media: cec-notifier: make cec_notifier_get_conn() static

2020-03-20T08:02:45+00:00

This function is no longer used by other drivers, so it can be made static. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec-notifier: rename conn_name to port_name

2020-03-20T08:02:15+00:00

This argument refers to a stable name for an HDMI port, mostly i915 (ACPI) specific. Since we'll be introducing a more generic 'name' argument as well later, rename this now to avoid confusion. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec: remove unused functions

2020-01-08T13:38:06+00:00

Remove several functions that are no longer used now that the conversion of cec drivers to cec_notifier_conn_(un)register() and cec_notifier_cec_adap_(un)register() is complete. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

cec: add cec_adapter to cec_notifier_cec_adap_unregister()

2019-10-07T10:47:43+00:00

It is possible for one HDMI connector to have multiple CEC adapters. The typical real-world scenario is that where one adapter is used when the device is in standby, and one that's better/smarter when the device is powered up. The cec-notifier changes were made with that in mind, but I missed that in order to support this you need to tell cec_notifier_cec_adap_unregister() which adapter you are unregistering from the notifier. Add this additional argument. It is currently unused, but once all drivers use this, the CEC core will be adapted for these use-cases.

media: cec-notifier: add new notifier functions

2019-06-27T11:19:43+00:00

In order to support multiple CEC devices for an HDMI connector, and to support cec_connector_info, drivers should use either a cec_notifier_conn_(un)register pair of functions (HDMI drivers) or a cec_notifier_cec_adap_(un)register pair (CEC adapter drivers). This replaces cec_notifier_get_conn/cec_notifier_put. For CEC adapters it is also no longer needed to call cec_notifier_register, cec_register_cec_notifier and cec_notifier_unregister. This is now all handled internally by the new functions. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec: add struct cec_connector_info support

2019-06-27T11:18:43+00:00

Define struct cec_connector_info in media/cec.h and define CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to uapi/linux/cec.h. The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but cec_allocate_adapter() will remove it again until the public API for this can be enabled once all drm drivers wire this up correctly. Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions, which are needed by drm drivers to fill in the cec_connector info based on a drm_connector. The cec_notifier_(un)register and cec_register_cec_notifier prototypes were moved from cec-notifier.h to cec.h since cec.h no longer includes cec-notifier.h. These headers included each other before, which caused various problems. Due to these changes the seco-cec driver was changed as well: it should include cec-notifier.h, not cec.h.

media: cec-notifier: add cec_notifier_parse_hdmi_phandle helper

2019-04-22T17:09:59+00:00

Add helper function to parse the DT for the hdmi-phandle property and return the corresponding struct device pointer. It takes care to avoid increasing the device refcount since all we need is the device pointer. This pointer is used in the notifier list as a key, but it is never accessed by the CEC driver.

media: cec-notifier: Get notifier by device and connector name

2018-07-13T07:44:16+00:00

In non device-tree world, we can need to get the notifier by the driver name directly and eventually defer probe if not yet created. This patch adds a variant of the get function by using the device name instead and will not create a notifier if not yet created. But the i915 driver exposes at least 2 HDMI connectors, this patch also adds the possibility to add a connector name tied to the notifier device to form a tuple and associate different CEC controllers for each HDMI connectors.
