Setting the AM335X initial clock speed in Linux

Nick Butts

Has anyone found out how to set the initial clock speed of an AM335X part in Linux? The package we plan to use only supports 500 MHz instead of the 720 MHz turbo mode. The BeagleBone does this when it starts up on USB power, but the AM335X EVM always starts at 720 MHz. I can write a script to back the speed off to 500 MHz after the kernel starts up, but I would prefer to get the kernel to automatically default to 500 MHz.

Thanks.
