gpio.c wilfully casts physical addresses to void __iomem * and then
fixes them up at runtime using:
bank->base = IO_ADDRESS(bank->base);
where accesses prior to this fixup are via omap_read/omap_write, and
after are by __raw_read/__raw_write. This doesn't lend itself to
static checking, nor to easy understanding of the code.
And so, OMAP_MPUIO_BASE gets to be the right type - integer like since
it's a physical address, not a MMIO pointer.

OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
for use with __raw_{read|write}* for accessing registers. Therefore,
these macros should return (void __iomem *) cookies, not integer values.
Doing this improves typechecking, and means we can find those places
where, eg, DMA controllers are incorrectly given virtual addresses to
DMA to, or physical addresses are thrown through a virtual to physical
address translation.

Ordinarily, memory holes in flatmem still have a valid memmap and is safe
to use. However, an architecture (ARM) frees up the memmap backing memory
holes on the assumption it is never used. /proc/pagetypeinfo reads the
whole range of pages in a zone believing that the memmap is valid and that
pfn_valid will return false if it is not. On ARM, freeing the memmap breaks
the page->zone linkages even though pfn_valid() returns true and the kernel
can oops shortly afterwards due to accessing a bogus struct zone *.
This patch lets architectures say when FLATMEM can have holes in the
memmap. Rather than an expensive check for valid memory, /proc/pagetypeinfo
will confirm that the page linkages are still valid by checking page->zone
is still the expected zone. The lookup of page_zone is safe as there is a
limited range of memory that is accessed when calling page_zone. Even if
page_zone happens to return the correct zone, the impact is that the counters
in /proc/pagetypeinfo are slightly off but fragmentation monitoring is
unlikely to be relevant on an embedded system.

OMAP3430ES2+ introduces a new feature: optional powerdomain context
hardware save-and-restore (SAR). Currently, this feature only applies
to USBHOST and USBTLL module context when the USBHOST or CORE
powerdomains enter a low-power sleep state[1]. This feature avoids
re-enumeration of USB devices when the powerdomains return from idle,
which is potentially time-consuming.
This patch adds support for enabling and disabling hardware
save-and-restore to the powerdomain code. Three new functions are
added, pwrdm_enable_hdwr_sar(), pwrdm_disable_hdwr_sar(), and
pwrdm_can_hdwr_sar(). A new struct powerdomain "flags" field is
added, with a PWRDM_HAS_HDWR_SAR flag to indicate powerdomains with
SAR support.
Thanks to Jouni Högander <jouni.hogander@nokia.com> for reviewing an
earlier version of these patches, and Richard Woodruff <r-woodruff2@ti.com>
for clarifying the purpose of these bits.
1. For the USBHOST controller module, context loss occurs when the
USBHOST powerdomain enters off-idle. For USBTLL, context loss
occurs either if CORE enters off-idle, or if the CORE logic is
configured to turn off when CORE enters retention-idle (OSWR).

This patch against 2.6.27-rc3 does the following changes to FSG-3 setup code:
1) Enable RTC on FSG-3 (proper name is needed). This change is needed due to a recent change in i2c.
2) i variable is only used when compiling for big endian.
So move its declaration to ARMEB ifdef to silence the warning when compiling for LE.

This patch integrates the OMAP3 clock tree with the clockdomain code.
This patch:
- marks OMAP34xx clocks with their corresponding clockdomain.
- adds code to convert the clockdomain name to a clockdomain pointer in the
struct clk during clk_register().
- modifies OMAP2 clock usecounting to call into the clockdomain code
when clocks are enabled or disabled.

This patch creates an interface to the clockdomain registers in the
PRM/CM modules on OMAP2/3. This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.
The patch also adds clockdomain usecount tracking. This is intended
to be called whenever the first clock in a clockdomain is enabled, or
when the last enabled clock in a clockdomain is disabled. If the
clockdomain is in software-supervised mode, the code will force-wakeup
or force-sleep the clockdomain. If the clockdomain is in
hardware-supervised mode, the first clock enable will add sleep and
wakeup dependencies on a user-selectable set of parent domains (usually
MPU & IVA2), and the disable will remove them.
Each clockdomain will be defined in later patches as static
structures. The clockdomain structures are linked into a list at boot
by clkdm_register(), similar to the OMAP clock code.
The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().
