Nathan Chancellor 6107a895e3 media: v4l2-device.h: Explicitly compare grp{id,mask} to zero in v4l2_device macros
[ Upstream commit afb3478162 ]

When building with Clang + -Wtautological-constant-compare, several of
the ivtv and cx18 drivers warn along the lines of:

 drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the
 result of '<<' to a boolean always evaluates to true
 [-Wtautological-constant-compare]
                         cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL,
                                         ^
 drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro
 'CX18_HW_GPIO_RESET_CTRL'
 #define CX18_HW_GPIO_RESET_CTRL         (1 << 6)
                                           ^
 1 warning generated.

This warning happens because the shift operation is implicitly converted
to a boolean in v4l2_device_mask_call_all before being negated. This can
be solved by just comparing the mask result to 0 explicitly so that
there is no boolean conversion. The ultimate goal is to enable
-Wtautological-compare globally because there are several subwarnings
that would be helpful to have.

For visual consistency and avoidance of these warnings in the future,
all of the implicitly boolean conversions in the v4l2_device macros
are converted to explicit ones as well.

Helen Koike 9cbcbfc67b media: v4l2-rect.h: fix v4l2_rect_map_inside() top/left adjustments
commit f51e50db4c upstream.

boundary->width and boundary->height are sizes relative to
boundary->left and boundary->top coordinates, but they were not being
taken into consideration to adjust r->left and r->top, leading to the
following error:

Consider the follow as initial values for boundary and r:

struct v4l2_rect boundary = {
	.left = 100,
	.top = 100,
	.width = 800,
	.height = 600,
}

struct v4l2_rect r = {
	.left = 0,
	.top = 0,
	.width = 1920,
	.height = 960,
}

calling v4l2_rect_map_inside(&r, &boundary) was modifying r to:

r = {
	.left = 0,
	.top = 0,
	.width = 800,
	.height = 600,
}

Which is wrongly outside the boundary rectangle, because:

	v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600
	...
	if (r->left + r->width > boundary->width) // true
		r->left = boundary->width - r->width; // r->left = 800 - 800
	if (r->top + r->height > boundary->height) // true
		r->top = boundary->height - r->height; // r->height = 600 - 600

Fix this by considering top/left coordinates from boundary.

Stateless decoders have different expectations about the
start code that is prepended on H264 slices. Add a
menu control to express the supported start code types
(including no start code).

Drivers are allowed to support only one start code type,
but they can support both too.

Note that this is independent of the H264 decoding mode,
which specifies the granularity of the decoding operations.
Either in frame-based or slice-based mode, this new control
will allow to define the start code expected on H264 slices.

Expose a menu to control the supported decoding modes. Drivers are

To fully specify the decoding operation, we need to introduce
a start_byte_offset, to indicate where slices start.

Sakari Ailus 016413d967 media: v4l2-async: Get fwnode reference when putting it to the notifier's list
The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of
the added fwnode, relying on the caller to handle that instead, in essence
putting the fwnode to be added if there was an error.

As the reference is eventually released during the notifier cleanup, this
is not intuitive nor logical. Improve this by always getting a reference
when the function succeeds, and the caller releasing the reference when it
does not *itself* need it anymore.

Luckily, perhaps, there were just a handful of callers using the function.

Hans Verkuil b48cb35c6a media: cec-notifier: add new notifier functions
In order to support multiple CEC devices for an HDMI connector,
and to support cec_connector_info, drivers should use either a
cec_notifier_conn_(un)register pair of functions (HDMI drivers)
or a cec_notifier_cec_adap_(un)register pair (CEC adapter drivers).

This replaces cec_notifier_get_conn/cec_notifier_put.

For CEC adapters it is also no longer needed to call cec_notifier_register,
cec_register_cec_notifier and cec_notifier_unregister. This is now
all handled internally by the new functions.

Dariusz Marcinkiewicz 32a847f9fa media: cec: add struct cec_connector_info support
Define struct cec_connector_info in media/cec.h and define
CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to
uapi/linux/cec.h.

The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but
cec_allocate_adapter() will remove it again until the public API
for this can be enabled once all drm drivers wire this up correctly.

Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions,
which are needed by drm drivers to fill in the cec_connector info
based on a drm_connector.

The cec_notifier_(un)register and cec_register_cec_notifier
prototypes were moved from cec-notifier.h to cec.h since cec.h no longer
includes cec-notifier.h. These headers included each other before,
which caused various problems.

Due to these changes the seco-cec driver was changed as well: it
should include cec-notifier.h, not cec.h.

Janusz Krzysztofik a8fa55078a media: v4l2-subdev: Verify arguments in v4l2_subdev_call()
Correctness of format type (try or active) and pad number parameters
passed to subdevice operation callbacks is now verified only for IOCTL
calls.  However, those callbacks are also used by drivers, e.g., V4L2
host interfaces.

Since both subdev_do_ioctl() and drivers are using v4l2_subdev_call()
macro while calling subdevice operations, move those parameter checks
from subdev_do_ioctl() to v4l2_subdev_call() so we can avoid taking care
of those checks inside drivers.

Define a wrapper function for each operation callback in scope, then
gather those wrappers in a static v4l2_subdev_ops structure so the
v4l2_subdev_call() macro can find them easy if provided.
