Patch series for TWL4030 power scripts for OMAP3 boards and
workaround for TWL erratum 27.
Changes for implementing TWL4030 power scripts recommended by hardware team.
Introduced a new TWL4030 power script file, which can be used by different
OMAP3 board with the power companion chip TWL4030.
Updated the changes for TWL4030 errata 27 & 28, and modified
the TWL4030 power script.
Workaround for TWL4030 erratum 27 is required for Si version less than or
equal to TWL5030 ES1.1.
TWL4030 script changes re-based on Kevin's PM tree in pm branch.
This patch series have a dependency with the patch:
http://www.spinics.net/lists/linux-omap/msg50547.html
Changes in v7:
changes to fix Nishanth Menon's comments
i) Added the workaround for TWL4030 Erratum 27
split the first patch in v6
i) fix for twl4030 script load
ii) correct the warning print during script loading
Added new patch files
i) changing sys_off signal polarity
Changes in v8:
updated the change logs
moving the TWL IDCODE checking to twl-core.c
Changes in V9:
changes to fix David Derrick's comments
i) turn OFF the NRES_PWRON resource in warm reset sequence
ii) optimize the i2c writes during resource configuration
Changes in V10:
changes for Tony's comments
i) making the TWL4030 power scripts loadable module
Since the voltage layer is evolving to a new design, the voltage dependant
changes required for the TWL4030 script are not incorporated in the patch
series.
So this TWL4030 script patch series can be tested with a separate patch for
voltage layer changes.

This changes are tested on OMAP3430 & OMAP3630 SDP with off mode enabled in
suspend path.
Tested with suspend/resume script, which will test system suspend in a
loop.
Tested for more than 1000 iterations.
Also tested the reboot with WRM_RST button & reboot command.
