[PATCH v3 3/5] gpio/aspeed: Setup irqchip dynamically

From: Rashmica Gupta <hidden>
Date: 2019-09-06 06:26:56
Also in: linux-aspeed, linux-gpio, lkml
Subsystem: gpio subsystem, the rest · Maintainers: Linus Walleij, Bartosz Golaszewski, Linus Torvalds

This is in preparation for adding ast2600 support. The ast2600 SoC
requires two instances of the GPIO driver as it has two GPIO
controllers. Each instance needs it's own irqchip.
