Uggh.. just realized... since I was testing CPUFREQ with SMPS1 never
realized it. and searched elsewhere on topic/palmas branch as well..
Looks like we should make the following changes? since the register data
is now a parameter and it so happened that palmas_reg_info was mapping
back to a valid variable and the error is easily missed - so rename the
variable as well - I can break this up as proper series of patches for
topic/palmas - let me know what you think..
