Cover letter [U-Boot] [PATCH v2 0/6] tegra2: Add more clock/pinmux functionality
Hi Simon,

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.Changes in v2:
- Removeassert()which is now incommon.h
Series applied to u-boot-arm/master, thanks!
Amicalement,
