From: Stephen Warren <swarren@xxxxxxxxxx> The Tegra186 BPMP is also a provider of power domains. Enhance the device tree binding to describe this. Signed-off-by: Stephen Warren <swarren@xxxxxxxxxx> --- These patches all build on top of Joseph Lo's baseline BPMP binding patches[1] and enhance them to represent a few more features of the firmware.
