Subject: [PATCH v3 0/2] irqchip/mchp-eic: add driver for Microchip EIC
Date: Fri, 10 Sep 2021 09:06:54 +0300 [thread overview]
Message-ID: <20210910060656.1061234-1-claudiu.beznea@microchip.com> (raw)
Hi,
This patch adds support for Microchip External Interrupt Controller
present on SAMA7G5. The controller supports for 2 external interrupt
lines and is connected to GIC as follows:
pinX +------+ EXT_IRQ0 +------+ int 153 (for pinX) +------+
------>| |--------->| |------------------->| |
pinY | PIO | EXT_IRQ1 | EIC | int 154 (for pinY) | GIC |
------>| |--------->| |------------------->| |
+------+ +------+ +------+
where PIO is the pin controller.
Thank you,
Claudiu Beznea
Changes in v2:
- fix compilation warning on bindings

- use s/eic@/interrupt-controller@ in bindings
- removed '' around interrupts in bindings as proposed by Rob
- removed glitch filter settings
- switched to hierarchical irqchip driver
- addressed review comments
