[PATCH 0/7] Support TPS65217 PMIC interrupt in DT

[PATCH 0/7] Support TPS65217 PMIC interrupt in DT

[Milo Kim]

TPS65217 interrupt events include push button pressed/released, USB and AC 
voltage status change. AM335x bone based boards (like BB, BBB, BBG) have 
common PMIC interrupt pin (named NMI) of AM335x core.

This patchset support interrupts in device tree file.

[PATCH 1/7] ARM: dts: tps65217: Specify the interrupt controller

[Milo Kim]

TPS65217 MFD driver supports the IRQ domain to handle the charger input
interrupts and push button status event. The interrupt controller enables
corresponding IRQ handling in the charger[*] and power button driver[**].

[PATCH 7/7] mfd: tps65217: Fix mismatched interrupt number

[Milo Kim]

Enum value of 'tps65217_irq_type' is not matched with DT parsed hwirq
number[*].

The MFD driver gets the IRQ data by referencing hwirq, but the value is
different. So, irq_to_tps65217_irq() returns mismatched IRQ data.
Eventually, the power button driver enables not PB but USB interrupt
when it is probed.

According to the TPS65217 register map[**], USB interrupt is the LSB.
This patch synchronizes TPS65217 IRQ index.
