Subject: [PATCH v2 2/4] gpio/aspeed: Setup irqchip dynamically
Date:   Thu,  5 Sep 2019 11:17:01 +1000
Message-Id: <20190905011701.15981-1-rashmica.g@gmail.com>

Precedence: bulk

This is in preparation for adding ast2600 support. The ast2600 requires two
GPIO drivers which each need their own irqchip.
