Merge tag 'tegra-for-4.12-soc' of... 

Merge tag 'tegra-for-4.12-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers

soc/tegra: Core SoC changes for v4.12-rc1

This contains PMC support for Tegra186 as well as a proper driver for
the flow controller found on SoCs up to Tegra210. This also turns the
fuse driver into an explicitly non-modular driver.

* tag 'tegra-for-4.12-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux

:
  soc/tegra: Add initial flowctrl support for Tegra132/210
  soc/tegra: flowctrl: Add basic platform driver
  soc/tegra: Move Tegra flowctrl driver
  ARM: tegra: Remove unnecessary inclusion of flowctrl header
  soc: tegra: make fuse-tegra explicitly non-modular
  soc/tegra: Fix link errors with PMC disabled
  soc/tegra: Implement Tegra186 PMC support

NVIDIA Tegra Power Management Controller (PMC)



Required properties:

- compatible: Should contain one of the following:

  - "nvidia,tegra186-pmc": for Tegra186

- reg: Must contain an (offset, length) pair of the register set for each

  entry in reg-names.

- reg-names: Must include the following entries:

  - "pmc"

  - "wake"

  - "aotag"

  - "scratch"



Optional properties:

- nvidia,invert-interrupt: If present, inverts the PMU interrupt signal.



Example:



SoC DTSI:



	pmc@c3600000 {

		compatible = "nvidia,tegra186-pmc";

		reg = <0 0x0c360000 0 0x10000>,

		      <0 0x0c370000 0 0x10000>,

		      <0 0x0c380000 0 0x10000>,

		      <0 0x0c390000 0 0x10000>;

		reg-names = "pmc", "wake", "aotag", "scratch";

	};



Board DTS:



	pmc@c360000 {

		nvidia,invert-interrupt;

	};
