That doesn't sound right to me. Judging from a quick look, this device
appears to be based on a mediatek chipset, so I suggest reworking
(renaming) this as a Mediatek driver (gnss type would be MTK, reflecting
the vendor protocol) even if it happens to look a lot like the current
u-blox driver.

If we ever add more features, like support for some part of the vendor
protocol or maybe 1pps, things will start diverging. As you noticed you
already have the generic serial gnss implementation to handle a lot of
the common bits.

Thanks,
