Subject: [PATCHv2 0/6] drm/omap: hdmi: improve hdmi4 CEC, add CEC for hdmi5
Date: Tue, 2 Mar 2021 17:23:57 +0100 [thread overview]
Message-ID: <20210302162403.983585-1-hverkuil-cisco@xs4all.nl> (raw)
This series improves the drm_bridge support for CEC by introducing two
new bridge ops in the first patch, and using those in the second patch.
This makes it possible to call cec_s_conn_info() and set
CEC_CAP_CONNECTOR_INFO for the CEC adapter, so userspace can associate
the CEC adapter with the corresponding DRM connector.
The third patch simplifies CEC physical address handling by using the
cec_s_phys_addr_from_edid helper function that didn't exist when this
code was originally written.
The fourth patch adds the cec clock to ti,omap5-dss.txt.
The fifth patch the missing cec clock to the dra7 and omap5 device tree,
and the last patch adds CEC support to the OMAP5 driver.
Tested with a Pandaboard and a Beagle X15 board.
Regards,
Hans
Changes since v1:
- as per suggestion from Laurent, changed cec_init/exit to
connector_attach/_detach which are just called for all
bridges. The DRM_BRIDGE_OP_CEC was dropped.
- added patch to add the cec clock to ti,omap5-dss.txt
- swapped the order of the last two patches
- incorporated Tomi's suggestions for the hdmi5 CEC support.
