Subject: [PATCH 2/7] omap:mailbox: fix rx interrupt disable in omap4
Date: Thu, 14 Oct 2010 21:13:23 -0500	[thread overview]
Message-ID: <1287108808-32119-3-git-send-email-h-kanigeri2@ti.com> (raw)
In-Reply-To: <1287108808-32119-1-git-send-email-h-kanigeri2@ti.com>

disabling rx interrupt on omap4 is different than its pre-decessors.
The bit in OMAP4_MAILBOX_IRQENABLE_CLR should be set to disable the
interrupts instead of clearing the bit.
