Instead of selecting single or continuous capture mode based on how many buffers userspace intends to give us select capture mode based on number of free buffers we can allocate to hardware when the stream is started. This change is a prerequisite to enable the driver to switch from continuous to single capture mode (or the other way around) when the driver is stalled by userspace not feeding it buffers as fast as it consumes it.

This only moves whole structs, defines and functions around, no code is changed inside any function. The reason for moving this code around is to prepare for refactoring and fixing of a start/stop stream bug without having to use forward declarations. Signed-off-by:

It's possible to grab frames using only one buffer, this should never have been set to anything else then 1. Signed-off-by:

Use information about pad index when enumerating mbus codes. Signed-off-by:
-
Niklas Söderlund authored
Information about pads will be needed when enumerating the media bus codes in the async complete handler which is run before rvin_v4l2_probe(). Move the pad lookup to the async bound handler so they are available when needed. Signed-off-by:

The pad lookup code can be broken out to increase readability and to reduce code duplication. Signed-off-by:

Niklas Söderlund authored
It makes more sense to store the sink and source pads in struct rvin_graph_entity since that contains other subdevice related information. The data type to store pad information in is unsigned int and not int, change this. While we are at it drop the _idx suffix from the names, this never made sense. Signed-off-by:

The driver supports a single input only, which can be either analog or digital. If the subdevice supports dv_timings_cap the input is digital and the driver should not fill in the standard. Signed-off-by:

Niklas Söderlund authored
The rcar-vin driver only uses one pad, pad number 0. - All v4l2 operations that did not check that the requested operation was for pad 0 have been updated with a check to enforce this. - All v4l2 operations that stored (and later restored) the requested pad before substituting it for the subdevice pad number have been updated to not store the incoming pad and simply restore it to 0 after the subdevice operation is complete.

Use rvin_reset_format() in rvin_s_dv_timings() instead of just resetting a few fields. This fixes an issue where the field format was not properly set after S_DV_TIMINGS. Signed-off-by:
-
Niklas Söderlund authored
These two were forgotten when refactoring the format reset code. If they are not also reset at the same time as width and height the format returned from G_FMT will not match reality. Signed-off-by:

All drivers have been converted from V4L2 OF to V4L2 fwnode. The V4L2 OF framework is now unused. Remove it. Signed-off-by:

Switch users of the v4l2_of_ APIs to the more generic v4l2_fwnode_ APIs. Async OF matching is replaced by fwnode matching and OF matching support is removed. Signed-off-by:

Sakari Ailus authored
Add fwnode matching to complement OF node matching. And fwnode may also be an OF node. Do not enable fwnode matching yet. It will replace OF matching soon. Signed-off-by:
-
Sakari Ailus authored
The fwnode_handle is a more generic way than OF device_node to describe firmware nodes. Instead of the OF API, use more generic fwnode API to obtain the same information. As the V4L2 fwnode support will be required by a small minority of e.g. ACPI based systems (the same might actually go for OF), make this a module instead of embedding it in the videodev module. The origins of the V4L2 fwnode framework is in the V4L2 OF framework. Signed-off-by:

Fix all checkpatch reported issues for: * CHECK: "braces {} should be used on all arms of this statement". * CHECK: "Unbalanced braces around else statement". Make sure all if/else statements are balanced in terms of braces. Most cases in code are, but a few were left unbalanced, so put them all consistent with the recommended style.

Fix style issues reported by checkpatch, affecting whitespace only: * CHECK: "Please don't use multiple blank lines". Two of these still triggering and left untouched because used for separating logical blocks (vars from functions, etc.). * CHECK: "spaces preferred around that '<operator>'". All fixed. * CHECK: "Alignment should match open parenthesis". All fixed except one on line 1161, left untouched for readability. Move towards recommended coding style without compromising readability. Signed-off-by:

These two functions only make the logic in lirc_register_driver() harder to follow. (Note that almost no other driver calls kobject_set_name() on their cdev so I simply removed that part). Signed-off-by:

Always let the kernel decide what minor the lirc chardev gets. Signed-off-by:

David Härdeman authored
Merging the two means that lirc_allocate_buffer() is called before device_add() and cdev_add() which makes more sense. This also simplifies the locking slightly because lirc_allocate_buffer() will always be called with lirc_dev_lock held. Signed-off-by:

Every caller of lirc_register_driver() passes their own fops and there are no users of lirc_dev_fop_write() in the kernel tree. Thus we can make fops mandatory and remove lirc_dev_fop_write(). Signed-off-by:
