Hello,

I'm having a problem with the internal DCDC-converter on a custom
board. I'm now looking for a way to disable the internal
DCDC-converter and use the internal regulators to power the CPU and
memories. If I understand it correctly the pmu is configured in
arch/arm/cpu/arm926ejs/mxs/spl_power_init.c.


How do I disable the internal DCDC-converter and use internal linear
regulator instead?
