Our customer wants to lower power consumption as much as possible.
When i.MX28 is run mode, they would like to change an internal clock from PLL to a 24-MHz clock mode.
supposing there is a sample source code? (PLL => 24MHz mode)
And could you teach how to return it? (24MHz mode => PLL)
[Answer] Please refer to DVFS driver: DvfcUpdateSetpoint function.
function OEMPowerOff() can also give reference.
But it is important to realize 24MHz may not meet the requirement of DDR/MDDR. And CPU performance can not even fulfill audio display under the frequency.
