Subject: [PATCH] irqchip: ingenic: Get rid of the legacy IRQ domain
Date: Fri, 22 Nov 2019 18:32:33 +0100 [thread overview]
Message-ID: <20191122173233.105225-1-paul@crapouillou.net> (raw)
Get rid of the legacy IRQ domain and hardcoded IRQ base, since all the
Ingenic drivers and platform code have been updated to use devicetree.
