| * gpio: ab8500: Mark brokenThomas Gleixner2011-03-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | This driver is broken in several aspects. 1) old style irq_chip functions. Sigh 2) Abuse of the unlock callback. That's not supposed to be a state machine for evrything and some more. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | irq_chip.end got obsolete with the removal of __do_IRQ(). irq-mb93093.c even lacks an implementation, but nobody noticed that it's broken since commit 88d6e1 in 2006.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make use of the new features in genirq: 1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the core code that irq_eoi() is only called when the interrupt was handled. That removes the extra status check in the callback. 2) Use the preflow handler, which is called from the fasteoi core code before the device handler. That avoids another status check and the open coded handler redirection. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: sparclinux@vger.kernel.org

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The core irq_set_type() function updates the flow type when the chip callback returns 0. So setting the type is bogus. The new core code allows to update the type in irq_data and return IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for setting the IRQ_LEVEL flag. Retrieve the IRQ_LEVEL information from irq_data which avoids a redundant sparse irq lookup as well. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
