[PATCH 0/7] Integrate the twl4030 power code into new twl4030 mfd

[Peter 'p2' De Schrijver]

This patchset integrates the twl4030 power code into the new twl4030 mfd framework. The scripts will be moved to the board specific data.

Peter 'p2' De Schrijver (7):
  Remove existing twl4030 power script code.
  Add defines and data types for twl4030.
  Twl4030 power code updated for new twl4030 core
  Hook twl4030 power code into twl4030 core.
  3430sdp and ldp use custom twl4030 power scripts.
  Generic twl4030 power script for 3430 based boards.
  omap3 evm beagle and overo use the generic twl4030 script

[PATCH 3/7] Twl4030 power code updated for new twl4030 core

[Peter 'p2' De Schrijver]

This patch adds the twl4030 power handling. It downloads the scripts provided
by the board configuration to the twl4030 and configures the chip to call
the relevant script for each event (processor group 1 and 2 sleep,
processor group 3 sleep, wakeup or warm reset).

[PATCH 6/7] Generic twl4030 power script for 3430 based boards.

[Peter 'p2' De Schrijver]

This is a generic twl4030 power script for 3430 based boards. It handles
sleep and wakeup events. In case of a sleep event it will first put the
Reset and Control (RC) resources to sleep and then put the voltage regulators
to sleep. In case of a wakeup event, the system clock will be started first,
then the voltage regulators will be woken up and finally the RC resources will
be woken up.

I tend to agree with the comment from Felipe that moving
this file from i2c/chips to mfd should be one patch.

Again, the general rule about such stuff is that a patch
series should preserve bisectability.  Else it gets hard
to use "git bisect" to track down particularly pernicious
problem patterns, promptly puncturing perplexing puzzles.

Don't need "=y" for that, since the CORE is already boolean.

Saying "power management features" is misleading; there are lots
of PM features this doesn't cover.  Just say "power sequencing
scripts" here too ... and maybe add a sentence saying what such
a script *is* (controlling what type of action on what type of
event).
