Subject: Re: [PATCH 0/4] Add driver for globaltop GNSS receivers
Date: Thu, 03 Jan 2019 17:04:35 +0100 [thread overview]
Message-ID: <86bm4x6830.fsf@baylibre.com> (raw)
In-Reply-To: <1545994235-8309-1-git-send-email-lollivier@baylibre.com>
As suggested by Neil Armstrong - this GNSS device seems to behave
like
most generic GNSS receivers.
I'll send a v2 with a generic driver that works for both GlobalTop
and
u-blox.
Please ignore this serie.
Thanks,
Loys
