[PATCH v3 1/1] Registering sgx device and it's platform data

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In this patch SGX powervr_device is registered with it's platform specific
data to provide information about setting constraint through
omap_pm_set_min_bus_tput.
This patch removes the requirement of EXPORT_SYMBOL for the same function.
