[PATCH v3 0/7] usb: typec: Introduce typec-switch binding

From: Prashant Malani
Date: Tue Jun 14 2022 - 15:37:30 EST


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 patch introduces a change to the Type-C mux class mode-switch
matching code, while the second adds a config guard to a Type-C header.
The next couple of patches introduce the new "typec-switch" binding as
well as one user of it (the ANX7625 drm bridge).

The remaining patches 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.

v2: https://lore.kernel.org/linux-usb/20220609181106.3695103-1-pmalani@xxxxxxxxxxxx/

Changes since v2:
- Addressed review comments in typec_mux.h
- Changed error print to only print when a device is actually listed in
DT.
- Moved num_typec_switches check to beginning of function.
- Picked up Reviewed-by and Tested-by tags from v2.
