Subject: [PATCH v3 1/2] dt-bindings: gpio: nxp,pcf8575: add gpio-line-names
The devices described in this binding represent 8-bit and 16-bit i2c i/o
expanders. Allow the user to specify names for up to 16 gpio lines.
Signed-off-by: Trevor Woerner <twoerner@...il.com>

changes since v2:
- expand maxItems to 16 to accommodate that some of the io expanders
covered in this schema are 16-bit (e.g. PCA9675)
changes since v1:
- the original said [PATCH 1/2], there is no 2/2
(or at least there wasn't back then)
