ARM: EXYNOS: PL330 MDMA1 fix for revision 0 of Exynos4210 SOC
Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities. This is useful for the C
decompressor implementations used for unpacking compressed kernels.
This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.
The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.
For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:
gpio_request_one()
gpio_set_debounce()
gpio_free()
It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.
Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.
While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.
Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

This patch adds hwmod entry for davinci MDIO module,
creating parent<->child relationship between CPSW and MDIO module.
This Parent-child relation is required in order to use common resources
like, clock, but still maintaining the logical separation between them.
CPGMAC SubSystem consist of various sub-modules, like, mdio, cpdma,
cpsw, etc... These sub-modules are also used in some of Davinci
family of devices, so separate and independent platform devices &
drivers for CPSW and MDIO is implemented.
In case of AM33XX, the resources are shared and common register
bit-field is provided to control module/clock enable/disable,
makes it difficult to handle common resources from both drivers.
So the solution is, create parent<->child relationship between
CPGMAC & MDIO modules.

On OMAP4 boards using the TWL6030 PMIC, the sys_drm_msecure is
connected to the MSECURE input of the TWL6030 PMIC. This signal
controls the secure-mode operation of the PMIC. If its not mux'd
correctly, some functionality of the PMIC will not be accessible since
the PMIC will be in secure mode.
For example, if the TWL RTC is in secure mode, most of its registers
are read-only, meaning (re)programming the RTC (e.g. for wakeup from
suspend) will fail.
To fix, ensure the signal is properly mux'd as output when TWL is
intialized.
This fix is required when using recent versions of u-boot (>= v2012.04.01)
since u-boot is no longer setting the default mux for this pin.

However, MUSB on omap4 broke with these changes for legacy

Fix the regression properly by adding platform data support

Pull Xen fixes from Konrad Rzeszutek Wilk:
"There are three ARM compile fixes (we forgot to export certain
functions and if the drivers are built as an module - we go belly-up).
There is also an mismatch of irq_enter() / exit_idle() calls sequence
which were fixed some time ago in other piece of codes, but failed to
appear in the Xen code.
Lastly a fix for to help in the field with troubleshooting in case we
cannot get the appropriate parameter and also fallback code when
working with very old hypervisors."
Bug-fixes:
- Fix compile issues on ARM.
- Fix hypercall fallback code for old hypervisors.
- Print out which HVM parameter failed if it fails.
- Fix idle notifier call after irq_enter.

The commit 911dec0db4
"xen/arm: Fix compile errors when drivers are compiled as modules." exports
the neccessary functions. But to guard ourselves against out-of-tree modules
and future drivers hitting this, lets export all of the relevant
hypercalls.

Pull arm fixes from Russell King:
"Not much here again.
The two most notable things here are the sched_clock() fix, which was
causing problems with the scheduling of threaded IRQs after a suspend
event, and the vfp fix, which afaik has only been seen on some older
OMAP boards. Nevertheless, both are fairly important fixes."

Resolve this kernel boot message:
omap_hwmod: mcpdm: cannot be enabled for reset (3)
The McPDM on OMAP4 can only receive its functional clock from an
off-chip source. This source is not guaranteed to be present on the
board, and when present, it is controlled by I2C. This would
introduce a board dependency to the early hwmod code which it was not
designed to handle. Also, neither the driver for this off-chip clock
provider nor the I2C code is available early in boot when the hwmod
code is attempting to enable and reset IP blocks. This effectively
makes it impossible to enable and reset this device during hwmod init.
At its core, this patch is a workaround for an OMAP hardware problem.
It should be possible to configure the OMAP to provide any IP block's
functional clock from an on-chip source. (This is true for almost
every IP block on the chip. As far as I know, McPDM is the only
exception.) If the kernel cannot reset and configure IP blocks, it
cannot guarantee a sane SoC state. Relying on an optional off-chip
clock also creates a board dependency which is beyond the scope of the
early hwmod code.
This patch works around the issue by marking the McPDM hwmod record
with the HWMOD_EXT_OPT_MAIN_CLK flag. This prevents the hwmod
code from touching the device early during boot.
