[PATCH v18 1/3] dt-bindings: i2c: aspeed,i2c.yaml: add transfer-mode and global-regs properties and update example

Hi Ryan,

OK, but the ast2400 and ast2500 I2C peripherals - which this binding
also describes - do not have that facility. Given the 2600 is a distinct
peripheral (as discussed on the v16 series), this would seem to warrant
a distinct binding.

Should this be split out into an ast2600-specific binding, to reflect
that it is different hardware? The reference to the global registers and
transfer modes would then be added only to the ast2600-i2c-bus binding.

Cheers,


Jeremy
