Subject: [PATCH v2 0/2] PINT irqchip driver for NXP LPC18xx family
Date: Sat, 2 Apr 2016 18:35:22 +0200 [thread overview]
Message-ID: <1459614924-32670-1-git-send-email-manabian@gmail.com> (raw)
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
