Subject: [PATCH 1/5] mfd: tps65910: use regmap irq framework for interrupt support
Date: Tue, 9 Oct 2012 16:58:32 +0530 [thread overview]
Message-ID: <1349782116-9757-2-git-send-email-ldewangan@nvidia.com> (raw)
In-Reply-To: <1349782116-9757-1-git-send-email-ldewangan@nvidia.com>
Implement irq support of tps65910 with regmap irq framework
in place of implementing locally.
This reduces the code size significantly and easy to maintain.
