Benoit,

This looks a lot better, thanks for turning it around so quickly!

My only general comment is just for the future. When submitting new versions of patches, please add a 'V2' inside the brackets on the Subject line. Or v3, or v4, or v14 in rare cases ;-)

It really helps us patch wranglers keep track of which version to apply.

One small comment below.

If that's the only thing left, I'll fix it up when I pull it in. No need to respin just for this.

Hi Jason

We should not really leave the i2c compatibility string as it is. Hopefully the OEM moved onto B1 stepping at some point. Although B1 devices will work with the workaround, you get better performance without it.

We should wait for Gregory to look at the quirk and soc-id code.

We should not really leave the i2c compatibility string as it is.

If you were to apply

ed2d859119f9 ARM: mvebu: Fix broken SoC ID detection

And then remove the -a0 i2c compatible string, does your board boot?

The referenced patch has been in mainline since v3.16-rc3, so you could just try that kernel w/o the compatible string.

thx,

Jason.

Also, the accepted convention is to add a blank line between the commit log body and the Signed-off-by line.

The Lenovo Iomega ix4-300d is a 4-Bay sata NAS with dual Gb, USB2.0 & 3.0, powered by a Marvell Armada XP MV78230 dual core CPU.

Hi Benoit

Please could you change the i2c compatible string, and retest including the two patches i just sent.

I confirm the V3 patch i sent (sorry for the first patch email which was wrong) is working with your patch

Quoted 4 lines

Once that is done, i think your patch is ready for acceptance. It is however a bit late for this cycle, so i guess Jason will keep hold of it until the next cycle.

Ok, jason, I did include the multi-line comment remarks in V3 patch, also I didn't resend the Lenovo vendor list patch, that was already acked I hope It's fine.
