I think we probably need to add a new op to the context ioctl =
to allow the
application to request a floor for a specific clock (sclk, mclk, dclk, eclk,
etc.) so that the application can override the natural dynamic selection do=

he
kernel driver can force a higher floor for whichever clocks are requested.<=
