[PATCH V2 3/4] ARM: tegra: add LP1 support code for Tegra124

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

 



The LP1 suspend procedure is the same with Tegra30 and Tegra114. Just
need to update the difference of the register address, then we can
continue to share the code.
