This should be used in any of applicable examples.
Please refer to the DT changes included in the repository linked in the
cover letter, which should provide a clearer picture of how this
property is intended to be used. [0]
I'll also add a DT binding example in the next version to make the usage
more explicit.
Why do you new a new example? Why existing examples are not applicable?
typo: "Why do you need a new example?"
No, I wasn't planning to add a new example. I'll extend one of the
existing binding examples.
I also have doubts that this is per-device property. Your commit msg
suggests it is per controller.
This is a per-device property. It is consumed by the controller driver
only to locate and retrieve the offset of the PHY pattern partition
So with two devices on a bus, you need two separate partitions for tuning?
Each SPI NOR flash device needs a partition to store PHY tuning pattern.
