		What: /sys/class/chromeos/<ec-device-name>/flashinfo
		Date: August 2015
		KernelVersion: 4.2
		Description:
		Show the EC flash information.

		What: /sys/class/chromeos/<ec-device-name>/kb_wake_angle
		Date: March 2018
		KernelVersion: 4.17
		Description:
		Control the keyboard wake lid angle. Values are between
		0 and 360. This file will also show the keyboard wake lid
		angle by querying the hardware.

		KernelVersion: 4.2
		Description:
		Tell the EC to reboot in various ways. Options are:
		"cancel": Cancel a pending reboot.
		"ro": Jump to RO without rebooting.
		"rw": Jump to RW without rebooting.
		"cold": Cold reboot.
		"disable-jump": Disable jump until next reboot.
		"hibernate": Hibernate the EC.
		"at-shutdown": Reboot after an AP shutdown.

		What: /sys/class/chromeos/<ec-device-name>/lightbar/brightness
		Date: August 2015
		KernelVersion: 4.2
		Description:
		Writing to this file adjusts the overall brightness of
		the lightbar, separate from any color intensity. The
		valid range is 0 (off) to 255 (maximum brightness).

		What: /sys/class/chromeos/<ec-device-name>/lightbar/interval_msec
		Date: August 2015
		KernelVersion: 4.2
		Description:
		The lightbar is controlled by an embedded controller (EC),
		which also manages the keyboard, battery charging, fans,
		and other system hardware. To prevent unprivileged users
		from interfering with the other EC functions, the rate at
		which the lightbar control files can be read or written is
		limited.

		Reading this file will return the number of milliseconds
		that must elapse between accessing any of the lightbar
		functions through this interface. Going faster will simply
		block until the necessary interval has lapsed. The interval
		applies uniformly to all accesses of any kind by any user.

		What: /sys/class/chromeos/<ec-device-name>/lightbar/led_rgb
		Date: August 2015
		KernelVersion: 4.2
		Description:
		This allows you to control each LED segment. If the
		lightbar is already running one of the automatic
		sequences, you probably won’t see anything change because
		your color setting will be almost immediately replaced.
		To get useful results, you should stop the lightbar
		sequence first.

		The values written to this file are sets of four integers,
		indicating LED, RED, GREEN, BLUE. The LED number is 0 to 3
		to select a single segment, or 4 to set all four segments
		to the same value at once. The RED, GREEN, and BLUE
		numbers should be in the range 0 (off) to 255 (maximum).
		You can update more than one segment at a time by writing
		more than one set of four integers.

		What: /sys/class/chromeos/<ec-device-name>/lightbar/program
		Date: August 2015
		KernelVersion: 4.2
		Description:
		This allows you to upload and run custom lightbar sequences.

		What: /sys/class/chromeos/<ec-device-name>/lightbar/sequence
		Date: August 2015
		KernelVersion: 4.2
		Description:
		The Pixel lightbar has a number of built-in sequences
		that it displays under various conditions, such as at
		power on, shut down, or while running. Reading from this
		file displays the current sequence that the lightbar is
		displaying. Writing to this file allows you to change the
		sequence.

		What: /sys/class/chromeos/<ec-device-name>/lightbar/userspace_control
		Date: August 2015
		KernelVersion: 4.2
		Description:
		This allows you to take the control of the lightbar. This
		prevents the kernel from going through its normal
		sequences.

		What: /sys/class/chromeos/<ec-device-name>/lightbar/version
		Date: August 2015
		KernelVersion: 4.2
		Description:
		Show the information about the lightbar version.

		small nvram space on some EC implementations.

		STMPE ADC driver
		----------------

		Required properties:
		- compatible: "st,stmpe-adc"

		Optional properties:
		Note that the ADC is shared with the STMPE touchscreen. ADC related settings
		have to be done in the mfd.
		- st,norequest-mask: bitmask specifying which ADC channels should _not_ be
		requestable due to different usage (e.g. touch)

		Node name must be stmpe_adc and should be child node of stmpe node to
		which it belongs.

		Example:

		stmpe_adc {
		compatible = "st,stmpe-adc";
		st,norequest-mask = <0x0F>; /* dont use ADC CH3-0 */
		};

		STMicroelectronics STPMIC1 Onkey

		Required properties:

		- compatible = "st,stpmic1-onkey";
		- interrupts: interrupt line to use
		- interrupt-names = "onkey-falling", "onkey-rising"
		onkey-falling: happens when onkey is pressed; IT_PONKEY_F of pmic
		onkey-rising: happens when onkey is released; IT_PONKEY_R of pmic

		Optional properties:

		- st,onkey-clear-cc-flag: onkey is able power on after an
		over-current shutdown event.
		- st,onkey-pu-inactive: onkey pull up is not active
		- power-off-time-sec: Duration in seconds which the key should be kept
		pressed for device to power off automatically (from 1 to 16 seconds).
		see See Documentation/devicetree/bindings/input/keys.txt

		Example:

		onkey {
		compatible = "st,stpmic1-onkey";
		interrupt-parent = <&pmic>;
		interrupts = <IT_PONKEY_F 0>,<IT_PONKEY_R 1>;
		interrupt-names = "onkey-falling", "onkey-rising";
		power-off-time-sec = <10>;
		};
