[PATCH v10 0/9] Register Type-C mode-switch in DP bridge endpoints

[Pin-yen Lin]

This series introduces bindings for anx7625/it6505 to register Type-C
mode-switch in their output endpoints, and use data-lanes property to
describe the pin connections.

The first two patch modifies fwnode_graph_devcon_matches and
cros_typec_init_ports to enable the registration of the switches.

Patch 4~6 introduce the bindings for anx7625 and the corresponding driver
modifications.

Patch 7~9 add similar bindings and driver changes for it6505.

Changes in v10:
- Collected Reviewed-by and Tested-by tags
- Replaced "void *" with "typec_mux_set_fn_t" for mux_set callbacks
- Print out the node name when errors on parsing DT
- Use dev_dbg instead of dev_warn when no Type-C switch nodes available
- Made the return path of drm_dp_register_mode_switch clearer
- Added a TODO for implementing orientation switch for anx7625
- Updated the commit message for the absence of orientation switch
- Fixed typo in the commit message

Changes in v9:
- Collected Reviewed-by tag
- Fixed subject prefix again
- Changed the naming of the example node for it6505

Changes in v8:
- Fixed the build issue when CONFIG_TYPEC=m
- Fixed some style issues
- Fixed the subject prefixes for the bindings patch
- Fixed the bindings for data-lanes properties

Changes in v7:
- Fix the long comment lines
- Extracted the common codes to a helper function
- Fixed style issues in anx7625 driver
- Removed DT property validation in anx7625 driver.
- Fixed style issues in it6505 driver
- Removed the redundant sleep in it6505 driver
- Removed DT property validation in it6505 driver
- Rebased to drm-misc-next
- Fixed indentations in bindings patches
- Added a new patch to fix indentations in Kconfig

Changes in v6:
- Changed it6505_typec_mux_set callback function to accommodate with
  the latest drm-misc patches
- Changed the driver implementation to accommodate with the new binding
- Dropped typec-switch binding and use endpoints and data-lanes properties
  to describe the pin connections
- Added new patches (patch 1,2,4) to fix probing issues
- Changed the bindings of it6505/anx7625 and modified the drivers
  accordingly
- Merged it6505/anx7625 driver changes into a single patch
