Log:
gta02-pm-gps.patch by Willie Chen
This is GPS driver for GTA02. It deals with power on/off GPS module.
The GPS data can be generated through UART1.
gta02-power_control.patch:
- arch/arm/plat-s3c24xx/neo1973_pm_gps.c (gps_pwron_set, gps_pwron_get,
gta01_pm_gps_suspend, gta01_pm_gps_resume, gta01_pm_gps_probe,
gta01_pm_gps_remove): added support for GTA02
