All interrupts coming from MUIC were ignored because interrupt source register was masked. The Maxim 77693 has a "interrupt source" - a separate register and interrupts which give information about PMIC block triggering the individual interrupt (charger, topsys, MUIC, flash LED). By default bootloader could initialize this register to "mask all" value. In such case (observed on Trats2 board) MUIC interrupts won't be generated regardless of their mask status. Regmap irq chip was unmasking individual MUIC interrupts but the source was masked Before introducing regmap irq chip this interrupt source was unmasked, read and acked. Reading and acking is not necessary but unmasking is. Fixes: 342d669c ("mfd: max77693: Handle IRQs using regmap") Cc: <stable@vger.kernel.org> Signed-off-by:
