Hi, This is the fourth version of the HDMI CEC framework. I would like to thank for all the comments and suggestions to the previous versions of this patch. I believe that the code has matured enough to be tagged as PATCH and not RFC as in previous version. This patchset is base on the linux-next tree. I believe that there will be some comments to it and there will be some things to fix, hence I am sending this version now. The next version with appropriate fixes will be based on the next RC (which I guess will be released soon). The promiscuous mode included in the previous version caused some discussion and I decided to drop it. In my opinion it can be useful for debugging, but on the other hand I believe it can be easily added at a later time, if appropriate. Best wishes, Kamil Debski Changes since v3 ================ - remove the promiscuous mode - rewrite the devicetree patches - fixes, expansion and partial rewrite of the documentation - reorder of API structures and addition of reserved fields - use own struct to report time (32/64 bit safe) - fix of handling events - add cec.h to include/uapi/linux/Kbuild - fixes in the adv76xx driver (add missing methods, change adv7604 to adv76xx) - cleanup of debug messages in s5p-cec driver - remove non necessary claiming of a gpio in the s5p-cec driver - cleanup headers of the s5p-cec driver Changes since v2 ===============- - added promiscuous mode - added new key codes to the input framework - add vendor ID reporting - add the possibility to clear assigned logical addresses - cleanup of the rc cec map Changes since v1 ================ - documentation edited and moved to the Documentation folder - added key up/down message handling - add missing CEC commands to the cec.h file Original cover letter ===================== Hi, The work on a common CEC framework was started over three years ago by Hans Verkuil. Unfortunately the work has stalled. As I have received the task of creating a driver for the CEC interface module present on the Exynos range of SoCs, I got in touch with Hans. He replied that the work stalled due to his lack of time. The driver was done in the most part and there were only minor fixes that needed to be implemented. I would like to bring back the discussion on a common CEC interface framework. There are a few things that were still left as TODO, I think they might need some discussion - for instance the way how the remote controls should be handled. Best wishes, Kamil Debski Original RFC by Hans Verkuil/Martin Bugge ========================================= https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg28735.html Hans Verkuil (4): cec: add HDMI CEC framework v4l2-subdev: add HDMI CEC ops cec: adv7604: add cec support. cec: adv7511: add cec support.
