Subject: [PATCH 0/7] usb: typec: Introduce typec-switch binding
Date: Tue,  7 Jun 2022 19:00:17 +0000	[thread overview]
Message-ID: <20220607190131.1647511-1-pmalani@chromium.org> (raw)

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.

Pin-Yen Lin (1):
  drm/bridge: anx7625: Add typec_mux_set callback function

Prashant Malani (6):
  usb: typec: mux: Allow muxes to specify mode-switch
  usb: typec: mux: Add CONFIG guards for functions
  dt-bindings: usb: Add Type-C switch binding
  dt-bindings: drm/bridge: anx7625: Add mode-switch support
  drm/bridge: anx7625: Register number of Type C switches
  drm/bridge: anx7625: Register Type-C mode switches
