I'll fixup s/ead/lead/ here.

If it's ok with you Gregory, I'll amend this hunk as follows: or "marvell,mv78230-i2c" or "marvell,mv78230-a0-i2c" Only use "marvell,mv78230-a0-i2c" for a very rare, initial version of the SoC which had broken offload support. Linux auto-detects this and sets it appropriately. thx, Jason.
