dt-bindings: thermal: Add BCL driver bindings

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

BCL Peripheral driver for PMIC5:

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

Qualcomm Technologies, Inc's PMIC has battery current limiting peripheral,

which can monitor for high battery current and low battery voltage in the

hardware. The BCL peripheral driver interacts with the PMIC peripheral using

the SPMI driver interface. The hardware can take threshold for notifying for

high battery current or low battery voltage events. This driver works only

with PMIC version 5, where the same BCL peripheral can be found in multiple

PMIC's that are used in a device, with limited functionalities. For example,

one PMIC can have only vbat monitoring, while the other PMIC can have both

vbat and ibat monitoring. This is a common driver, that can interact

with the multiple BCL peripherals.

Required Parameters:

- compatible: must be

	'qcom,bcl-v5' for bcl peripheral in PMIC version 5.

- reg: <a b> where 'a' is the starting register address of the PMIC

	peripheral and 'b' is the size of the peripheral address space.

- interrupts: <a b c d> Where,

		'a' is the SLAVE ID of the PMIC,

		'b' is the peripheral ID,

		'c' is the interrupt number in PMIC and

		'd' is the interrupt type.

- interrupt-names: user defined names for the interrupts. These

		interrupt names will be used by the drivers to identify the

		interrupts, instead of specifying the ID's. bcl driver will

		accept these standard interrupts.

		"bcl-ibat-lvl0",

		"bcl-ibat-lvl1",

		"bcl-vbat-lvl0",

		"bcl-vbat-lvl1",

		"bcl-vbat-lvl2",

Example:

		bcl@4200 {

			compatible = "qcom,bcl-v5";

			reg = <0x4200 0x100>;

			interrupts = <0x2 0x42 0x0 IRQ_TYPE_NONE>,

					<0x2 0x42 0x1 IRQ_TYPE_NONE>;

			interrupt-names = "bcl-ibat-lvl0",

						"bcl-vbat-lvl0";

		};

PMIC state of charge driver:

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

Battery state of charge driver can monitor for change in battery charge and

notify thermal framework, when the value goes below a certain threshold.

Required Parameters:

- compatible: must be 'qcom,msm-bcl-soc' for battery state of charge driver.

Optional Parameters:

		bcl-soc {

			compatible = "qcom,msm-bcl-soc";

		};
