[PATCH v2 08/10] ARM: tegra: harmony: Initialize regulators from DT

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

 



Device tree support for the TPS6586x PMU used on Harmony has recently
been added. This commit adds the required device tree nodes to probe the
PMU from the device tree.
