Subject: [PATCH v6 01/12] irqdomain: Add non-hierarchy helper irq_domain_set_info
Date: Sat, 9 May 2015 22:39:31 +0200 [thread overview]
Message-ID: <1431203982-13217-2-git-send-email-stefan@agner.ch> (raw)
In-Reply-To: <1431203982-13217-1-git-send-email-stefan@agner.ch>
This adds the helper irq_domain_set_info() in a non-domain hierarchy
variant. This allows to use the helper for generic chip since not
all chips using generic chip support domain hierarchy.
