The family of PCF857x-compatible chips describe 8-bit i2c i/o expanders.
Allow the user to specify names for the 8 gpio lines.

PCA9675 is 16-bit and has 16 outputs/

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)

This v3 patch applied for the next kernel (v6.4).
Don't expect to see it in linux-next until after the merge
window. I applied it so I don't forget about it later.
