Hi, This is the second version of my attempt at the CEC framework patches. As mentioned in the previous cover letter the original work was done by Hans Verkuil, but he was short of time and the CEC framework was stalled for some time. The original cover letter attached below will surely shed more light on the history of these patches. Thank you very much for your comments to the v1 . It was near the end of the year when I sent the previous version, so I really appreciate your time. Apart from fixes and additions to the documentation this version of the RFC tackles the subject of processing the key down/up from the remote. To make the solution most flexible there are two modes. In the default the mesages related to key presses on the remote are parsed and handled by the CEC framework. In the pass-through mode the key down/up messages are not handled by the CEC framewrok and are passed to the userspace. The mode can be changed by an appropriate ioctl. I would especially welcome comment to the CEC keymap. Best wishes, Kamil Debski Changes since v2 ================ - 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 repied 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.
