ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+ As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

OMAP2+: wd_timer: disable on boot via hwmod postsetup mechanism The OMAP watchdog timer IP blocks require a specific set of register writes to occur before they will be disabled[1], even if the device clocks appear to be disabled in the CM_*CLKEN registers. In the MPU watchdog case, failure to execute this reset sequence will eventually cause the watchdog to reset the OMAP unexpectedly. Previously, the code to disable this watchdog was manually called from mach-omap2/devices.c during device initialization. This causes the watchdog to be unconditionally disabled for a portion of kernel initialization. This should be controllable by the board-*.c files, since some system integrators will want full watchdog coverage of kernel initialization. Also, the watchdog disable code was not connected to the hwmod shutdown code. This means that calling omap_hwmod_shutdown() will not, in fact, disable the watchdog, and the goal of omap_hwmod_shutdown() is to be able to shutdown any on-chip OMAP device. To resolve the latter problem, populate the pre_shutdown pointer in the watchdog timer hwmod classes with a function that executes the watchdog shutdown sequence. This allows the hwmod code to fully disable the watchdog. Then, to allow some board files to support watchdog coverage throughout kernel initialization, add common code to mach-omap2/io.c to cause the MPU watchdog to be disabled on boot unless a board file specifically requests it to remain enabled. Board files can do this by changing the watchdog timer hwmod's postsetup state between the omap2_init_common_infrastructure() and omap2_init_common_devices() function calls. 1.

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.

* Errata: USBHOST Configured In Smart-Idle Can Lead To a Deadlock

* Description:
* In the following configuration :
* - USBHOST module is set to smart-idle mode
* - PRCM asserts idle_req to the USBHOST module ( This typically
* happens when the system is going to a low power mode : all ports
* have been suspended, the master part of the USBHOST module has
* entered the standby state, and SW has cut the functional clocks)
* - an USBHOST interrupt occurs before the module is able to answer
* idle_ack, typically a remote wakeup IRQ.
* Then the USB HOST module will enter a deadlock situation where it
* is no more accessible nor functional.
*
* Workaround:
* Don't use smart idle; use only force idle, hence HWMOD_SWSUP_SIDLE

*
* Description:
* When the USBHOST module is set to smart-standby mode, and when it is
* ready to enter the standby state (i.e. all ports are suspended and
* all attached devices are in suspend mode), then it can wrongly assert
* the Mstandby signal too early while there are still some residual OCP
* transactions ongoing. If this condition occurs, the internal state
* machine may go to an undefined state and the USB link may be stuck
* upon the next resume.
*
* Workaround:
* Don't use smart standby; use only force standby,
* hence HWMOD_SWSUP_MSTANDBY
