[PATCH v5 0/9] usb: typec: Introduce typec-switch binding

From: Prashant Malani
Date: Wed Jun 22 2022 - 13:36:26 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 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).
