OMAP3 clock patches: first set

Hello,

These patches implement the OMAP3430 clock tree, along with the basic clock code necessary to support it. The clock definitions were drawn from 3430 ES1 and ES2 TRMs, and the patches try to adhere to the TRM as closely as is practicable.

The clock tree is mostly 3430ES1-based. A few 3430ES2 features are implemented, such as 16.8MHz SYS_CLK and PWRDN bits. Some ES2 clocks are yet to be defined, and will be added in subsequent patches. Also not included in this patch set are DPLL control patches, L3 divider code, and OPP code; these will be sent as separate patch sets.

Most of the new code is in patch 4. Patches 1 & 2 are cleanup/bugfix patches; patch 3 adds support for PWRDN bit usage in the clock framework; patches 5-7 fix the GPMC, dmtimer, and GPIO drivers for boot.

The code has been boot-tested on 3430SDP using a 3430ES1 chip. One known issue that I'm tracking - apparently there is a problem enabling the UART1 & 2 interface and functional clocks.

Thanks to Tony Lindgren and Richard Woodruff for their assistance in providing support and information. These patches also include some silicon errata drawn from the TI CDP kernel clock code, written by Karthik Dasu.

Review and comments are appreciated,

- Paul
