* OMAP3 clock: add a short delay when lowering CORE clk ratePaul Walmsley2009-06-194-18/+44
| | | | | | | | | | | | | 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>
* OMAP3 clock: initialize SDRC timings at kernel startPaul Walmsley2009-06-192-3/+36
| | | | | | | | 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>
* OMAP3 clock: remove wait for DPLL3 M2 clock to stabilizePaul Walmsley2009-06-191-3/+0
| | | | | | | | 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. 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>

| * ARM: OMAP3: mmc-twl4030 uses regulator frameworkDavid Brownell2009-05-282-168/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
