Subject: [PATCH v3 0/3] usb: typec: Add typec_port_register_altmodes()
Date: Fri,  9 Apr 2021 15:40:30 +0200
Message-ID: <> (raw)

Hi All,

Here is v3 of my series to actually make it possible to use alt-modes
on tcpm managed Type-C ports.

Note this v3 series deliberately does not include devicetree bindings
documentation, as requested by Rob. ATM the fwnodes used to register
the altmodes are only used internally to pass platform info from a
drivers/platform/x86 driver to the type-c subsystem.

When a devicetree user of this functionally comes up and the dt-bindings
have been hashed out the internal use can be adjusted to match the

Changes in v3:
- Rename typec_port_register_altmodes_from_fwnode() to
- Use fwnode_for_each_child_node()

Changes in v2:
- Drop the DT bindings doc, as requested by Rob
- Drop unnecessary fwnode parameter from

Greg, assuming there are no objections to merging this, then you hereby
have my ack for also taking the platform/x86/intel_cht_int33fe change
upstream through the USB tree.
