Hi All I am developing a module on Moorestown platform running MeeGo. During the development stage, I had this problem of hooking my module to a PMIC interrupt. The PMIC documents related to D9975/D9976 gives a guideline on the architecture of this PMIC I am working on. Here I need to get an interrupt from a power button. The PMIC(into which power button is connected to) is interfaced with a System Controller Unit, Langwell, which instead is interfaced with an IA32 processor. The SCU document says that the interrupt vector which is associated with this interrupt (PMIC_INT) from PMIC is at 10. In another section of the same document, it says that PMIC GPIOs are connected to the interrupt line 18. There are other PMIC interrupts in different lines, where we associate those lines for battery, ADC, Audio, Touch screen and so on.
To confuse better, there's another revision of the document for Langwell which says that a GPIO line (GPIO Line 2) is dedicated to interrupt from PMIC. It would be very helpful, if anyone could throw some light into this. In brief, I would like to get information on which interrupt line we should be requesting for an interrupt from Power Button in PMIC. A quick response would be appreciated.
