Subject: [PATCH v2 2/4] gpio/aspeed: Setup irqchip dynamically
Date: Thu, 5 Sep 2019 11:17:01 +1000 [thread overview]
Message-ID: <20190905011701.15981-1-rashmica.g@gmail.com> (raw)
This is in preparation for adding ast2600 support. The ast2600 requires two
GPIO drivers which each need their own irqchip.
