I2C nodes should always have #address-cells and #size-cells defined.
Hence, ensure that all i2cX nodes have #address-cells and #size-cells
properties defined.

Right. BTW, have you seen some issue without this patch ?
Just curious what prompted you to create this patch and whether
it needs to be sent as fix during rc's.

Santosh

I think, it can wait for next. Without this patch warnings will
be produced in case of adding child node to the bus in DT:
Warning (avoid_default_addr_size): Relying on default #address-cells value for /soc/i2c at 2530800/pca at 20
Warning (avoid_default_addr_size): Relying on default #size-cells value for /soc/i2c at 2530800/pca at 20
I'll updated patch description and resend.
