Hi,
Tony, I can update this patch set, or send an additional patch
that adds
the efuse support. Which will you prefer?
Well I guess updating it would be better if it's just defining them
so
we have a working patch rather than patch and fix cycle.
It took a bit longer than I expected, but here's the updated
smartreflex driver that uses the E-fuse values. Thanks to Pratheesh
for
helping out with the details of the implementation.
First patch remains as it was. Some new register and regbit defs have
been added to the second patch and the last patch now implements the
E-fuse parameters.
On my beagleboard:
root@beagleboard:/sys/power# echo -n 1 > /sys/power/sr_vdd1_autocomp
OPP3 doesn't support SmartReflex
SR1: VDD autocomp not activated
root@beagleboard:/sys/power#
root@beagleboard:/sys/power# echo -n 1 > /sys/power/sr_vdd2_autocomp
OPP3 doesn't support SmartReflex
SR2: VDD autocomp not activated
root@beagleboard:/sys/power#
The board doesn't crash anymore :)
regards,
Koen
I also left in the software hard coded values under a "Smartreflex
testing support" entry in the Kconfig. For testing purposes only.
Again, tested on 3430SDP.

Here is an updated version of the SmartReflex driver.
Patches 1 and 2 are same as before, but patch 3 has some new
things:
- Changed the register accessing to use the
prm_xxx_mod_reg{_bits}()
functions.
- Created a Kconfig entry for SmartReflex in "System type->TI OMAP
Implementations" menu.
Tested on 3430SDP.
Compiles for beagleboard, but the board hangs after:
echo -n 1 > /sys/power/sr_vdd1_autocomp
echo -n 1 > /sys/power/sr_vdd2_autocomp
But that's likely to be a beagleboard specific problem.

Koen
