The Renesas KingFisher board includes a U-Blox Neo-M8 chip with its
reset pin wired to a GPIO. To support that, we need "reset-gpio" support
(patches 2+3). But first, simplify regulator handling with a new helper
(patch 1).
Changes since v4:
* don't touch reset during open/close. Only deassert it during probe.
[patch 3]
Wolfram Sang (3):
gnss: ubx: use new helper to remove open coded regulator handling
dt-bindings: gnss: u-blox: add "reset-gpios" binding
gnss: ubx: add support for the reset gpio

The Renesas KingFisher board includes a U-Blox Neo-M8 chip. This chip
has a reset pin which is also wired on the board. Introduce a binding to
support this reset pin.

Johan, all good now?
Happy hacking,

If there are no further comments, can we have this series in 6.8.?

All good. Now applied for 6.8.
