Subject: [PATCH v2 1/6] dt-bindings: olpc,ap-sp: add clock

The clock is necessary for the device operation, hence it's required.
Its name, "sp", stands for "Security Processor". It is one of several
names that are used for the processor that serves as the keyboard
controller on an OLPC and is consistent with the node name.
