[U-Boot] [PATCH 0/6] tegra2: Add more clock/pinmux functionality

[Simon Glass]

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.
