2011-03-08msm: iommu: Remove dependency on IDRStepan Moskovchenko
Remove the depencency on the IOMMU IDR register, as it may not be accessible depending on the security configuraton. This involves moving the NCB field of IDR into the platform data. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>

2011-03-08msm: iommu: Rework clock logic and add IOMMU bus clock controlStepan Moskovchenko
Clean up the clock control code in the probe calls, and add support for controlling the clock for the IOMMU bus interconnect. With the (proper) clock driver in place, the clock control logic in the probe function can be made much cleaner since it does not have to deal with the placeholder driver anymore.

2011-03-08msm: iommu: Clock control for the IOMMU driverStepan Moskovchenko
Add clock control to the IOMMU driver. The IOMMU bus clock (and potentially an AXI clock) need to be on to gain access to IOMMU registers. Actively control these clocks when needed instead of leaving them on. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>

After commit 81b34fbecbfbf24ed95c2d80d5cb14149652408f ("OMAP2 clock: split OMAP2420, OMAP2430 clock data into their own files"), it's possible to remove dsp_irate_ick from the OMAP2420 and OMAP2430 clock files. It was originally only needed due to a 2420/2430 clock tree difference, and now that the data is in separate files, it's superfluous. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2011-03-07OMAP2+: clock: remove the DPLL rate tolerance codePaul Walmsley
Remove the DPLL rate tolerance code that is called during rate rounding. As far as I know, this code is never used, since it's been more important for callers of the DPLL round_rate()/set_rate() functions to obtain an exact rate than it is to save a relatively small amount of power.

2011-03-07OMAP2xxx: clock: fix interface clocks and clockdomains for modules in the ↵Paul Walmsley
WKUP domain The parent of the interface clocks for GPTIMER1, MPU_WDT, SYNCTIMER_32K, SCM, WDT1, and the ICR (2430 only) were all listed as being l4_ck. This isn't accurate; these modules exist inside the WKUP domain, and the interface clock to these modules runs at the SYS_CLK rate rather than the CORE L4 rate. So, create a new clock "wu_l4_ick", similar to the OMAP3 "wkup_l4_ick", that serves as the parent for these clocks. Also, these clocks were listed as existing inside core_l4_clkdm; wkup_clkdm is probably more accurate. Signed-off-by: Paul Walmsley <paul@pwsan.com>

Leaving this header file in plat-omap causes problems due to cross-dependencies with other header files that should live in mach-omap2/.

These CM_AUTOIDLE bits are now set by the clock code via the common PM code in mach-omap2/pm.c. N.B.: The pm24xx.c code that this patch removes didn't ensure that the CM_AUTOIDLE bits were set for several 2430-only modules, such as GPIO5, MDM_INTC, MMCHS1/2, the modem oscillator clock, and USBHS. Similarly, the pm34xx.c code that this patch removes didn't ensure that the CM_AUTOIDLE bits were set for USIM and the AM3517 UART4. Those cases should now be handled.

2011-03-07OMAP2+: powerdomain: add pwrdm_can_ever_lose_context()Paul Walmsley
Some drivers wish to know whether the device that they control can ever lose context, for example, when the device's enclosing powerdomain loses power. They can use this information to determine whether it is necessary to save and restore device context, or whether it can be skipped. Implement the powerdomain portion of this by adding the function pwrdm_can_ever_lose_context(). This is not for use directly from driver code, but instead is intended to be called from driver-subarch integration code (i.e., arch/arm/*omap* code). Currently, the result from this function should be passed into the driver code via struct platform_data, but at some point this should be part of some common or OMAP-specific device code.
