OMAP: DSS2: enable VDDS_DSI when using DPI

It looks like on OMAP3 some DSS pins need VDDS_DSI to function properly.

This has not been confirmed from TI, but looking at figure 15-1 "Display
subsystem highlight" from the TRM, some data pins come near the DSI and SDI
blocks. This is not very hard evidence, but the fact remains that with the
power on, pixels are ok, and with the power off, pixels are not ok.

It may also be that VDDS_SDI is needed to power some pins, but as normally
both VDDS_SDI and VDDS_DSI come from the same power source, this hasn't
been shown.

solves it by getting all the required regulators in one place, and from
which the submodules then get the regulators they need.

by Mark Underwood on 2006-05-26 (commit
f74edb6668aad9fc8e81585861b18f996c78a574) in preparation for Amstrad Delta
(E3) videophone LCD display support.

Before the Amstrad Delta LCD patch by Jonathan McDowell was applied (on
2006-08-04, commit 8d22fb2ea004cdb6379b54c1a8fd1546cfe40ed7), omapfb and lcdc
code was changed substantially (commit
e563dc81aa01bd8bbb01bc53975a15c398715f62 dated 2006-06-26) in a way that broke
Mark's 12-bit display support. Than, a patch by Jonathan, that supposed to
correct the problem, was introduced immediatelly (on 2006-08-04, commit
e10a75b49e7a57ae17c28b705153c70eba15a8ef).

As a result, the Amstrad Delta display was working correctly at boot time,
with fbset reporting:

geometry 480 320 480 320 16
...
rgba 4/8,4/4,4/0,0/0

However, after first framebuffer reinitialization, colors were no longer being
displayed correctly and fbset was reporting:

        rgba 5/11,6/5,5/0,0/0

The patch tries to correct the issue by setting plane->color_mode depending on
panel->bpp, not var->bits_per_pixel.

acerhdf: limit modalias matching to supported

BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958
The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models.  This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T).  This is not
fatal but worries users that see this message.  Limiting the moule alias
to models starting with AOA or DOA for Packard Bell.

ACPI: do not select ACPI_DOCK from ATA_ACPI

In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix
ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because
of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m.

However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43
("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.

This makes the kernel ~5 Kb smaller for people who don't have a dock by
allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y.

i2c-omap: OMAP3: Fix I2C lockup during timeout/error cases

Current OMAP3 I2C driver code does not follow the correct sequence for soft
reset. Due to this, lock up issues are reported during timeout/error cases.

This patch fixes above issue by disabling I2C controller as per OMAP3430 TRM
for soft reset. As per TRM, I2C controller needs to be disabled as a first
step during soft reset.

Here is correct soft reset sequence:
a. Ensure that the module is disabled
(clear the I2Ci.I2C_CON[15] I2C_EN bit to 0).
b. Set the I2Ci.I2C_SYSC[1] SRST bit to 1.
c. Enable the module by setting I2Ci.I2C_CON[15] I2C_EN bit to 1.
d. Check the I2Ci.I2C_SYSS[0] RDONE bit until it is set to 1 to
indicate the software reset is complete.

Commit ef871432... (i2c-omap: OMAP3: PM: (re)init for every transfer

is called.  Previously, the state was only written if it wasn't equal
to zero.

In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(),
in which case dev->iestate has not yet been initialized and will be set
to zero.  Having this value written to the registers causes deadlock
while booting.

As such, this change restores the original functionality.

Revert "x86, ucode-amd: Ensure ucode update on suspend/resume after CPU off/online cycle"

This reverts commit 9f15226e75583547aaf542c6be4bdac1060dd425.  It's just
wrong, and broke resume for Rafael even on a non-AMD CPU.

As Rafael says:
 "... it causes microcode_init_cpu() to be called during resume even for
  CPUs for which there's no microcode to apply.  That, in turn, results
  in executing request_firmware() (on Intel CPUs at least) which doesn't
  work at this stage of resume (we have device interrupts disabled, I/O
  devices are still suspended and so on).

  If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is
  known to us" , so before commit 9f15226e755 microcode_resume_cpu() was
  called for all CPUs already in the system during suspend, which was
  the right thing to do.  The commit changed it so that the CPUs without
  microcode to apply are now treated as "unknown", which is not quite
  right.

  The problem this commit attempted to solve has to be handled
  differently."
