Subject: [PATCH v3 5/9] ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs
Date: Sat, 19 Jan 2013 04:07:44 +0100 [thread overview]
Message-ID: <201301190407.44867.heiko@sntech.de> (raw)
In-Reply-To: <201301190403.50317.heiko@sntech.de>
Previously the irq init used s3c24xx_init_irq and an additional
arch_initcall to add the cpu specific irqs.
To be able to simplyfy the irq init later, create a new function
s3c416_init_irq, which then calls s3c24xx_init_irq but also adds
the cpu specific irqs.
