSURE_AUTO.
This also sets the exposure control as volatile by specifying the
argument to v4l2_ctrl_auto_cluster() instead of manually flagging it.

As warned by smatch:
drivers/media/i2c/imx214.c:591 imx214_set_format() warn: variable dereferenced before check 'format' (see line 589)
It turns that the code at imx214_set_format() has support for being
called with the format being NULL. I've no idea why, as it is only
called internally with the pointer set, and via subdev API (with
should also set it).
Also, the entire logic there depends on having format != NULL, so
just remove the bogus broken support for a null format.
