[PATCH v2 0/2] irqchip/mchp-eic: add driver for Microchip EIC

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:
- s/mchp/microchip in bindings
- get rid of glitch filter settings
- 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
- use builtin_platform_driver instead of module_platform_driver
