Subject: nfc: s3fwrn5: Remove wrong vendor prefix from GPIOs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1995c4cc3ae4070717b07d972e0ee66989375304;p=linux.git

nfc: s3fwrn5: Remove wrong vendor prefix from GPIOs

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 but still support deprecated
ones.
