Subject: [RFC PATCH v2 3/3] arm64: dts: renesas: ulcb-kf: add node for GPS
From: Wolfram Sang <wsa@...nel.org>
Add the node for the GPS receiver and its VCC supply.
Signed-off-by: Wolfram Sang <wsa@...nel.org>

Changes since RFC v1:
* rebased because of patches dropped and refactored
* added static vcc-suplly
@Geert: Not sure if we need so many fixed 3v3 regulators. Most of the
other ones more or less directly derive from d_3v3. Or do you prefer it
this way?
