Subject: [PATCH 0/4] Add driver for globaltop GNSS receivers
Date: Fri, 28 Dec 2018 11:50:31 +0100 [thread overview]
Message-ID: <1545994235-8309-1-git-send-email-lollivier@baylibre.com> (raw)
Hello !
This patch series adds a new GNSS driver for the globaltop GNSS receivers.
These receivers transmits NMEA output sequence as soon as they have booted.
Power management can be done via the main supply and optional backup supply
as defined in the device tree.
The driver has been tested using a GlobalTop pa6h chipset on a Libretech-cc
board using the expansion header. Changes made in the board device tree can
be found below for reference and testing.
