Subject: [PATCH net-next 0/5] Add PPS support to am65-cpts driver
Date: Wed, 11 Jan 2023 17:14:24 +0530 [thread overview]
Message-ID: <20230111114429.1297557-1-s-vadapalli@ti.com> (raw)
The CPTS hardware doesn't support PPS signal generation. Using the GenFx
(periodic signal generator) function, it is possible to model a PPS signal
followed by routing it via the time sync router to the CPTS_HWy_TS_PUSH
(hardware time stamp) input, in order to generate timestamps at 1 second
intervals.
This series adds driver support for enabling PPS signal generation.
Additionally, the documentation for the am65-cpts driver is updated with
the bindings for the "ti,pps" property, which is used to inform the
pair [CPTS_HWy_TS_PUSH, GenFx] to the cpts driver. The PPS example is
enabled for AM625-SK board by default, by adding the timesync_router node
to the AM62x SoC, and configuring it for PPS in the AM625-SK board dts.
