[PATCHv5 1/4] sim-auth: implementation of core sim-auth atom
by James Prestwood
The sim-auth module atom can now be used for SIM application discovery
and authentication. The atom will automatically discover SIM
applications available on the SIM and register a new DBus object under
the modem, whos name is the AID string e.g.
/modem1/A0000000871004FFFFFFFF8906190000
A list of discovered AID object paths and types can be retrieved by
calling GetApplications() under the modems (new)
org.ofono.SimAuthentication interface which returns "a{oa{sv}}" where
o = path (e.g. above)
and the dictionary contains the following properties:
Type: "Umts" or "Ims"
Name: "USim" or "ISim"
The Type signifies which interfaces the AID object will have:
Umts = org.ofono.USimApplication
Ims = org.ofono.ISimApplication
These interfaces will contain the supported USIM/ISIM authentication
algorithms. Where:
org.ofono.USimApplication has:
GetProperties()
GsmAuthenticate()
UmtsAuthenticate()
org.ofono.ISimApplication has:
GetProperties()
ImsAuthenticate()

[PATCHv4 1/6] sim-auth: implementation of core sim-auth atom
by James Prestwood
The sim-auth module atom can now be used for SIM application discovery
and authentication. The atom will automatically discover SIM
applications available on the SIM and register a new DBus object under
the modem, whos name is the AID string e.g.
/modem1/A0000000871004FFFFFFFF8906190000
A list of discovered AID object paths and types can be retrieved by
calling GetApplications() under the modems (new)
org.ofono.SimAuthentication interface which returns "a{oa{sv}}" where
o = path (e.g. above)
and the dictionary contains the following properties:
Type: "Umts" or "Ims"
Name: "USim" or "ISim"
The Type signifies which interfaces the AID object will have:
Umts = org.ofono.USimApplication
Ims = org.ofono.ISimApplication
These interfaces will contain the supported USIM/ISIM authentication
algorithms. Where:
org.ofono.USimApplication has:
GetProperties()
GsmAuthenticate()
UmtsAuthenticate()
org.ofono.ISimApplication has:
GetProperties()
ImsAuthenticate()

[PATCHv3 1/7] sim-auth: prep simauth/dbus headers
by James Prestwood
Added new dbus interfaces for SimAuth module as well as
function prototype definitions to simauth header.
org.ofono.SimAuthentication:
Interface to hold the auth object to type mapping property
org.ofono.USimApplication:
Application with USim functionality (GSM/UMTS auth)
org.ofono.ISimApplication:
Application with ISim functionality (IMS auth)

[PATCHv2 01/11] simutil: Added app type to application parser
by James Prestwood

the type makes sorting much easier for modules using the
parser.

[PATCH] nokia-gpio: do not create links to gpios in /dev/cmt
by Clayton Craft
The nokia-gpio plugin should not try to create symlinks to relevant gpio
pins under /dev/cmt, since the location it is looking is no longer
correct on newer kernels and it might change again in the future. This
patch removes code from nokia-gpio that tries to create a symlink.
Users will now need to symlink the modem gpios to /dev/cmt themselves.
On the 4.13 kernel, this can be done by, for example, adding a udev rule
to:
# ln -sf /sys/bus/hsi/devices/n900-modem /dev/cmt
