Rajendra Nayak 99e7938def ARM: OMAP3: clock: Add 3xxx data using common struct clk 
The patch is the output from a python script which converts
from the old OMAP clk format to COMMON clk format using a
JSON parser in between which was developed by Paul Walmsley.

Signed-off-by: Rajendra Nayak <rnayak@ti.com>
[paul@pwsan.com: AM3517/05: dropped bogus hsotgusb "ick" and "fck"
 clkdev aliases; added hsotgusb_fck alias; added emac_ick and emac_fck
 aliases; replace omap2_init_clksel_parent() with
 omap2_clksel_find_parent_index(); reflow macros and parent name
 lists; add clkdm_name argument to DEFINE_STRUCT_CLK_HW_OMAP macros]
