2018-05-16gpio: dwapb: Add support for 1 interrupt per port A GPIOPhil Edworthy
The DesignWare GPIO IP can be configured for either 1 interrupt or 1 per GPIO in port A, but the driver currently only supports 1 interrupt. See the DesignWare DW_apb_gpio Databook description of the 'GPIO_INTR_IO' parameter. This change allows the driver to work with up to 32 interrupts, it will get as many interrupts as specified in the DT 'interrupts' property. It doesn't do anything clever with the different interrupts, it just calls the same handler used for single interrupt hardware. ACPI companion code provided by Hoan Tran <hotran@apm.com>. This was tested on X-Gene by Hoan.

2018-05-16mfd: tps65911-comparator: Fix an off by one bugLee Jones
The COMP1 and COMP2 elements are in 0 and 1 respectively so this code is accessing the wrong elements and one space beyond the end of the array. The "id" variable is never COMP (0) so that code can be removed.

2018-05-16mfd: axp20x: Correct AXP806 POK interrupt prefixChen-Yu Tsai
When AXP806 support was added, POK was incorrectly expanded to PWROK. However, the datasheet lists them as POK[LSNP], which is the same as on the AXP288. Furthermore, the registers associated with POK functions are the same as the PEK on the other AXP PMICs. This suggests that "POK" means "Power On Key", much like "PEK" means "Power Enable Key", instead of "Power OK". This patch changes the "PWROK" prefix to "POK" for these interrupts.

2018-05-16mfd: axp20x: Use DEFINE_RES_IRQ to declare resources for mfd_cellsChen-Yu Tsai

2018-05-16mfd: arizona: Update reset pin to use GPIODCharles Keepax
Now GPIOD has support for both pdata systems and for non-standard DT bindings the Arizona reset GPIO can be converted to use it. Worth noting gpiod_set_raw_value_cansleep is used to match the behaviour of the old GPIOs. This is because the part is fairly widely used and it is unknown how many DTs are correctly setting active low through device tree, so to avoid breaking any existing users it is best to match the previous behaviour.
