[PATCH 2/8] ARM: dts: OMAP36xx: move CPU OPP tables to device tree

Nishanth Menon nm at ti.com
Thu Mar 14 16:58:09 EDT 2013


Add DT OPP table for OMAP36xx family of devices. This data is
decoded by OF with of_init_opp_table() helper function. This
overrides the default OMAP34xx CPU OPP table definition.

This is in preparation to use generic cpu0-cpufreq driver.
