Subject: [PATCH v7 05/13] media: tvp5150: add input source selection of_graph support
Date: Thu, 15 Aug 2019 13:57:39 +0200 [thread overview]
Message-ID: <20190815115747.24018-6-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20190815115747.24018-1-m.felsch@pengutronix.de>
This patch adds the of_graph support to describe the tvp input connections.
Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result
of discussion [1],[2] the device-tree maps these ports 1:1. Look at the
Documentation for more information. Since the TVP5150 is a converter/bridge
the device-tree must contain at least 1-input and 1-output port. The
mc-connectors and mc-links are only created if the device-tree contains the
corresponding connector nodes. If more than one connector is available the
media_entity_operations.link_setup() callback ensures that only one
connector is active.

Changelog:
[1] https://patchwork.kernel.org/cover/10794703/
[2] https://patchwork.kernel.org/cover/10786553/
v7:
- don't init enum tvp5150_pads with TVP5150_COMPOSITE0 functionality
- break some 80 character limitation to improve readability
- fix comment style -> always start with capital letters and end with dot
- fix some minor style issues
- fix tvp5150_registered error handling
- simplify tvp5150_mc_init
- make connectors static
-> since now only three connectors are possible (as described in DT)
-> drop tvp5150.endpoints storage
-> squash tvp5150_parse_dt and tvp5150_add_of_connectors
- improve tvp5150_parse_dt:
-> make parsing stricter and fix not detected missconfigured dt-data
-> svideo must be connected now to port@[0,1]/endpoint@1
v6:
- fix misspelled comments
- use 'unsigned int' where it's possible
- cleanup ifdef part-2:
* tvp5150_mc_init, tvp5150_add_of_connectors: add surrounding
CONFIG_MEDIA_CONTROLLER if def and stubs to improve quality
- tvp5150_mc_init: uniform interface, use 'struct tvp5150' since all
internal function do this.
- tvp5150_add_of_connectors: call within probe() to make it cleaner
- tvp5150_parse_dt: move local loop vars within the loop.
v5:
- Fixing build deps:
- tvp5150_mc_init: fix CONFIG_MEDIA_CONTROLLER deps
- struct tvp5150: drop CONFIG_MEDIA_CONTROLLER conditional property
includes. This leads into to complex deps for futher development.
- tvp5150_dt_cleanup: enable function only if CONFIG_OF is enabled
- tvp5150_parse_dt: enable function only if CONFIG_OF is enabled
- tvp5150_probe: call tvp5150_dt_cleanup only if CONFIG_OF is enabled
- Simplify link_setup routine:
- use generic connector parsing since both series [1,2] are squashed into
one
- struct tvp5150: drop pads_state and modify_second_link property
due to link_setup() rework.
- tvp5150_link_setup: add more comments
- tvp5150_link_setup: simply the link setup routine a lot. Edit the 2nd
link directly within the driver instead of a recursive media-framework
call (__media_entity_setup_link). This improves the readability and
shrinks the driver code.
- tvp5150_link_setup: disable all active links in case user switches
connectors without disable it first.
- tvp5150_registered: simplify default link enable path due to link_setup()
rework.
- General cleanups
- tvp5150_parse_dt: drop unecessary test
- tvp5150_parse_dt: add err message due to misconfiguration
- tvp5150_parse_dt: make use of V4L2_MBUS_UNKNOWN definition
- s/dev_dbg/dev_dbg_lvl
v4:
- rebase on top of media_tree/master, fix merge conflict due to commit
60359a28d592 ("media: v4l: fwnode: Initialise the V4L2 fwnode endpoints
to zero")
v3:
- probe(): s/err/err_free_v4l2_ctrls
- drop MC dependency for tvp5150_pads
v2:
- adapt commit message
- unify ifdef switches
- rename tvp5150_valid_input -> tvp5150_of_valid_input, to be more precise
- mc: use 2-input and 1-output pad
- mc: link svideo connector to both input pads
- mc: enable/disable svideo links in one go
- mc: change link_setup() behaviour, switch the input src don't require a
explicite disable before.
- mc: rename 'local' media_pad param to tvp5150_pad to avoid confusion
- mc: enable link to the first available connector and set the
corresponding tvp5150 input src per default during registered()
- mc/of: factor out oftree connector allocation
- of: drop svideo dt port
- of: move svideo connector to port@0/endpoint@1
- of: require at least 1-in and 1-out endpoint
