91a0b089f8 omap4 hsmmc: Register offset handling
In OMAP4, as per new PM programming model, the legacy registers
which were there in OMAP3 are all shifted by 0x100 while new one's
are added from offset 0 to 0x10.
For OMAP4, the register offset appending of 0x100 done in devices.c
currently, is moved to driver file.This change fits in for current
implementation as well as once the driver undergoes hwmod adaptation.

a3fed9bc18 omap3: Prevent SDRC deadlock when L3 is changing frequency
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.

0c3492467c omap4: control: Add ctrl_pad_base to omap_globals
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.

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

0e43327191 OMAP4: clock: Fix clock names and align with hwmod names
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.

OMAP USBOTG module has a requirement to set the autoidle bit only after
setting smartidle bit. Modified the _sys_enable api to set the smartidle
first and then the autoidle bit. Setting this will not have any impact on the
other modules.

ff173d4552 OMAP4: PM: Declare idle modules as functional too
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

f39f4898ac OMAP: omap_device: Fix to support multiple hwmods for a single device
Currently there is a bug in the existing omap_device core code when
extracting the hwmod structures passed to omap_device_build_ss(). This bug
gets exposed only when passing multiple hwmod structures to
omap_device_build_ss() resulting in incorrect extraction from second hwmod
structure.

This fix uses the pointer to pointer to omap_hwmod structure (array of
pointers to omap_hwmod structure) passed to omap_device_build_ss() to
correctly extract the appropriate omap_hwmod structure.

This patch has been created and tested on lo/master and mainline.

The timer hwmod adaptation will eventually fix it in a proper way.
