The current state of the different cpuidle drivers is the different PM operations are passed via the platform_data using the platform driver paradigm. This approach allowed to split the low level PM code from the arch specific and the generic cpuidle code. Unfortunately there are complaints about this approach as, in the context of the single kernel image, we have multiple drivers loaded in memory for nothing and the platform driver is not adequate for cpuidle. This patch provides a common interface via cpuidle ops for all new cpuidle driver and a definition for the device tree. It will allow with the next patches to a have a common definition with ARM64 and share the same cpuidle driver. The code is optimized to use the __init section intensively in order to reduce the memory footprint after the driver is initialized and unify the function names with ARM64.
