Hi,
This set applies on top of the pwrdm / clkdm / voltdm usecounting patch
set I sent last week (see:
http://www.spinics.net/lists/linux-omap/msg64670.html):
Following changes done compared to previous version.
- split out the basic usecounting support as its own set (see above)
- added lots of new comments to the code, including kerneldoc style
function headers
- changed pmic->vp_vddmin / vddmax to simply vddmin / vddmax, these
are now used as limits for all voltage related operations (both
vc / vp), pmic limits are checked against the values defined for
the omap chip itself to select proper voltage levels
- some other minor fixes proposed for the previous version
TBD:
- omap4 support (will work with this once retention works for omap4)
- pmic script support for omap3 (scaling to 0V level)
Tested on omap3 beagle with retention / off, suspend and dynamic idle.
Voltage rails for vdd1 (mpu) and vdd2 (core) measured and seen to scale
correctly to retention / off voltage levels.
