The davinci pre-kernel boot code assumes that all platforms use
the same UART base address for the console.  That assumption
is not longer valid with some newer SoCs so determine the console
UART base address from the machine number passed in from u-boot.

Fix for the error when the audio module is unloaded.  On unregistering

Instead use the platform device helper function to add data.

Decouple ASP clk_*() calls from pinmmux for DM355 and DM6446.
This removes the need for dm355_psc_mux(), and is a net minor
source and runtime code shrink.

Note that this keeps the ASoC-related board setup code together,
but unfortunately that still doesn't live in mach-davinci with
all the other board setup logic.  On my DM6446 EVM this muxing
is needed; u-boot doesn't.  On the DM355 EVM, it isn't needed;
u-boot sets that up.  I have no idea if SFFSDR boards need it.

Init the SPI eeprom on the dm355 EVM.
Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

Init the DM355 SPI0 device.  Board init code would call this, which
would handle all pinmuxing needed.

This configures the second SPI interrupt for this controller; it's
not clear we'll actually want to use those controller IRQs ... but
the just-posted driver expects to have one.  (Pure PIO doesn't need
them, it can poll; and DMA can be driven by EDMA irqs.)  But it does
seem that at least on dm355 we'd want to avoid the first IRQ because
of irq mux conflicts with EDMA.

Overview
 - distinguish between PLL1- and PLL2-derived SYSCLKs
 - PLL-derived AUX ans bypass clocks are sourced
   before the multiplier and divider(s)
 - add CLK_PSC flag (set at init for clks with 'lpsc' filled out)
 - blindly dropped the remaining boot-time PSC inits
 - more lowercase clock names, and removal of '_clk' suffix in strings

and from Dave:
 - Add PSC_DSP flag for updating dm644x DSP and VICP clocks
 - When disabling unused clocks, avoid WARN() spewage
 - On dm355, list two more clocks
 - On dm64xx, list the DSP clocks too
 - Correct some LPSC definitions:  remove invalid, define dm646x ARM
 - AEMIF shouldn't be "always enabled" on dm6446 (EVM may need NOR tweaks)

Notes:
 - PWM[0,1] on dm6467 hang the system when disabled.  Add the
   'usecount = 1' workaround and 'REVISIT' comment.

TODO:
- move the device-specific PSC init into <device>.c

This was boot-tested on dm6446, dm355, dm6467 with a quick
sanity check of /proc/davinci_clocks.

* git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-async-update:
  async: use list_move_tail
  async: Rename _special -> _domain for clarity.
  async: Add some documentation.
  async: Handle kthread_run() return codes.
  async: Fix running list handling.

For historical reason, this driver used its own saving/restoring
of the PCI config space, and used the state of it on resume as
an indication as to whether it needed to re-POST the chip or not.

This methods breaks with the later core changes since the core will
have restored things for us.

This patch fixes it by removing that custom code, using standard
core methods to save/restore state, and testing for the need to
re-POST by comparing the content of a few key PLL registers.

This fixes aty128fb to properly save the PCI config space -before- it
potentially switches the PM state of the chip. This avoids a
warning with the new PM core and is the right thing to do anyway.

I also replaced the hand-coded switch to D2 with a call to the
genericc pci_set_power_state() and removed the code that switches it
back to D0 since the generic code is doing that for us nowadays.

Impact: fix spurious BUG_ON() triggered under load

module_refcount() isn't reliable outside stop_machine(), as demonstrated
by Karsten Keil <kkeil@suse.de>, networking can trigger it under load
(an inc on one cpu and dec on another while module_refcount() is tallying
 can give false results, for example).

Almost noone should be using __module_get, but that's another issue.

During early boot, ACPI RSDT/XSDT table entries are gathered into the
'initial_tables[]' array.  This array is currently statically defined (see
./drivers/acpi/tables.c).  When there are more table entries than can be
held in the 'initial_tables[]' array, the message "Truncating N table
entries!" is output.  As currently implemented, this message will always
erroneously calculate N as 0.

This patch fixes the calculation that determines how many table entries
will be missing (truncated).

Bit 11 in intel PDC definitions is meant for OS capability to handle
hardware coordination of P-states. In Linux we have always supported
hwardware coordination of P-states. Just let the BIOSes know that we
support it, by setting this bit.

Some BIOSes use this bit to choose between hardware or software coordination
and without this change below, BIOSes switch to software coordination, which
is not very optimal in terms of power consumption and extra wakeups from idle.

Some devices trigger a DEVICE_CHECK on every evalutation of _STA. This
can also be seen in commit 8b59560a
(ACPI: dock: avoid check _STA method).  If an undock is processed, the
dock driver sends a uevent and userspace might read the show_docked
property in sysfs. This causes an evaluation of _STA of the particular
device which causes the dock driver to immediately dock again.

In any case, evaluation of _STA (show_docked) does not necessarily mean
that we are docked, so check with the internal device structure.
