Re: Discussion on SOC device tree bindings

quoted

The thread started with discussion about the 5200 device tree binding
conventions, but has moved to a specific issue.  Now we are talking
about how to deal with shared registers.  ie. There are 2 I2C
controllers on the 5200, but they share one register.  How is that
best represented in the device tree?

  .../i2c-core/i2c-bus@0
              /i2c-bus@1

This describes two i2c buses under one i2c controller;
that's not the same thing.  OTOH, I suspect that's
closer to the real situation.  Grant?

Or something like that. Make one device that encloses them all.

It's the only way to do it, the shared register can be
in the "reg" property for one device node only.
