-NVIDIA Tegra186 (and later) MISC register block
-
-The MISC register block found on Tegra186 and later SoCs contains registers
-that can be used to identify a given chip and various strapping options.
-
-Required properties:
-- compatible: Must be:
- - Tegra186: "nvidia,tegra186-misc"
- - Tegra194: "nvidia,tegra194-misc"
- - Tegra234: "nvidia,tegra234-misc"
-- reg: Should contain 2 entries: The first entry gives the physical address
- and length of the register region which contains revision and debug
- features. The second entry specifies the physical address and length
- of the register region indicating the strapping options.
