t.clk_activation = gpmc_ticks_to_ns(1);

was used so that gpmc_cs_set_timings would do gpmc_ns_to_ticks over
it & hence effectively 1 tick would get programmed in the register
for clock activation.

A value of 1 for clk_activation also should work due to rounding
effect.

But I am unable to find reason for failure upon using
gpmc_ticks_to_ns(1), which seems to me right thing to be used.
Let me try to invoke tusb6010 functions in beagle board,
observe timings so that at least I will get an idea
what is going on here (even though it is guaranteed to crash)

Afzal
