Subject: [PATCH v2 0/2] PINT irqchip driver for NXP LPC18xx family

The LPC1850 has no less than 3 GPIO interrupt blocks. One of these
blocks is called 'gpio pin interrupt' or just PINT. LPC1850 PINT can
handle up to 8 interrupts and these have a one-to-one relationship with
the main interrupt controller (NVIC).

The interrupts on PINT can be either level or edge trigger and supports
any polarity. This patch set adds a irqchip driver for PINT on LPC18xx.

This version address the comments from Thomas and Rob.

Changes since v1:
 - use irq_gc_ack_set_bit for edge ack
 - switch to generic functions on level mask/unmask
 - use revmap to look up hwirq in handler
 - describe the interrupts property better in dt doc
