This series adds a driver for Tegra210 BPMP firmware. The BPMP is a
specific processor in Tegra210 chip, which runs firmware for assisting
in entering deep low power states (suspend to ram), and offloading
DRAM memory clock scaling on some platforms.

The series consist of first refactoring the existing BPMP driver by
first renaming the terminology used for communication, then splitting
out the Tegra186 chip specific parts, and finally adding the needed
functionality for Tegra210.

Timo Alho (4):
  firmware: tegra: reword messaging terminology
  firmware: tegra: refactor bpmp driver
  firmware: tegra: add bpmp driver for Tegra210
  dt-bindings: firmware: Add bindings for Tegra210 BPMP
