Subject: [PATCH 0/2] mutiple selectable capabilities in tcpm

In commit a7cff92f0635 ("usb: typec: USB Power Delivery helpers for
ports and partners"), typec_operations has two new ops .pd_get and
.pd_set providing selection of different PD capabilities. This commit
implements these two ops in tcpm.

To support multiple capabilities, new dt-binding properties need to be
defined to create a tree structure for the driver to get each set of
capabilities one by one. The first tier of the child node under
connector is called "capabilities". Under this child node lies several
2nd tier of child nodes whose names are in the pattern of ^caps[0-9]+$.
And the source and sink capabilities are placed in these nodes.
