Silicon/SynQuacer/DeviceTree: remove SCPI/MHU nodes

[edk2] [PATCH edk2-platforms] Silicon/SynQuacer/DeviceTree: remove SCPI/MHU nodes

Posted by Ard Biesheuvel 6 years, 2 months ago

On our SynQuacer based platform, power state handling and other
low-level duties are handled by the secure firmware, not by the
OS, so remove the various MHU/SCPI related nodes from the device
tree.
