ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h Based on earlier discussions[1] we attempted to find a suitable location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP: DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion to dmaengine is complete. Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

ARM: OMAP2+: WDTIMER integration: fix !PM boot crash, disarm timer after hwmod reset Without runtime PM enabled, hwmod needs to leave all IP blocks in an enabled state by default so any driver access to the HW will succeed. This is accomplished by seting the postsetup_state to enabled for all hwmods during init when runtime PM is disabled. Currently, we have a special case for WDT in that its postsetup_state is always set to disabled. This is done so that the WDT is disabled and the timer is disarmed at boot in case there is no WDT driver. This also means that when runtime PM is disabled, if a WDT driver *is* built in the kernel, the kernel will crash on the first access to the WDT hardware. We can't simply leave the WDT module enabled, because the timer is armed by default after reset. That means that if there is no WDT driver initialzed or loaded before the timer expires, the kernel will reboot. To fix this, a custom reset method is added to the watchdog class of omap_hwmod. This method will *always* disarm the timer after hwmod reset. The WDT timer then will only be rearmed when/if the driver is loaded for the WDT. With the timer disarmed by default, we no longer need a special-case for the postsetup_state of WDT during init, so it is removed. Any platforms wishing to ensure the watchdog remains armed across the entire boot boot can simply disable the reset-on-init feature of the watchdog hwmod using omap_hwmod_no_setup_reset(). Tested on 3530/Overo, 4430/Panda. NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as documented in the TRM (and what happens on OMAP3.) I noticed this because testing the HWMOD_INIT_NO_RESET feature with no driver loaded, I expected a reboot part way through the boot, but did not see a reboot. Adding some debug to read the counter, I verified that right after OCP softreset, the counter is not firing. After writing the magic start sequence, the timer starts counting. This means that the timer disarm sequence added here does not seem to be needed for 4430, but is technically the correct way to ensure the timer is disarmed, so it is left in for OMAP4. Special thanks to Paul Walmsley for helping brainstorm ideas to fix this problem.
