I probably missed out updating the commit log. So please ignore it here, I should remove that from commit log. > Doesn't this mean these dts were broken between the changes to the > driver and the changes to the dts? > But the DTS updates are kept separate from driver updates because - DTS updates go into "Benoit's tree" or "Tony's tree" - whereas driver updates go into MTD tree. So, it was suggested in earlier patch revisions that I keep the driver and the DTS patches separate, so that there is no merge conflict between the trees when they are finally accepted. > I think the existing properties need to continue to be supoprted for > backwards compatibility.

Here following ecc-schemes are such legacy code, which are neither supported nor encouraged to use since long time. - OMAP_ECC_CODE_HAMMING_HW, - OMAP_ECC_CODE_HAMMING_DEFAULT, - OMAP_ECC_CODE_HAMMING_HW_ROMCODE Also backward compatibility is maintained by keeping a common symbol for all 3 above implementations OMAP_ECC_CODE_HAM1_HW I don't think there is a point to continue keeping these symbols in kernel driver if they are unused, and make driver bulky and unreadable. In actual it shouldn't matter to user what symbols I use inside the driver, what matters is backward compatibility right ? with regards, pekon -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
