Subject: [PATCH v3 3/5] gpio/aspeed: Setup irqchip dynamically
Date: Fri, 6 Sep 2019 16:26:44 +1000 [thread overview]
Message-ID: <20190906062644.13445-1-rashmica.g@gmail.com> (raw)
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.
