dt-bindings: cpufreq: Document operating-points-v2-kryo-cpu 



The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.

This change adds documentation for the DT bindings.
The "operating-points-v2-kryo-cpu" DT extends the "operating-points-v2"
with following parameters:
- nvmem-cells (NVMEM area containig the speedbin information)
- opp-supported-hw: A single 32 bit bitmap value,
  representing compatible HW:
			0:	MSM8996 V3, speedbin 0
			1:	MSM8996 V3, speedbin 1
			2:	MSM8996 V3, speedbin 2
			3:	unused
			4:	MSM8996 SG, speedbin 0
			5:	MSM8996 SG, speedbin 1
			6:	MSM8996 SG, speedbin 2
			7-31:	unused

Qualcomm Technologies, Inc. KRYO CPUFreq and OPP bindings

===================================



In Certain Qualcomm Technologies, Inc. SoCs like apq8096 and msm8996

that have KRYO processors, the CPU ferequencies subset and voltage value

of each OPP varies based on the silicon variant in use.

Qualcomm Technologies, Inc. Process Voltage Scaling Tables

defines the voltage and frequency value based on the msm-id in SMEM

and speedbin blown in the efuse combination.

The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC

to provide the OPP framework with required information (existing HW bitmap).

This is used to determine the voltage and frequency value for each OPP of

operating-points-v2 table when it is parsed by the OPP framework.



Required properties:

--------------------

In 'cpus' nodes:

- operating-points-v2: Phandle to the operating-points-v2 table to use.



In 'operating-points-v2' table:

- compatible: Should be

	- 'operating-points-v2-kryo-cpu' for apq8096 and msm8996.

- nvmem-cells: A phandle pointing to a nvmem-cells node representing the

		efuse registers that has information about the

		speedbin that is used to select the right frequency/voltage

		value pair.

		Please refer the for nvmem-cells

		bindings Documentation/devicetree/bindings/nvmem/nvmem.txt

		and also examples below.



In every OPP node:

- opp-supported-hw: A single 32 bit bitmap value, representing compatible HW.

		    Bitmap:

			0:	MSM8996 V3, speedbin 0

			1:	MSM8996 V3, speedbin 1

			2:	MSM8996 V3, speedbin 2

			3:	unused

			4:	MSM8996 SG, speedbin 0

			5:	MSM8996 SG, speedbin 1

			6:	MSM8996 SG, speedbin 2

			7-31:	unused
