Daniel Glöckner	0b3eb21b2f	xtensa: support s6000 gpio irqs and alternate function selection ... Implement an irq chip to handle interrupts via gpio. The GPIO chip initialization function now takes a bitmask denoting pins that should be configured for their alternate function. changes compared to v1: - fixed bug on edge interrupt configuration - accommodated to function name change - moved definition of VARIANT_NR_IRQS to this patch - renamed __XTENSA_S6000_IRQ_H to _XTENSA_S6000_IRQ_H as requested Signed-off-by: Daniel Glöckner <dg@emlix.com> Signed-off-by: Johannes Weiner <jw@emlix.com> Signed-off-by: Chris Zankel <chris@zankel.net>	2009-06-22 02:37:26 -07:00
Johannes Weiner	1fb137c1e3	xtensa: register gpio chip before use ... Platform initialization sets up the LED heartbeat that is controlled via GPIO. Requesting the GPIO pins fails, however, as the chip is only initialized later by a device_initcall(). Fix this up by exporting the initialization function. Let the platform set up the chip before it starts using it. Signed-off-by: Johannes Weiner <jw@emlix.com> Signed-off-by: Chris Zankel <chris@zankel.net>	2009-05-11 22:00:07 -07:00
