The clk source selection is also stored into memory, so that we know what

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.

It seems that a single driver can only get a regulator once. This patch
solves it by getting all the required regulators in one place, and from
which the submodules then get the regulators they need.

omapfb: Fix 12-bit display (RGB444 color mode) handling

Support for RGB444 (12-bit) pixel format has been introduced into omapfb/lcdc
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.

i2c-omap: Don't write IE state in unidle if 0

Commit ef871432... (i2c-omap: OMAP3: PM: (re)init for every transfer
to support off-mode) introduced a change which make the dev->iestate
contents be written to the OMAP_I2C_IE_REG every time omap_i2c_unidle
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."

SYSCTL: Print binary sysctl warnings (nearly) only once

When printing legacy sysctls print the warning message
for each of them only once.  This way there is a guarantee
the syslog won't be flooded for any sane program.

The original attempt at this made the tables non const and stored
the flag inline.

Linus suggested using a separate hash table for this, this is based on a
code snippet from him.

The hash implies this is not exact and can sometimes not print a
new sysctl due to a hash collision, but in practice this should not
be a problem

I used a FNV32 hash over the binary string with a 32byte bitmap. This
gives relatively little collisions when all the predefined binary sysctls
are hashed:

size 256
bucket
length      number
0:          [25]
1:          [67]
2:          [88]
3:          [47]
4:          [22]
5:          [6]
