Subject: [PATCH v5 0/3] extcon: usbc-tusb320: Initial TUSB320L support
Message-ID: <20210925054407.944225-1-y.oudjana@protonmail.com>

The TUSB320L is a newer chip with additional features. It is close enough t=
o TUSB320 so it works
to some extent out-of-the-box, but for some reason it can start in UFP mode=
 which is not desirable.

This series adds support for reset and mode setting for both chips, and doe=
s that while probing
to ensure the chip starts with the default mode of following the PORT pin.

Changes since v4:
 - Use ops struct instead of type enum.
Changes since v3:
 - Remove unused tusb_modes.
 - Remove extra blank line.
Changes since v2:
 - Read state before setting default mode, then update it again after reset=
ting.
 - Remove mode tracing from irq handler
 - Add a delay after reset to handle tSOFT_RESET
 - Use a separate mode setting function for each of TUSB320 and TUSB320L.
Changes since v1:
 - Split first patch into two patches, one adding support for mode setting =
and reset on TUSB320,
   and the other adding support for TUSB320L.
 - Fix dt_binding_check warning:
   ../Documentation/devicetree/bindings/extcon/extcon-usbc-tusb320.yaml:15:=
6: [warning] wrong indentation: expected 6 but found 5 (indentation)
