Subject: Re: [PATCH v2 08/15] mfd: max77836: Add max77836 support to max14577
 driver

> Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC
> component so the extcon, charger and regulators are almost the same. The
> max77836 however has also PMIC and Fuel Gauge.
> 
> The MAX77836 uses three I2C slave addresses and has additional interrupts
> (related to PMIC and Fuel Gauge). It has also Interrupt Source register,
> just like MAX77686 and MAX77693.
> 
> The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the
> PMIC block. The PMIC block has different I2C slave address and uses own
> regmap so another regmap_irq_chip is needed.
> 
> Since we have two regmap_irq_chip, use shared interrupts on MAX77836.
> 
> This patch adds additional defines and functions to the max14577 MFD core
