2023-12-15dt-bindings: gnss: u-blox: add "reset-gpios" bindingWolfram Sang1-0/+6
The Renesas KingFisher board includes a U-Blox Neo-M8 chip. This chip has a reset pin which is also wired on the board. Introduce a binding to support this reset pin.

2022-08-25dt-bindings: Remove 'Device Tree Bindings' from end of title:Andrew Lunn4-4/+4
As indicated in link: https://lore.kernel.org/all/20220822204945.GA808626-robh@kernel.org/ DT schema files should not have 'Device Tree Binding' as part of there title: line. Remove this in most .yaml files, so hopefully preventing developers copying it into new .yaml files, and being asked to remove it.

2022-05-03dt-bindings: gnss: Add Broacom BCM4751 family bindingsLinus Walleij1-0/+69
The Broadcom BCM4751 family of (A-)GPS chips have been around for some years. The latest iteration BCM4753 is for example mounted on the Huawei HiKey970.

2022-03-20dt-bindings: gnss: Add two more chipsLinus Walleij1-0/+8
The CSR GSD4t is a CSR product using the SiRFstarIV core, and the CSR CSRG05TA03-ICJE-R is a CSR product using the SiRFstarV core. These chips have a SRESETN line that can be pulled low to hard reset the chip and in some designs this is connected to a GPIO, so add this as an optional property. Update the example with a reset line so users see that it need to be tagged as active low.

2018-06-28dt-bindings: gnss: add sirfstar bindingJohan Hovold1-0/+45
Add binding for SiRFstar-based GNSS receivers. Note that while four compatible-strings are initially added representing devices which differ in which I/O interfaces they support, they otherwise essentially share the same feature set. Pin and supply names vary slightly, as do some recommended timings. Note that the wakeup gpio is not intended to be used as a wakeup source, but rather to detect the current power state of the device (active or hibernate).

Add binding for u-blox GNSS receivers. Note that the u-blox product names encodes form factor (e.g. "neo"), chipset (e.g. "8") and variant (e.g. "q"), but that only formfactor and chipset is used for the compatible strings (for now).
