Patch series for TWL4030 power scripts and workaround for TWL errata 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, modified the
TWL4030 power script and voltage controller setuptime.
Workaround for TWL4030 errata 27 & 28 is required for
Si version less than or equal to TWL5030 ES1.1.
TWL4030 script changes rebased on Kevin's PM tree in pm branch.
Changes in v7:
changes to fix Nishanth Menon's comments
i) Added the TWL4030 Errata 27 fix
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) pmic_info struct cleanup
ii) changing sys_off signal polarity
Updated the change logs
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.
