[PATCH V3 2/5] firmware: tegra: switch to global mrq_is_supported()

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

 



Patch "firmware: tegra: add helper to check for supported MRQs" added
an API to check if MRQ is supported. Remove the implementation from
bpmp debugfs code in favor of that.
