The interrupt status registers of TPS65910/1 should be cleared when the associated interrupt event occurs. This work is done in the regmap irq thread - using 'ack_base' register. The ACK registers should be fixed as status register, not mask registers.
This patch fixes the infinite interrupt event problem by clearing interrupt status registers. Tested on the AM3517 Craneboard.
