dt-bindings:iio:imu:st,lsm6dsx: txt to yaml conversion

Browse Source 
Straight forward conversion, but there are a few generic properties
in here like wakeup-source which should probably have schema in a
more generic location.

* ST_LSM6DSx driver for STM 6-axis (acc + gyro) imu Mems sensors
Required properties:
- compatible: must be one of:
"st,lsm6ds3"
"st,lsm6ds3h"
"st,lsm6dsl"
"st,lsm6dsm"
"st,ism330dlc"
"st,lsm6dso"
"st,asm330lhh"
"st,lsm6dsox"
"st,lsm6dsr"
"st,lsm6ds3tr-c"
"st,ism330dhcx"
"st,lsm9ds1-imu"
"st,lsm6ds0"
"st,lsm6dsrx"
"st,lsm6dst"
- reg: i2c address of the sensor / spi cs line
Optional properties:
- st,drdy-int-pin: the pin on the package that will be used to signal
"data ready" (valid values: 1 or 2).
- st,pullups : enable/disable internal i2c controller pullup resistors.
- drive-open-drain: the interrupt/data ready line will be configured
as open drain, which is useful if several sensors share the same
interrupt line. This is a boolean property.
(This binding is taken from pinctrl/pinctrl-bindings.txt)
If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or
IRQ_TYPE_EDGE_RISING a pull-down resistor is needed to drive the line
when it is not active, whereas a pull-up one is needed when interrupt
line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING.
- interrupts: interrupt mapping for IRQ. It should be configured with
flags IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
IRQ_TYPE_EDGE_FALLING.
- wakeup-source: Enables wake up of host system on event.
Refer to interrupt-controller/interrupts.txt for generic interrupt
client node bindings.
Example:
lsm6dsm@6b {
compatible = "st,lsm6dsm";
reg = <0x6b>;
interrupt-parent = <&gpio0>;
interrupts = <0 IRQ_TYPE_EDGE_RISING>;
};
