No, property "sunplus,pins" defined here is different from standard property "pins".
Mr. Linus Walleij asked me to add "sunplus," prefix.

I'll rename it to "sunplus,zerofunc" next patch.

I am sorry. I don't understand this comment.
Could I have more explanation? What is IMO?
The property "sunplus,zerofunc" is used to disable pins which are
enabled by boot-loader.
For example, boot-loader, U-Boot, enables a set of I2C pins. The I2C
pins keep enabled when Linux boot up. We can use "sunplus,zerofunc"
to disable the I2C pins in Linux.
