When changing the L3 clock frequency, the CPU is executing from internal RAM and the SDRC clock is disabled. During this time accesses made to external DDR are stalled. If the ARM subsystem attempts to access the DDR while the SDRC clock is disabled this will stall the CPU until the access to the SDRC timeouts. A timeout on the SDRC should never occur. Once a timeout occurs all the following accesses will be aborted and the DDR is no longer accessible. Although the code being executed in the internal RAM does not directly access the DDR, it was found that the branch prediction logic in the CPU may cause the CPU to prefetch code from a DDR location while the SDRC clock is disabled. This was causing an SDRC timeout which resulted in a system hang. This patch fixes this problem by ensuring the branch prediction logic is disabled while changing the L3 clock frequency. The branch prediction logic is disabled by clearing the Z-bit in the ARM CTRL register. Disabling the branch prediction logic does not have any noticable impact on the execution time of this code section. The hardware observability signals were used to monitor the sdrc idle time with and without this patch when operating at different CPU frequencies (150MHz, 500MHz and 600MHz) and the total sdrc idle time when changing frequenct was in the range of 9-11us. This was measured on an omap3430 SDP running the omapzoom p-android-omap-2.6.29 branch. Signed-off-by:

This patch has multiple fixes together. To ensure that git bisect work across commits, all changes are clubbed together 1. Move the common control base address to control core 2. Remove the manually coeded defines and use the ones from headers. 3. Fix the the status register define in id.c for OMAP4 4. Fix all the register define in hsmmc.c 5. Use the control pad accessor API for omap4 hsmmc register accesses Signed-off-by:

On omap4 control module is divided in four IP blocks. - CTRL_MODULE_CORE 0x4a002000 - CTRL_MODULE_PAD_CORE 0x4a100000 - CTRL_MODULE_WKUP 0x4a30c000 - CTRL_MODULE_PAD_WKUP 0x4a31e000 Addressing all the modules with single base address is not possible considering 16 bit offsets. The mux code manages the pad core and pad wakeup related base address inside the mux framework. For other usage only control core and control pad bases are necessary. So this patch maps only needed pad control base address which is used by device drivers and infrastructure code The main control core base is still kept same in this patch to keep git-bisect working. This will be fixed in the relevant patch in this series. Signed-off-by:

OMAP4 IP optional clocks require explicit enable in module CTRLCLK register. In order to allow that we have to create artificial clock nodes that represent this clock inputs in the IP. Notes: - Temporary use OMAP3 names for GPIO optional clocks until the GPIO hwmod convertion is done. It will enforce the usage of OMAP4 names as the reference. - Temporary use OMAP3 names for TIMER main clock (gptX_fck) until TIMER hwmod convertion is done. During that convertion, the new name will have to be used. Signed-off-by:

The OMAP4 hwmod data introduced the new naming convention for TI IPs (See patch OMAP4: hwmod: Add partial hwmod support for OMAP4430 ES1.0) The leaf clock names are using the same IP name and thus must be modified to match the clock populated in the hwmod data. - Fix some leaf clocks nodes that were using a _iclk instead of the _fclk prefix. - Fix some wrong interface clock name for master IPs connected to interconnect. Please not that due to the fact that nodes are sorted by name, the name change will introduce a quite ugly diff a little bit hard to follow. Timers clock con_id is still using the old gptX_fck name until the gptimer driver is updated to omap_device framework. Timers entries in hwmods DB are still disabled until the migration if timer to platform_driver + omap_hwmod. Signed-off-by:

This 'legacy' OMAP2420 McBSP2 muxing code is currently broken after recent conversion to new mux code. The omap_mcbsp_request calling this code is usually called after booting whereas the omap_mux_init_signal is __init marked so null pointer dereference would occur. Fix this by removing the muxing code and let the bootloader or board file to do it if necessary. Remove also omap2_mcbsp_ops as there is no use for it. Signed-off-by:

The omap4_cm_wait_module_ready function would only check for the modules to be completely functional before declaring them ready to be accessed. There might also be instances where in the module is actually in idle (under h/w control) but should still be declared accessible, as the h/w control would make it functional when needed. Hence make omap4_cm_wait_module_ready return true in case the module is fully functional *or* in idle state. Fail only if the module is fully disabled or stuck intransition. The explaination from the TRM for the idlest bits on OMAP4 is as below for quick reference Module idle state: 0x0 func: Module is fully functional, including OCP 0x1 trans: Module is performing transition: wakeup, or sleep, or sleep abortion 0x2 idle: Module is in Idle mode (only OCP part). It is functional if using separate functional clock 0x3 disabled: Module is disabled and cannot be accessed Signed-off-by: -
