Subject: [PATCH v3 1/2] dt-bindings: gpio: nxp,pcf8575: add gpio-line-names
Date:   Thu,  9 Feb 2023 21:51:31 -0500

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.

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)
