2019-07-04dt-bindings: coresight: Change CPU phandle to required propertySai Prakash Ranjan
Do not assume the affinity to CPU0 if cpu phandle is omitted. Update the DT binding rules to reflect the same by changing it to a required property.

2017-06-09coresight: bindings for CPU debug moduleLeo Yan
According to ARMv8 architecture reference manual (ARM DDI 0487A.k) Chapter 'Part H: External debug', the CPU can integrate debug module and it can support self-hosted debug and external debug. Especially for supporting self-hosted debug, this means the program can access the debug module from mmio region; and usually the mmio region is integrated with coresight. So add document for binding debug component, includes binding to APB clock; and also need specify the CPU node which the debug module is dedicated to specific CPU.
