Isn't that true? "mpurate" is argument passed to kernel. u-boot is not doing much with it. > > > > The voltage does stabilize when smartrelex reflex is initialized. > Why do you have dependency on SR for voltage stabilization? > You can set the right voltage even w/o SR (via VP). SR is > only for optimizing Voltage for a given OPP. In the default flow, clock_arch_init() where mpurate is acted upon, I didn't want to start changing the VP. Else some part of the code in SR - related to VP - will be duplicated. OR needs to be exported. Still not made my mind; as I have been away from this problem for a while now :( ~sanjeev > > Regards > Vishwa > > > > I was trying to move smartreflex above in the init sequence; after > > i2c has been initialized. > > > > Comments/ thoughts? > > > > Best regards, > > Sanjeev > > [snip]--[snip] -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
