introduce-om-gta03-features.patch
This patch adds a single file that is intended to do the job of
the several neo1973_pm_* drivers used in GTA02. It exposes the
/sys nodes
/sys/bus/platform/devices/om-gta03.0/gps_power
/sys/bus/platform/devices/om-gta03.0/gsm_power
/sys/bus/platform/devices/om-gta03.0/usbhost_power
/sys/bus/platform/devices/om-gta03.0/wlan_bt_power
at the moment which allow power control of these subsystems.
