Subject: [PATCHv4 0/1] 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.
v4:
* Fix return for !CONFIG_ACPI and !CONFIG_OF.
v3:
* Addressed review comments from Suzuki and updated
acpi_coresight_get_cpu.
* Removed patch 2 which had invalid check for online
cpus.
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.
