14 Broadcom GPS chips can be used over the UART or I2C bus. The UART
15 bus requires CTS/RTS support. The number of the capsule is more
16 elaborate than the compatibles BCM4751 may be printed
17 BCM4751IFBG for example.

31 The I2C Address, not required on UART buses.
35 Main voltage supply, pin name VDD_AUXIN, typically connected
36 directly to a battery such as LiIon 3.8V battery or a 2.6V supply.
40 IO voltage supply, pin name VDDIO, typically 1.8V
44 description: An optional active low reset line, should be flagged with
48 description: Enable GPIO line, connected to pins named REGPU or NSTANDBY.
49 If the line is active low such as NSTANDBY, it should be tagged
