Almost the same driver for both Poulsbo and Tunnel Creek.

2011-03-18gpio/langwell: Clear edge bit before handlingThomas Gleixner1-7/+6
I don't have the specs for this beast, but it looks a lot like the PXA GPIO block. Though I bet it's the same IP and the driver should have reused the PXA code. Acknowleding the edge detect status after handling one or more gpio interrupts looks wrong. We might lose an edge which came in while we handled the previous one.

2011-03-17gpio/langwell: Fix broken irq_eoi change.Thomas Gleixner1-8/+5
commit 0766d20fd (langwell_gpio: modify EOI handling following change of kernel irq subsystem) changes - desc->chip->eoi(irq); + + if (desc->chip->irq_eoi) + desc->chip->irq_eoi(irq_get_irq_data(irq)); + else + dev_warn(pg->chip.dev, "missing EOI handler for irq %d\n", irq); With the following explanation: "Latest kernel has many changes in IRQ subsystem and its interfaces, like adding irq_eoi" for struct irq_chip, this patch will make it support both the new and old interface." This is completely bogus. #1) The changelog does not match the patch at all #2) This driver relies on the assumption that it sits behind an eoi capable interrupt line. If the implementation of the underlying chip changes from eoi to irq_eoi then this driver has to follow that change and not add a total bogosity. #3) Just mechanically changing eoi to irq_eoi without checking the background of that change is sloppy at best. Remove the sillyness and retrieve the interrupt data from irq_desc directly. No need to go through a sparse irq lookup.

2011-02-23gpio/sx150x: Do not access I2C from mask/unmask functionsThomas Gleixner1-17/+37
irq_chip->irq_mask/unmask are called with interrupts disabled and irq_desc->lock held. So we cannot access i2c from this context. That's what irq_bus_sync_unlock() is for. Store the masked information in the chip data structure and update the i2c bus from the irq_bus_sync_unlock() callback. This does not need a while(pending) loop because the update to this is always serialized via the bus lock, so we never have more than one pin update pending.

Commit a1f5f22adc3206c47e70652c12671666c65b579f ("gpio: timbgpio: irq_data conversion") was slightly too enthusiastic in converting timbgpio_irq() over to take an irq_data * argument instead of an unsigned int irq argument, as it is a flow handler, which still take IRQ numbers for now. (And on top of that, it was using the wrong accessors.) This fixes it up, and seems to build without warnings.

2011-01-13drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO ↵Andres Salomon2-1/+53
functionality This adds (well, re-adds actually) handling for events/IRQs through cs5535 GPIOs. In the wild and wooly world of CS5535, setup_event() is for assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the pair to trigger IRQs. These should really only be used in highly platform-specific drivers (such as OLPC's DCON driver). Sadly, because set_irq() uses MSRs, this causes the driver to become X86-specific.

2010-12-24cs5535-gpio: handle GPIO regs where higher (clear) bits are setAndres Salomon1-2/+6
The default for non-READ_BACK GPIO regs is to have the clear bits set; this means that our original errata fix was too simplistic. This changes it to the following behavior: - when setting GPIOs, ignore the higher order bits (they're for clearing, we don't need to care about them). - when clearing GPIOs, keep all the bits, but unset (via XOR) the lower order bit that negates the clear bit that we care about. That is, if we're clearing GPIO 26 (val = 0x04000000), we first XOR what's currently in the register with 0x0400 (GPIO 26's SET bit), and then OR that with the GPIO 26's CLEAR bit.
