Subject: [PATCH v3 2/6] dt-bindings: counter: new bindings for TI eQEP
Date: Sun, 1 Sep 2019 17:58:23 -0500 [thread overview]
Message-ID: <20190901225827.12301-3-david@lechnology.com> (raw)
In-Reply-To: <20190901225827.12301-1-david@lechnology.com>
This documents device tree binding for the Texas Instruments Enhanced
Quadrature Encoder Pulse (eQEP) Module found in various TI SoCs.
Signed-off-by: David Lechner <david@lechnology.com>
---
v3 changes:
- fixed style issues
- fixed generic node name
- (was suggested to drop descriptions since there is only one interrupt and one
clock, but I opted to keep them anyway)
v2 changes:
- convert to .yaml format
- rename clock to "sysclkout"
