[PATCH V2 2/8] ARM: dts: OMAP36xx: Add CPU OPP table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add DT OPP table for OMAP36xx/37xx family of devices. This data is
decoded by OF with of_init_opp_table() helper function.

OPP data here is based on existing opp3xxx_data.c

This is in preparation to use generic cpufreq-cpu0 driver for device
tree enabled boot. Legacy non device tree enabled boot continues to
use omap-cpufreq.c and opp3xxx_data.c.
