Subject: [PATCH v6 0/7] Register Type-C mode-switch in DP bridge endpoints


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 3~5 introduce the bindings for anx7625 and the corresponding driver
modifications.

Patch 6~7 add similar bindings and driver changes for it6505.

v5: https://lore.kernel.org/linux-usb/20220622173605.1168416-1-pmalani@chromium.org/


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

Pin-yen Lin (5):
  dt-bindings: drm/bridge: anx7625: Add mode-switch support
  drm/bridge: anx7625: Check for Type-C during panel registration
  drm/bridge: anx7625: Register Type C mode switches
  dt/bindings: drm/bridge: it6505: Add mode-switch support
  drm/bridge: it6505: Register Type C mode switches

Prashant Malani (2):
  device property: Add remote endpoint to devcon matcher
  platform/chrome: cros_ec_typec: Purge blocking switch devlinks
