OMAP2/3/4 PRCM: add module IDLEST wait code After a hardware module's clocks are enabled, Linux must wait for it to indicate readiness via its IDLEST bit before attempting to access the device, otherwise register accesses to the device may trigger an abort. This has traditionally been implemented in the clock framework, but this is the wrong place for it: the clock framework doesn't know which module clocks must be enabled for a module to leave idle; and if a module is not in smart-idle mode, it may never leave idle at all. This type of information is best stored in a per-hardware module data structure (coming in a following patch), rather than a per-clock data structure. The new code will use these new functions to handle waiting for modules to enable. Once hardware module data is filled in for all of the on-chip devices, the clock framework code to handle IDLEST waiting can be removed. Signed-off-by: Paul Walmsley <paul@pwsan.com>

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.

This facilitates the future conversion of the CM code to a driver, and also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed by a subsequent patch. Some modules have IDLEST registers that aren't in the CM module, such as the AM3517 IDLEST bits. So we also need a fallback function for these non-CM odd cases.

OMAP3: PRM/CM: separate CM context save/restore; remove PRM context save/restore The OMAP3 PRM module is in the WKUP powerdomain, which is always powered when the chip is powered, so it shouldn't be necessary to save and restore those PRM registers. Remove the PRM register save/restore code, which should save several microseconds during off-mode entry/exit, since PRM register accesses are relatively slow. While doing so, move the CM register save/restore code into CM-specific code. The CM module has been distinct from the PRM module since 2430. This patch includes some minor changes to pm34xx.c.

OMAP3: PM: Do not rely on ROM code to restore CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL As per OMAP3 erratum (i671), ROM code adds extra latencies while restoring CM_AUTOIDLE_PLL register, if AUTO_PERIPH_DPLL is equal to 1. This patch stores 0's in scratchpad content area corresponding to AUTO_PERIPH_DPLL, to prevent ROM code to try to lock per DPLL, since it won't respect proper programing scheme. This register is then stored in prcm context. The saving and restore is now done by kernel side. Here follow the erratum description DESCRIPTION After OFF mode transition, among many restorations, the ROM Code restores the CM_AUTOIDLE_PLL register, and after that, it tries to relock the PER DPLL. In case the restoration data stored in scratchpad memory contains a field CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL = 1, then the way the ROM Code restores and locks the PER DPLL does not respect the PER DPLL programming scheme. In that case, the DPLL might not lock. Meanwhile, when trying to lock the PER DPLL, the ROM Code does not hang. Only extra latencies are introduced at wake-up. WORKAROUND When saving the context-restore structure in scratchpad memory, in order to respect the PER DPLL programming scheme, it is advised to store 0 in the CM_AUTOIDLE_PLL.AUTO_PERIPH_DPLL field of the saved structure. After wake-up, the application should store in CM_AUTOIDLE_PLL register the right desired value.

OMAP3: PRM/CM: separate CM context save/restore; remove PRM context save/restore The OMAP3 PRM module is in the WKUP powerdomain, which is always powered when the chip is powered, so it shouldn't be necessary to save and restore those PRM registers. Remove the PRM register save/restore code, which should save several microseconds during off-mode entry/exit, since PRM register accesses are relatively slow. While doing so, move the CM register save/restore code into CM-specific code. The CM module has been distinct from the PRM module since 2430. This patch includes some minor changes to pm34xx.c.

ARM: OMAP2+: CM/clock: convert _omap2_module_wait_ready() to use SoC-independent CM functions Convert the OMAP clock code's _omap2_module_wait_ready() to use SoC-independent CM functions that are provided by the CM code, rather than using a deprecated function from mach-omap2/prcm.c. This facilitates the future conversion of the CM code to a driver, and also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed by a subsequent patch. Some modules have IDLEST registers that aren't in the CM module, such as the AM3517 IDLEST bits. So we also need a fallback function for these non-CM odd cases. Create a temporary one in mach-omap2/clock.c, intended to exist until the SCM drivers are ready. Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Vaibhav Hiremath <hvaibhav@ti.com>

ARM: OMAP3: CM/control: move CM scratchpad save to CM driver OMAP3 PM code for off-mode currently saves the scratchpad contents for CM registers within OMAP control module driver. However, as we are separating CM code into its own driver, this must be moved also. This patch adds a new API for saving the CM scratchpad contents and uses this from the high level scratchpad save function.
