Subject: soc: qcom: make debugfs support configurable for kryo l2 accessors
|
|
driver
|
|
|
|
Add config option to enable/disable l2 indirect access debug capability.
|
|
The driver exposes l2 indirect access debugfs interface to get/set data,
|
|
address, and target cpus so keep it disabled by default.
