Subject: [PATCH 0/4] usb: typec: tipd: add patch update support for
 tps6598x

This series extends the patch update mechanism to support the tps6598x.

Currently there is only support for the tps25750 part and some
conditional clauses are used to make a special case out of it. Now that
different parts support patch updates, a more general approach is
proposed.

The update mechanism differs from the one required by tps25750 and it is
explained in the commit message as a summary of the application note in
that respect.

Note that the series makes use of the TPS_SETUP_MS introduced in
commit 6a4d4a27f986 ("usb: typec: tps6598x: add reset gpio support"),
which is currently available in usb-next / usb-testing.

A TPS65987D has been used to test this functionality with positive
results.
