> 
> This adds to the basic clock functionality already available. The concept
> of a peripheral ID is introduced, and all peripheral clock access is done
> using this ID.
> 
> Functions are provided to start, query and adjust peripheral clocks,
> including automatic selection of the best available clock based on the
> requested rate (this replaces hard-coded divisors).
> 
> On the pinmux side we can now select functions for pin groups using the
> new pinmux_set_func() function.
> 
> Expanded functions are provided to adjust and query PLL clocks.
> 
> With a full compliment of clock and pinmux functions, it should no longer
> be necessary for board/driver code to directly access clock registers. This
> change removes all such accesses.
> 
> This functionality will be used for I2C, SPI, LCD, USB, keyboard, NAND and
> other drivers for Tegra2.
> 
> At then end is a patch to enable MMC on Seaboard, to make it all worthwhile.
> 
> Note: These patches include a definition of assert() which I will happily
> remove if the one sent upstream is accepted.

This works fine on my Seaboard (T20-A03). My Harmony is put away, so I didn't test on it.
