This series introduces a binding for Type-C data lane switches. These control the routing and operating modes of USB Type-C data lanes based on the PD messaging from the Type-C port driver regarding connected peripherals. The first 2 patches introduce the new "typec-switch" binding as well as one user of it (the ANX7625 drm bridge). Patches 3-5 add functionality to the anx7625 driver to register the mode-switches, as well as program its crosspoint switch depending on which Type-C port has a DisplayPort (DP) peripheral connected to it. Patch 6-9 add similar bindings update and Type-C switch support to the it6505 driver. v4: https://lore.kernel.org/linux-usb/20220615172129.1314056-8-pmalani@xxxxxxxxxxxx/ Changes in v5: - Rebased on usb-next, so removed Patch v4 1/7 and Patch v4 2/7 from this version (v5) since they are already in usb-next. - Added newer Reviewed-by tags. - Added new patches (6-9) in this version for a 2nd example (it6505) of a binding of the user. Patch submission suggestions: Option 1: - Bindings patches 1/9 and 2/9 can go through the USB repo (since they are already reviewed from v4 [1]). - Bindings patch 6/9 can go through the USB repo, and the remaining patches (3-5,7-9) can go through the DRM repo. <or> - Patches 3-9 can all go through the DRM repo. Option 2: - All patches (1-9) go through the USB repo. (My apologies if I've made this confusing, and I appreciate any suggestions for better submission strategy).
