[media] cec: add CEC_CAP_NEEDS_HPD

2017-06-20T09:54:34+00:00

Add a new capability CEC_CAP_NEEDS_HPD. If this capability is set then the hardware can only use CEC if the HDMI Hotplug Detect pin is high. Such hardware cannot handle the corner case in the CEC specification where it is possible to transmit messages even if no hotplug signal is present (needed for some displays that turn off the HPD when in standby, but still have CEC enabled). Typically hardware that needs this capability have the HPD wired to the CEC block, often to a 'power' or 'active' pin. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] cec: add cec_transmit_attempt_done helper function

2017-06-20T09:52:33+00:00

A simpler variant of cec_transmit_done to be used where the HW does just a single attempt at a transmit. So if the status indicates an error, then the corresponding error count will always be 1 and this function figures that out based on the status argument.

[media] cec: add cec_phys_addr_invalidate() helper function

2017-06-20T09:51:58+00:00

Simplifies setting the physical address to CEC_PHYS_ADDR_INVALID. Signed-off-by: Hans Verkuil Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] cec: add cec_s_phys_addr_from_edid helper function

2017-06-20T09:51:21+00:00

This function simplifies the integration of CEC in DRM drivers. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media/cec.h: use IS_REACHABLE instead of IS_ENABLED

2017-06-08T19:52:28+00:00

Fix messages like this: adv7842.c:(.text+0x2edadd): undefined reference to `cec_unregister_adapter' when CEC_CORE=m but the driver including media/cec.h is built-in. In that case the static inlines provided in media/cec.h should be used by that driver.

[media] cec: rename MEDIA_CEC_NOTIFIER to CEC_NOTIFIER

2017-06-04T18:23:35+00:00

This config option is strictly speaking independent of the media subsystem since it can be used by drm as well. Besides, it looks odd when drivers select CEC_CORE and MEDIA_CEC_NOTIFIER, that's inconsistent naming. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] cec.h: merge cec-edid.h into cec.h

2017-04-19T09:53:18+00:00

Drop the separate cec-edid.h header and merge it into cec.h. There was really no need to have a separate header for this. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] cec: Kconfig cleanup

2017-04-19T09:50:52+00:00

The Kconfig options for the CEC subsystem were a bit messy. In addition there were two cec sources (cec-edid.c and cec-notifier.c) that were outside of the media/cec directory, which was weird. Move those sources to media/cec as well. The cec-edid and cec-notifier functionality is now part of the cec module and these are no longer separate modules. Also remove the MEDIA_CEC_EDID config option and include it with the main CEC config option (which defined CEC_EDID anyway). Added static inlines to cec-edid.h for dummy functions when CEC_CORE isn't defined. CEC drivers should now depend on CEC_CORE. CEC drivers that need the cec-notifier functionality must explicitly select CEC_NOTIFIER. The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of CEC_CORE, fix that as well.
