Firmware on certain boards (e.g. ODROID-U3) can leave incorrect L2C prefetch
settings configured in registers leading to crashes if L2C is enabled
without overriding them. This patch introduces bindings to enable
prefetch settings to be specified from DT and necessary support in the
driver.

 is missing]
Why?  What if the boot loader has already set these up appropriately?  Why
should we force people to list these in the DT?
