The driver uses completely bogus rounding formula for calculating period from the IDECLK frequency which gives one-off period values (e.g. 11 ns with 100 MHz IDECLK) which in turn can lead to overclocked IDE transfer timings. Actually, rounding is just wrong in this case, so use a mere division for a safe result. While at it, also: - give 'ide_palm_clk' variable a more suitable name; - get rid of the useless 'ideclkp' variable; - drop the LISP stype 'p' postfix from the 'clkp' variable's name. :-) Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: mcherkashin@ru.mvista.com Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

TUNABLE
The following parameters should be tunable at compile time. Some of them
exist as sysctls too.
This is far from complete
