PATCH 1/1 drivers: psci: Allow PSCI node to be disabled
From: Thierry Reding <[email protected]>
Allow disabling PSCI support (mostly for testing purposes) by setting the status property to "disabled". This makes the node behave in much the same way as proper device nodes.

This looks sensible to me; FWIW:
Lorenzo, do we need to batch this up with other PSCI patches, or should this go direct to arm-soc?
Thanks,
Mark.

I am aiming at getting the PSCI checker merged too so that we can send both patches (and others that may turn up) in one go to arm-soc, I will handle it.
Thanks !
