* ARM: 5972/1: nomadik-gpio: convert to platform driverRabin Vincent2010-03-193-68/+90
| | | | | | | | | | | | | | | | | | | | On the U8500 platform there are four GPIO blocks, each with a 4K address space, including the peripheral identification. However, each of these blocks have a varying number of banks, each of which have 32 GPIOs and an interrupt line. The current nomadik-gpio driver implementation can handle each of these sub-banks easily with one instance each, but cannot as-is be hooked up to them because it is an AMBA driver and it expects to see a peripheral with the appropriate peripheral ids but having only one bank and only one interrupt. Solve this by converting the driver to a platform driver.

* ARM: 5971/1: nomadik-gpio: mask/ack/unmask the parent irqRabin Vincent2010-03-191-5/+11
| | | | | | | | | | | | | | | | | Since we register as a chained handler, we need to take care of acking the parent irq. Current code had the acking disabled because just acking the interrupt disables it on some interrupt controllers (like the VIC used on Nomadik). However, not acking at all is incorrect because interrupt controllers like the GIC need an EOI indication, which is done in the ack routine. Solve this by maskacking and unmasking it appropriately, similar to how handle_level_irq operates.

| * Blackfin: don't support keypad wakeup from hibernateMichael Hennerich2010-03-091-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The on-chip keypad peripheral requires different registers to be setup depending on the standby type (standby vs hibernation). However, since the power management framework doesn't differentiate between these types, the driver doesn't know which registers to program and subsequently it avoids doing so. Always enabling the keyboard wakeup source causes misbehavior when the pins are not assigned to the keypad. If they happen to drive a certain level, they'll trigger a wake up event which is not wanted. So until the aforementioned issue can be sorted out, drop support for the wakeup source completely.
