[PATCH v2 0/8] gnss: add new GNSS subsystem

2018-05-30 Thread Johan Hovold
This series adds a new subsystem for GNSS receivers (e.g. GPS receivers). While GNSS receivers are typically accessed using a UART interface they often also support other I/O interfaces such as I2C, SPI and USB, while yet other devices use iomem or even some form of remote-processor messaging (rpm
