[PATCH 2/4] ARM: OMAP5: clockdomain data: add init file for omap54xx

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

 



cclock54xx_data.c now contains only init function and the clkdev mapping
that is still needed by some drivers. Eventually most of this file can
be removed, once a common location for the clk init can be found, and
the clkdev mapping is no longer needed.
