mfd: Add support for twl6030 irq framework
This patch adds support for phoenix interrupt framework. New iInterrupt status register A, B, C are introduced in Phoenix and are cleared on write. Due to the differences in interrupt handling with respect to TWL4030, twl6030-irq.c is created for TWL6030 PMIC Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Balaji T K <balajitk@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Reviewed-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
