From 7b9f0773fa0bee12b9fe3128ad424f14ece731f0 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Tue, 25 Aug 2009 16:04:48 -0400 Subject: [PATCH] G1: Add initial HTC G1 modem support G1 plugin is based on generic_at, with a bunch of stuff dropped and simplified. We use AT+CFUN=1 for powering on rather than having a configurable init string. We also manually set the default state during init (the G1 appears to start in mode V0 by default). The device (/dev/smd0) is hardcoded. --- Makefile.am | 3 + plugins/g1.c | 182 +++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 185 insertions(+) create mode 100644 plugins/g1.c diff --git a/Makefile.am b/Makefile.am index 71b402b8..c5103d7d 100644 --- a/Makefile.am +++ b/Makefile.am @@ -99,6 +99,9 @@ builtin_sources += plugins/generic_at.c builtin_modules += mbm builtin_sources += plugins/mbm.c + +builtin_modules += g1 +builtin_sources += plugins/g1.c endif if MAINTAINER_MODE diff --git a/plugins/g1.c b/plugins/g1.c new file mode 100644 index 00000000..ab88e1cb --- /dev/null +++ b/plugins/g1.c @@ -0,0 +1,182 @@ +/* + * oFono - Open Source Telephony + * + * Copyright (C) 2008-2009 Intel Corporation.
