In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

| * | [media] media: Rename graph and pipeline structs and functionsSakari Ailus2017-01-271-9/+9
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The media_entity_pipeline_start() and media_entity_pipeline_stop() functions are renamed as media_pipeline_start() and media_pipeline_stop(), respectively. The reason is two-fold: the pipeline struct is, rightly, already called media_pipeline (rather than media_entity_pipeline) and what this really is about is a pipeline. A pipeline consists of entities --- and, well, other objects embedded in these entities. As the pipeline object will be in the future moved from entities to pads in order to support multiple pipelines through a single entity, do the renaming now. Similarly, functions operating on struct media_entity_graph as well as the struct itself are renamed by dropping the "entity_" part from the prefix of the function family and the data structure. The graph traversal which is what the functions are about is not specifically about entities only and will operate on pads for the same reason as the media pipeline. The patch has been generated using the following command: git grep -l media_entity |xargs perl -i -pe ' s/media_entity_pipeline/media_pipeline/g; s/media_entity_graph/media_graph/g' And a few manual edits related to line start alignment and line wrapping.

* | [media] videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGBHans Verkuil2017-02-131-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts 'commit 7e0739cd9c40 ("[media] videodev2.h: fix sYCC/AdobeYCC default quantization range"). The problem is that many drivers can convert R'G'B' content (often from sensors) to Y'CbCr, but they all produce limited range Y'CbCr. To stay backwards compatible the default quantization range for sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full range, even though the corresponding standards specify full range. Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and also update the documentation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CEC_MSG_INITIATE_ARC message is special since it is the ONLY CEC message that accepts two possible valid replies: CEC_MSG_REPORT_ARC_INITIATED and CEC_MSG_REPORT_ARC_TERMINATED. So if the transmitted message is CEC_MSG_INITIATE_ARC and the remote side replied with CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED, then a msg->reply value of CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED will match either reply. I thought about either adding a second reply2 field, but that's ugly for all other messages that have only one reply, and what if in the future a new message is added that can have three replies? Another option would be to add a cec_msg flag, but really, the combination of CEC_MSG_REPORT_ARC_INITIATED and a reply value of one of the two possible replies already functions as a flag. Another advantage of this approach is that it is safe to re-use a cec_msg struct. No need to zero a flags field or a reply2 field. So since this really is an exception in the CEC specification, I decided to implement it as an exception as well.

This used to be the default behavior, but now you have to explicitly enable it. This is done to force the caller to think about possible security issues (e.g. if these messages are used to enter passwords).
