Here's the mt3339-based one: https://linxtechnologies.com/wp/wp-content/uploads/rxm-gps-fm.pdf But hopefully we can reuse this driver for mt3337 and any other variants too. > > - ublox IT530 > > - https://www.u-blox.com/sites/default/files/products/documents/IT530_DataSheet_%28FTX-HW-12008%29.pdf > > > > All with uart-interface only and similar pins names, although the ublox > > device do have some additional features we can worry about later. > > > > As all but the ublox device use VBACKUP for the backup supply, do you > > mind if I change the binding to use "vbackup-supply" instead of > > "v-bckp-supply" (which is a ublox-ism) when applying? > > I don't mind.
