2b40459b7e mfd: Allow to specify max77686 interrupt through DT or platform file also
Presently driver expects irq_gpio pin in platform data and maps it to irq
itself. But we can also directly specify the interrupt in DT or platform file.

9bdf9b4ec7 mfd: Apply irq_mask_cur before handling max77686 interrupts
According to TRM, though we mask the interrupts in interrupt-mask register,
interrupt source-register still provide the status of the masked interrupts.
So we should apply irq_mask_cur to read interrupt source-register value before
handling.

dae8a969d5 mfd: Add Maxim 77686 driver
This patch is device driver for MAX77686 chip.
MAX77686 is PMIC and includes regulator and rtc on it.
This driver is core of MAX77686 chip, so provides common support for
accessing on-chip devices. It uses irq_domain to manage irq and regmap
to read/write data to its register with i2c bus.
