Update NAND partitioning for the dm6446 evm, unmasking the hidden
data at the beginning and letting the kernel be updated from Linux.
- This is boot-compatible with TI's software (U-Boot 1.20 and both
the 2.6.10 and 2.6.18 kernels), in terms of startup and loading
kernels from flash.
- In the same way, it's also boot-compatible with mainline U-Boot,
which stores U-Boot params in block 0 not block 16.
- It's not quite compatible with systems that previously used NAND
partitions to hold (filesystem) data. The compatibilities are a
bit different based on which kernel was used previously
+ Users of TI/MV kernels no longer see mtd2 "params"
(mainline u-boot env is in a different place)
* Filesystem is now mtd2 ... vs mtd3
+ Users of GIT kernels now see mtd0 and mtd1 partitions
* Filesystem partition starts 640 KBytes earlier
* Filesystem is now mtd2 ... vs mtd0
* Linux now *uses* the flash-resident BBT
* Removes annoying slowdown/hiccup during boot
* Potentially ~64KB less space available with TI/MV kernels
If you *used* NAND partitions from Linux, there is no solution that's
fully compatible with all previous kernels in those respects ... ergo
this "best compromise". It'd be good to back back up the filesystem
data; or, carry your own backwards-compatibility patch for awhile.

Update the DaVinci GPIO code to work better on non-dm6446 parts,
notably the dm355:
- Only handle the number of GPIOs the chip actually has. So
for example on dm6467, GPIO-42 is the last GPIO, and trying
to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446.
- Enable GPIO interrupts on each 16-bit GPIO-irq bank ...
previously, only the first five were enabled, so GPIO-80
and above (on dm355) wouldn't trigger IRQs.
- Use the right IRQ for each GPIO bank. The wrong values were
used for dm355 chips, so GPIO IRQs got routed incorrectly.
- Handle up to four pairs of 16-bit GPIO banks ... previously
only three were handled, so accessing GPIO-96 and up (e.g. on
dm355) would oops.
- Update several comments that were dm6446-specific.
Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs
on the DM355 EVM.
One thing this doesn't do is handle the way some of the GPIO
numbers on dm6467 are reserved but aren't valid as GPIOs. Some
bitmap logic could fix that if needed.

Some U-Boot versions incorrectly set the number of chipselects to two
for Sequoia/Rainier boards while they only have one chipselect hardwired.
This patch adds a workaround for this, hardcoding the number of chipselects
to one for sequioa/rainer board models and reading the actual value from
the memory controller register DDR0_10 otherwise.
It also fixes another error in the way ibm4xx_denali_fixup_memsize
calculates memory size. When testing the DDR_REDUC bit, the polarity is
backwards. A "1" implies 32-bit wide memory while a "0" implies 64-bit

Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files
to use in .init_irq functions to configure the system tick GPTIMER.
Practical choices at this point are GPTIMER1 or GPTIMER12. Both of
these timers are in the WKUP powerdomain, and so are unaffected by
chip power management. GPTIMER1 can use sys_clk as a source, for
applications where a high-resolution timer is more important than
power management. GPTIMER12 has the special property that it has the
secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator. But on HS devices, it
may not be available for Linux use.
It appears that most boards are fine with GPTIMER1, but BeagleBoard
should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs
in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12.
This patch originally used a Kbuild config option to select the GPTIMER,
but was changed to allow this to be specified in board-*.c files, per
Tony's request.

The GPIO IRQ enable/disable path attempts to also enable IRQ wake
support for the parent GPIO bank IRQ as well. However, since there is
no 'set_wake' hook for the bank IRQs, these calls will always fail.
Also, since the enable will fail on the suspend path, the disable on
the resume path will trigger unbalanced enable/disable warnings.
This was discovered in the suspend/resume path on OMAP3/Beagle using
the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the
suspend/resume path.

In linus' git tree the functions can be found at:
vi arch/arm/mach-omap2/usb-tusb6010.c +200 - tusb6010_platform_retime()
vi arch/arm/mach-omap2/gpmc.c +94 - gpmc_get_fclk_period()
vi arch/arm/mach-omap2/usb-tusb6010.c +53 - tusb_set_async_mode()
vi arch/arm/mach-omap2/usb-tusb6010.c +111 - tusb_set_sync_mode()
is -ENODEV appropriate when sysclk_ps == 0?
This was found by code analysis, please review.
------------------------------>8-------------8<---------------------------------
gpmc_get_fclk_period() may return 0 when gpmc_l3_clk is not enabled. This is
not checked in tusb6010_platform_retime() nor in tusb_set_async_mode() it
seems. In tusb_set_sync_mode() this may result in a division by zero.

There is no anymore legacy driver for OMAP24XX Enhanced Audio Controller
in linux-omap and it was newer in mainline so cleanup these unneeded
defines and initialization code.

This should be done with GPIO calls. Patches against the
mainline tree welcome to add the necessary working functionality
back.

Fix the possible race condition in omap_free_dma(). Function omap_free_dma()
sets the dev_id = -1 and then accesses the channel afterwards to clear it.
But setting the dev_id=-1 makes the channel available for allocation again.
So it is possible someone else can grab it and results are unpredictable.
To avod this DMA channle is cleared first and then the dev_id = -1 is set.
Thanks to McNeil, Sean <sean.mcneil@ti.com> for ointing out this issue.

Add arch-specific ioremap() which uses any existing static mappings in
place of doing a new mapping. From now on, drivers should always use
ioremap() instead of IO_ADDRESS().
In addition, remove the davinci_[read|write]* macros in favor of using
ioremap.

This is a significant rework of the low-level clock, PLL and Power
Sleep Controller (PSC) implementation for the DaVinci family. The
primary goal is to have better modeling if the hardware clocks and
features with the aim of DVFS functionality.
Highlights:
- model PLLs and all PLL-derived clocks
- model parent/child relationships of PLLs and clocks
- convert to new clkdev layer
- view clock frequency and refcount via /proc/davinci_clocks
Special thanks to significant contributions and testing by David
Brownell.

This patch modifies parameter of microblaze_read() from 'void' to 'struct
clocksource *cs', which fixes compile warning for incompatible parameter type.
