+* Broadcom Keypad Controller device tree bindings
+
+Broadcom Keypad controller is used to interface a SoC with a matrix-type
+keypad device. The keypad controller supports multiple row and column lines.
+A key can be placed at each intersection of a unique row and a unique column.
+The keypad controller can sense a key-press and key-release and report the
+event using a interrupt to the cpu.
+
+This binding is based on the matrix-keymap binding with the following
+changes:
+
+keypad,num-rows and keypad,num-columns are required.
+
+Required SoC Specific Properties:
+- compatible: should be "brcm,bcm-keypad"

+Input: sysrq reset sequence
+
+A simple binding to represent a set of keys as described in
+include/uapi/linux/input.h. This is to communicate a sequence of keys to the
+sysrq driver. Upon holding the keys for a specified amount of time (if
+specified) the system is sync'ed and reset.
+
+Key sequences are global to the system but all the keys in a set must be coming
+from the same input device.
+
+The /chosen node should contain a 'linux,sysrq-reset-seq' child node to define
+a set of keys.
+
+Required property:
+sysrq-reset-seq: array of Linux keycodes, one keycode per cell.
+
+Optional property:
+timeout-ms: duration keys must be pressed together in milliseconds before
+generating a sysrq. If omitted the system is rebooted immediately when a valid
+sequence has been recognized.
+
+Example:
+
+ chosen {
+ linux,sysrq-reset-seq {
+ keyset = <0x03
+ 0x04
+ 0x0a>;
+ timeout-ms = <3000>;
+ };
+ };
+
+Would represent KEY_2, KEY_3 and KEY_9.

+
+Optional properties:
+- linux,axis: the input subsystem axis to map to this rotary encoder.
+ Defaults to 0 (ABS_X / REL_X)

+ typical value for such devices.
+- rotary-encoder,relative-axis: register a relative axis rather than an

+- rotary-encoder,rollover: Automatic rollove when the rotary value becomes
+ greater than the specified steps or smaller than 0. For absolute axis only.
+- rotary-encoder,steps-per-period: Number of steps (stable states) per period.

+ 1: Full-period mode (default)
+ 2: Half-period mode
+ 4: Quarter-period mode
+- wakeup-source: Boolean, rotary encoder can wake up the system.
+

+- rotary-encoder,half-period: Makes the driver work on half-period mode.
+ This property is deprecated. Instead, a 'steps-per-period ' value should

+FocalTech EDT-FT5x06 Polytouch driver
+=====================================
+
+There are 3 variants of the chip for various touch panel sizes
+FT5206GE1 2.8" .. 3.8"
+FT5306DE4 4.3" .. 7"
+FT5406EE8 7" .. 8.9"
+FT5506EEG 7" .. 8.9"
+
+The software interface is identical for all those chips, so that
+currently there is no need for the driver to distinguish between the
+different chips. Nevertheless distinct compatible strings are used so
+that a distinction can be added if necessary without changing the DT
+bindings.
+
+
+Required properties:
+ - compatible: "edt,edt-ft5206"
+ or: "edt,edt-ft5306"
+ or: "edt,edt-ft5406"
+ or: "edt,edt-ft5506"
+
+ - reg: I2C slave address of the chip (0x38)
+ - interrupt-parent: a phandle pointing to the interrupt controller
+ serving the interrupt for this chip
+ - interrupts: interrupt specification for the touchdetect
+ interrupt
+
+Optional properties:
+ - reset-gpios: GPIO specification for the RESET input
+ - wake-gpios: GPIO specification for the WAKE input
+
+ - pinctrl-names: should be "default"
+ - pinctrl-0: a phandle pointing to the pin settings for the
+ control gpios
+
+ - threshold: allows setting the "click"-threshold in the range
+ from 20 to 80.
+
+ - gain: allows setting the sensitivity in the range from 0 to
+ 31. Note that lower values indicate higher
+ sensitivity.
+
+ - offset: allows setting the edge compensation in the range from
+ 0 to 31.
+
+Example:

+* TI - TSC ADC (Touschscreen and analog digital converter)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Required properties:
+- child "tsc"
+ ti,wires: Wires refer to application modes i.e. 4/5/8 wire touchscreen
+ support on the platform.
+ ti,x-plate-resistance: X plate resistance
+ ti,coordinate-readouts: The sequencer supports a total of 16
+ programmable steps each step is used to
+ read a single coordinate. A single
+ readout is enough but multiple reads can
+ increase the quality.
+ A value of 5 means, 5 reads for X, 5 for
+ Y and 2 for Z (always). This utilises 12
+ of the 16 software steps available. The
+ remaining 4 can be used by the ADC.
+ ti,wire-config: Different boards could have a different order for
+ connecting wires on touchscreen. We need to provide an
+ 8 bit number where in the 1st four bits represent the
+ analog lines and the next 4 bits represent positive/
+ negative terminal on that input line. Notations to
+ represent the input lines and terminals resoectively
+ is as follows:
+ AIN0 = 0, AIN1 = 1 and so on till AIN7 = 7.
+ XP = 0, XN = 1, YP = 2, YN = 3.
+- child "adc"
+ ti,adc-channels: List of analog inputs available for ADC.
+ AIN0 = 0, AIN1 = 1 and so on till AIN7 = 7.
+
+Optional properties:
+- child "tsc"
+ ti,charge-delay: Length of touch screen charge delay step in terms of
+ ADC clock cycles. Charge delay value should be large
+ in order to avoid false pen-up events. This value
+ effects the overall sampling speed, hence need to be
+ kept as low as possible, while avoiding false pen-up
+ event. Start from a lower value, say 0x400, and
+ increase value until false pen-up events are avoided.
+ The pen-up detection happens immediately after the
+ charge step, so this does in fact function as a
+ hardware knob for adjusting the amount of "settling
+ time".
+
+- child "adc"
+ ti,chan-step-opendelay: List of open delays for each channel of
+ ADC in the order of ti,adc-channels. The
+ value corresponds to the number of ADC
+ clock cycles to wait after applying the
+ step configuration registers and before
+ sending the start of ADC conversion.
+ Maximum value is 0x3FFFF.
+ ti,chan-step-sampledelay: List of sample delays for each channel
+ of ADC in the order of ti,adc-channels.
+ The value corresponds to the number of
+ ADC clock cycles to sample (to hold
+ start of conversion high).
+ Maximum value is 0xFF.
+ ti,chan-step-avg: Number of averages to be performed for each
+ channel of ADC. If average is 16 then input
+ is sampled 16 times and averaged to get more
+ accurate value. This increases the time taken
+ by ADC to generate a sample. Valid range is 0
+ average to 16 averages. Maximum value is 16.
+
+Example:
+ tscadc: tscadc@44e0d000 {
+ compatible = "ti,am3359-tscadc";
+ tsc {
+ ti,wires = <4>;
+ ti,x-plate-resistance = <200>;
