From mboxrd@z Thu Jan 1 00:00:00 1970 From: nm@ti.com (Nishanth Menon) Date: Thu, 14 Mar 2013 15:58:08 -0500 Subject: [PATCH 1/8] ARM: dts: OMAP34xx: move CPU OPP tables to device tree In-Reply-To: <1363294695-658-1-git-send-email-nm@ti.com> References: <1363294695-658-1-git-send-email-nm@ti.com> Message-ID: <1363294695-658-2-git-send-email-nm@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add DT OPP table for OMAP34xx family of devices. This data is decoded by OF with of_init_opp_table() helper function. This is in preparation to use generic cpu0-cpufreq driver.
