-Subject: [PATCH] Enable GPS only if it was powered on before suspending the device
-
- Similar to the neo1974_pm_gsm.c keep a static struct around. On suspend
- we will save the current power state, on resume we will use this
- information to enable power of the GPS only when it was powered on before.
- This is passing basic tests with screen /dev/ttySAC1 on suspend and resume.
-
- Only do this for the GTA02 as I don't have a gllin setup for the GTA01
-
- I wonder why the suspend and resume code is not using gps_pwron_set and why
- for the GTA02 we need to keep the state of the GPIOs, this should be done
- by the s3c code.
