DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.

The interrupt output of the controller, i.MX6Q has IRQ_HIGH which
|
|
will be triggered when temperature is higher than high threshold,
|
|
i.MX6SX and i.MX7S/D have two more IRQs than i.MX6Q, one is IRQ_LOW
|
|
and the other is IRQ_PANIC, when temperature is lower than low
|
|
threshold, IRQ_LOW will be triggered, when temperature is higher
|
|
than panic threshold, IRQ_PANIC will be triggered, and system can
|
|
be configured to auto reboot by SRC module for IRQ_PANIC. IRQ_HIGH,
|
|
IRQ_LOW and IRQ_PANIC share same interrupt output of controller.
