Convert dt-bindings pwm-fsl-ftm.txt to yaml format. Additional change during convert: - "big-endian" is not required property. - Add "sleep" to pinctrl-names. - Change pinctrl-NNN to pinctrl-0 and pinctrl-1. - Remove label "pwm0" in example.

|
description: |
|
|
The same FTM PWM device can have a different endianness on different SoCs. The
|
|
device tree provides a property to describing this so that an operating system
|
|
device driver can handle all variants of the device. Refer to the table below
|
|
for the endianness of the FTM PWM block as integrated into the existing SoCs:
|
|
|
|
SoC | FTM-PWM endianness
|
|
--------+-------------------
|
|
Vybrid | LE
|
|
LS1 | BE
|

LS2 | LE

|
|
Please see ../regmap/regmap.txt for more detail about how to specify endian
|
|
modes in device tree.
