Subject: [PATCH] dt-bindings: microchip: atmel, at91rm9200-tcb: remove mandatory interrupts property
Date: Fri, 4 Feb 2022 10:14:46 +0200 [thread overview]
Message-ID: <20220204081446.474991-1-eugen.hristev@microchip.com> (raw)
The timer block can be used only to be read and to measure time in a polling
fashion. This can be used by Linux like this for example, or it can be used
by different projects which do not have interrupt controllers, or do not
wish to enable them (e.g. U-boot).
As DT is ABI, the binding should relate to all possible use cases and describe
the hardware and the requirements.
The interrupt is not a hard requirement for the timer to function in a
specific way.
Thus, choose to remove the interrupts property from the mandatory list of
properties.
