for future series, could you cc uclinux-dist-devel@blackfin.uclinux.org ?  =
we=20
dont do clock management on Blackfin parts atm, but it's something we would=
=20
like to start doing.  our hardware can easily benefit from this.

basically, we have:
xtal -> pll -> divider -> core clock -> divider -> core timer
		\-> divider -> system clock
					|-> spi divider -> spi clock
					|-> i2c divider -> i2c clock
					|-> uart divider -> uart clock
					...etc...
and future parts are only going to get more complicated trees.

atm we only support changing core clock on the fly since it requires=20
reprogramming one device (the core timer).  we'd like to support changing t=
he=20
other clocks on the fly, but have no framework for doing so.  this obviousl=
y=20
would address that.
