2009-06-19OMAP3 SDRC: set FIXEDDELAY when disabling SDRC DLLPaul Walmsley
Correspondence with the TI OMAP hardware team indicates that SDRC_DLLA_CTRL.FIXEDDELAY should be initialized to 0x0f. This number was apparently derived from process validation. This is only used when the SDRC DLL is unlocked (e.g., SDRC clock frequency less than 83MHz). Signed-off-by: Paul Walmsley <paul@pwsan.com>

2009-06-19OMAP3 clock/SDRC: program SDRC_MR register during SDRC clock changePaul Walmsley
Program the SDRC_MR_0 register as well during SDRC clock changes. This register allows selection of the memory CAS latency. Some SDRAM chips, such as the Qimonda HYB18M512160AF6, have a lower CAS latency at lower clock rates. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2009-06-19OMAP3 clock: add a short delay when lowering CORE clk ratePaul Walmsley
When changing the SDRAM clock from 166MHz to 83MHz via the CORE DPLL M2 divider, add a short delay before returning to SDRAM to allow the SDRC time to stabilize. Without this delay, the system is prone to random panics upon re-entering SDRAM. This time delay varies based on MPU frequency. At 500MHz MPU frequency at room temperature, 64 loops seems to work okay; so add another 32 loops for environmental and process variation. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2009-06-19OMAP3 clock: initialize SDRC timings at kernel startPaul Walmsley
On the OMAP3, initialize SDRC timings when the kernel boots. This ensures that the kernel is running with known, optimized SDRC timings, rather than whatever was configured by the bootloader. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2009-06-19OMAP3 clock: remove wait for DPLL3 M2 clock to stabilizePaul Walmsley
The original CDP kernel that this code comes from waited for 0x800 loops after switching the CORE DPLL M2 divider. This does not appear to be necessary. Signed-off-by: Paul Walmsley <paul@pwsan.com>

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.

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.

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.

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.
