Hi Hans, Thank you for your reply. All dongles that we used to work with in Samsung convert CEC protocol to RCP which we get through MHL Sideband Channel. All we can do in the driver is to report RCP messages to user-space. On the RC subsystem: your point is right, which was confirmed by Sean

Re: [PATCH] drm/bridge/sii8620: add remote control support

Hi Maciej, Unfortunately I do not have the MHL spec, but I was wondering what the relationship between RCP and CEC is. CEC has remote control support as well, so is RCP that subset of the CEC specification or is it completely separate? I'm CC-ing Sean Young and the linux-media mailinglist as

[PATCH] drm/bridge/sii8620: add remote control support

MHL specification defines Remote Control Protocol(RCP) to send input events between MHL devices. The driver now recognizes RCP messages and reacts to them by reporting key events to input subsystem, allowing a user to control a device using TV remote control. Signed-off-by: Maciej Purski
