Subject: [PATCHv2 0/2] coresight: Do not default to CPU0 for missing CPU phandle
In case of missing CPU phandle, the affinity is set default to
CPU0 which is not a correct assumption. Fix this in coresight
platform to set affinity to invalid and abort the probe in drivers.
Also update the dt-bindings accordingly.
Patch 2 allows the probe of coresight etm and cpu-debug to abort
earlier in case cpus are not available.
v2:
* Addressed review comments from Suzuki and Mathieu.
* Allows the probe of etm and cpu-debug to abort earlier
in case of unavailability of respective cpus.

coresight: Do not default to CPU0 for missing CPU phandle
coresight: Abort probe if cpus are not available
