2009-05-28ARM: OMAP4: Add support for 4430 SDPSantosh Shilimkar
This patch updates the Makefile and Kconfig entries for OMAP4. The OMAP4430 SDP board file supports only minimal set of drivers. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-05-28ARM: OMAP4: Clock stubs since CLKDEV not in yet.Santosh Shilimkar
This patch update the common clock.c file for OMAP4. The clk_get() and clk_put() functions are moved to common place in arch/arm/common/clkdev.c Since on current OMAP4 platform clk management is still not supported, the platform file is stubbed with those functions. Once the framework is ready, this WILL be replaced with a full clkdev implementation. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-05-28ARM: OMAP4: Add minimal support for omap4Santosh Shilimkar
This patch adds the support for OMAP4. The platform and machine specific headers and sources updated for OMAP4430 SDP platform. OMAP4430 is Texas Instrument's SOC based on ARM Cortex-A9 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency.

2009-05-28ARM: OMAP3: mmc-twl4030 uses regulator frameworkDavid Brownell
Decouple the HSMMC glue from the twl4030 as the only regulator provider, using the regulator framework instead. This makes the glue's "mmc-twl4030" name become a complete misnomer ... this code could probably all migrate into the HSMMC driver now. Tested on 3430SDP (SD and low-voltage MMC) and Beagle (SD), plus some other boards (including Overo) after they were converted to set up MMC regulators properly. Eventually all boards should just associate a regulator with each MMC controller they use. In some cases (Overo MMC2 and Pandora MMC3, at least) that would be a fixed-voltage regulator with no real software control. As a temporary hack (pending regulator-next updates to make the "fixed.c" regulator become usable) there's a new ocr_mask field for those boards.

2009-05-28ARM: OMAP2/3: Add generic onenand support when connected to GPMCJuha Yrjola
Add generic onenand support when connected to GPMC and make the boards to use it. The patch has been modified to make it more generic to support all the boards with GPMC. The patch also remove unused prototype for omap2_onenand_rephase(void). Note that board-apollon.c is currently using the MTD_ONENAND_GENERIC and setting the GPMC timings in the bootloader. Setting the GPMC timings in the bootloader will not allow supporting frequency scaling for the onenand source clock. Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-05-28ARM: OMAP2/3: sDMA: Correct omap_request_dma_chain(), v2Santosh Shilimkar

2009-05-28OMAP: UART: Add sysfs interface for adjusting UART sleep timeoutJouni Hogander
This patch makes it possible to change uart sleep timeout. New sysfs entry is added (/sys/devices/platform/serial8250.<uart>/sleep_timeout) Writing zero will disable the timeout feature and prevent UART clocks from being disabled. Also default timeout is increased to 5 second to make serial console more usable. Original patch was written by Tero Kristo.

2009-05-28OMAP3: PM: UART: disable clocks when idle and off-mode supportKevin Hilman
This patch allows the UART clocks to be disabled when the OMAP UARTs are inactive, thus permitting the chip to hit retention in idle. After the expiration of an activity timer, each UART is allowed to disable its clocks so the system can enter retention. The activity timer is (re)activated on any UART interrupt, UART wake event or any IO pad wakeup. The actual disable of the UART clocks is done in the 'prepare_idle' hook called from the OMAP idle loop. While the activity timer is active, the smart-idle mode of the UART is also disabled. This is due to a "feature" of the UART module that after a UART wakeup, the smart-idle mode may be entered before the UART has communicated the interrupt, or upon TX, an idle mode may be entered before the TX FIFOs are emptied. Upon suspend, the 'prepare_suspend' hook cancels any pending activity timers and allows the clocks to be disabled immediately. In addition, upon disabling clocks the UART state is saved in case of an off-mode transition while clocks are off. Special thanks to Tero Kristo for the initial ideas and first versions of UART idle support, and to Jouni Hogander for extra testing and bugfixes.

2009-05-28OMAP2/3: PM: push core PM code from linux-omapKevin Hilman
This patch is to sync the core linux-omap PM code with mainline. This code has evolved and been used for a while the linux-omap tree, but the attempt here is to finally get this into mainline. Following this will be a series of patches from the 'PM branch' of the linux-omap tree to add full PM hardware support from the linux-omap tree. Much of this PM core code was written by Jouni Hogander with significant contributions from Paul Walmsley as well as many others from Nokia, Texas Instruments and linux-omap community.
