Subject: [PATCH 2/4] dt-bindings: net: nfc: s3fwrn5: Remove wrong vendor prefix from GPIOs
Date: Sat, 29 Aug 2020 16:29:46 +0200 [thread overview]
Message-ID: <20200829142948.32365-2-krzk@kernel.org> (raw)
In-Reply-To: <20200829142948.32365-1-krzk@kernel.org>
The device tree property prefix describes the vendor, which in case of
S3FWRN5 chip is Samsung. Therefore the "s3fwrn5" prefix for "en-gpios"
and "fw-gpios" is not correct and should be deprecated. Introduce
properly named properties for these GPIOs and rename the fw-gpios" to
"wake-gpios" to better describe its purpose.
