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. This series is not directly related to the built-in mux in anx7625, which automatically switches between the two orientations of a single Type-C connector. This series adds support of registering mode switches for two downstream devices, while we use orientation switches for two orientations of the Type-C connector. 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. v10: https://lore.kernel.org/all/20230112042104.4107253-1-treapking@xxxxxxxxxxxx/ v9: https://lore.kernel.org/all/20230109084101.265664-1-treapking@xxxxxxxxxxxx/ v8: https://lore.kernel.org/all/20230107102231.23682-1-treapking@xxxxxxxxxxxx/ v7: https://lore.kernel.org/all/20230105132457.4125372-1-treapking@xxxxxxxxxxxx/ v6: https://lore.kernel.org/all/20221124102056.393220-1-treapking@xxxxxxxxxxxx/ v5: https://lore.kernel.org/linux-usb/20220622173605.1168416-1-pmalani@xxxxxxxxxxxx/ Changes in v11: - Added missing fwnode_handle_put in drivers/base/property.c - Collected Acked-by tag - Use fwnode helpers instead of DT - Moved the helpers to a new file - Use "reg" instead of "data-lanes" to determine the port number - Updated the description of the endpoints in the bindings - Referenced video-interfaces.yaml instead for the endpoints binding - Removed duplicated definitions from inherited schema - Moved the "data-lanes" parsing logics to bridge drivers - Removed Kconfig dependencies for the bridge drivers - Updated the usage of the private bridge driver data - Added a clarification on the anx7625 built-in mux in the cover letter 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 Pin-yen Lin (7): drm/display: Add Type-C switch helpers dt-bindings: display: 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: display: bridge: it6505: Add mode-switch support drm/bridge: it6505: Fix Kconfig indentation 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 .../display/bridge/analogix,anx7625.yaml | 94 ++++++++- .../bindings/display/bridge/ite,it6505.yaml | 101 ++++++++-- drivers/base/property.c | 16 ++ drivers/gpu/drm/bridge/Kconfig | 20 +- drivers/gpu/drm/bridge/analogix/anx7625.c | 162 +++++++++++++++- drivers/gpu/drm/bridge/analogix/anx7625.h | 20 ++ drivers/gpu/drm/bridge/ite-it6505.c | 179 +++++++++++++++++- drivers/gpu/drm/display/Makefile | 1 + drivers/gpu/drm/display/drm_dp_typec_helper.c | 114 +++++++++++ drivers/platform/chrome/cros_ec_typec.c | 10 + include/drm/display/drm_dp_helper.h | 31 +++ 11 files changed, 717 insertions(+), 31 deletions(-) create mode 100644 drivers/gpu/drm/display/drm_dp_typec_helper.c -- 2.39.1.519.gcb327c4b5f-goog
