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. v6: https://lore.kernel.org/all/20221124102056.393220-1-treapking@chromium.org/ v5: https://lore.kernel.org/linux-usb/20220622173605.1168416-1-pmalani@chromium.org/ 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: 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: 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 | 101 +++++++++++++- .../bindings/display/bridge/ite,it6505.yaml | 95 +++++++++++-- drivers/base/property.c | 15 ++ drivers/gpu/drm/bridge/Kconfig | 21 +-- drivers/gpu/drm/bridge/analogix/Kconfig | 1 + drivers/gpu/drm/bridge/analogix/anx7625.c | 101 +++++++++++++- drivers/gpu/drm/bridge/analogix/anx7625.h | 13 ++ drivers/gpu/drm/bridge/ite-it6505.c | 119 +++++++++++++++- drivers/gpu/drm/display/drm_dp_helper.c | 132 ++++++++++++++++++ drivers/platform/chrome/cros_ec_typec.c | 10 ++ include/drm/display/drm_dp_helper.h | 16 +++ 11 files changed, 595 insertions(+), 29 deletions(-)
