Hi Axel,

The patches look OK to me, but I cannot build them.
Even on top of linux-next, I get :
drivers/regulator/max1586.c: In function 'max1586_v6_set_voltage_sel':
drivers/regulator/max1586.c:86:2: error: 'const struct regulator_desc' has no member named 'volt_table'
drivers/regulator/max1586.c: At top level:
drivers/regulator/max1586.c:105:18: error: 'regulator_list_voltage_table' undeclared here (not in a function)
drivers/regulator/max1586.c:123:3: error: unknown field 'volt_table' specified in initializer
drivers/regulator/max1586.c:123:3: warning: initialization from incompatible pointer type [enabled by default]
drivers/regulator/max1586.c:123:3: warning: (near initialization for 'max1586_reg[1].ops') [enabled by default]

I suppose you're basing your tree on top of a set of commits not available in
linux-next (maybe Mark's regulator tree ?). As I don't have that tree in mind,
it would be kind to tell me which tree you're basing your work on, so that I
could test your last patches.

Cheers.

I think all the necessary patches are already in linux-next tree.
I have no problem to build it with linux-next 20120608.

OK, my fault, build problem.
I tested this serie with the PXA VCC-core regulation, it's fine.
