[PATCH v2 0/4] usb: typec: tipd: add patch update support for tps6598x

[Javier Carrasco]

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.
