2009-05-26davinci: Encapsulate SoC-specific data in a structureMark A. Greer
Create a structure to encapsulate SoC-specific information. This will assist in generalizing code so it can be used by different SoCs that have similar hardware but with minor differences such as having a different base address. The idea is that the code for each SoC fills out a structure with the correct information. The board-specific code then calls the SoC init routine which in turn will call a common init routine that makes a copy of the structure, maps in I/O regions, etc. After initialization, code can get a pointer to the structure by calling davinci_get_soc_info(). Eventually, the common init routine will make a copy of all of the data pointed to by the structure so the original data can be made __init_data. That way the data for SoC's that aren't being used won't consume memory for the entire life of the kernel. The structure will be extended in subsequent patches but initially, it holds the map_desc structure for any I/O regions the SoC/board wants statically mapped. Signed-off-by: Mark A.

2009-04-23davinci: add arch_ioremap() which uses existing static mappingsKevin Hilman
Add arch-specific ioremap() which uses any existing static mappings in place of doing a new mapping. From now on, drivers should always use ioremap() instead of IO_ADDRESS(). In addition, remove the davinci_[read|write]* macros in favor of using ioremap. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2009-04-23davinci: major rework of clock, PLL, PSC infrastructureKevin Hilman
This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

2007-05-11[ARM] 4303/3: base kernel support for TI DaVinciKevin Hilman
Add base kernel support for the TI DaVinci platform. This patch only includes interrupts, timers, CPU identification, serial support and basic power and sleep controller init. More drivers to come.
