Subject: [PATCH]OMAP3:PM :T2 keypad wakeup for OMAP3
Date: Mon, 24 Aug 2009 11:58:59 +0530 [thread overview]
Message-ID: <5A47E75E594F054BAF48C5E4FC4B92AB0309E9CD4D@dbde02.ent.ti.com> (raw)
>From : Teerth Reddy <teerth@ti.com>
This patch changes for setting the padconf value for sys_nirq line which is connected to T2 INTR1.
This will fix the T2 keypad wakeup issue on OMAP3 SDP.
