2009-08-26davinci: EDMA: add support for dm646xSudhakar Rajashekhara
Enables module clock for DM646x EDMA channel controller and transfer controller. Signed-off-by: Naresh Medisetty <naresh@ti.com> Signed-off-by: Sudhakar Rajashekhara <sudhakar.raj@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2009-08-26davinci: EDMA: multiple CCs, channel mapping and API changesSudhakar Rajashekhara
- restructure to support multiple channel controllers by using additional struct resources for each CC - interface changes visible to EDMA clients Introduce macros to build IDs from controller and channel number, and to extract them. Modify the edma_alloc_slot function to take an extra argument for the controller. Also update ASoC drivers to use API. ASoC changes Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> - Move queue related mappings to dm<soc>.c EDMA in DM355 and DM644x has two transfer controllers while DM646x has four transfer controllers. Moving the queue to tc mapping and queue priority mapping to dm<soc>.c will be helpful to probe these mappings from platform device so that the machine_is_* testing will be avoided. - add channel mapping logic Channel mapping logic is introduced in dm646x EDMA. This implies that there is no fixed association for a channel number to a parameter entry number. In other words, using the DMA channel mapping registers (DCHMAPn), a PaRAM entry can be mapped to any channel. While in the case of dm644x and dm355 there is a fixed mapping between the EDMA channel and Param entry number.

2009-08-25ARM: OMAP: McBSP: Merge two functions into omap_mcbsp_start/_stopJarkko Nikula
Functionality of functions omap_mcbsp_xmit_enable and omap_mcbsp_recv_enable can be merged into omap_mcbsp_start and omap_mcbsp_stop since API of those omap_mcbsp_start and omap_mcbsp_stop was changed recently allowing to start and stop individually the transmitter and receiver. This cleans up the code in arch/arm/plat-omap/mcbsp.c and in sound/soc/omap/omap-mcbsp.c which was the only user for those removed functions.

2009-08-18iop3xx: ATU and PCI memory configuration correctedAaro Koskinen
There are two 64 MB outbound memory windows at bus addresses 0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI memory. Currently, on iop32x, only the lower window is available for allocations, limiting the available space to 64 MB. On iop33x the full 128 MB can be allocated, but the translation value is wrong for the upper window. The patch enables the full 128 MB space on iop32x and corrects the initialization of OMWTVR1. Redundant definitions are deleted. Tested using a Thecus N2100 board with a graphics adapter in the expansion slot. Both windows are in use: 00:05.0 VGA compatible controller: XGI Technology Inc.
