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

lna-supply:
description: A separate regulator supplying power for the Low Noise
Amplifier (LNA). This is an amplifier connected between the GNSS
device and the receiver antenna.
enable-gpios:
description: A GPIO line that will enable the GNSS receiver when
asserted. If this line is active low, the GPIO phandle should
consequently be tagged with the GPIO_ACTIVE_LOW flag so the operating
system can rely on asserting the line to enable the GNSS device.

GPIO line, this is used.

online, current active speed.

title: SiRFstar GNSS Receiver
maintainers:
- Johan Hovold <johan@kernel.org>
description:
The SiRFstar GNSS receivers have incarnated over the years in different
chips, starting from the SiRFstarIII which was a chip that was introduced in
2004 and used in a lot of dedicated GPS devices. In 2009 SiRF was acquired
by CSR (Cambridge Silicon Radio) and in 2012 the CSR GPS business was
acquired by Samsung, while some products remained with CSR. In 2014 CSR
was acquired by Qualcomm who still sell some of the SiRF products.
SiRF chips can be used over UART, I2C or SPI buses.
