[PATCH 2/3] staging: iio: light: of: Fix vendor prefix of isl29018

[Laxman Dewangan]

ISL29018 is from Intersil Corporation and the vendor prefix
for this part should be "isl", at least not "invn" for OF
compatibility.

Fine with me.  Not really my domain other than where it sits though!
Send on to Greg when you get acks from device tree side.

(There were a ton of irrelevant people CC'd on this patch; I cut them
out, but kept the lists in case anyone was interested in the replies.
The most relevant list, linux-tegra, also wasn't CC'd)

I don't think the label "isl29018:" serves any purpose; nothing else
needs to refer to this node.

I note from http://patchwork.ozlabs.org/patch/132936/ that:

a) Perhaps the vendor prefix should be "isil" not "isl". Olof, can you
please comment here?

b) There's an interrupt signal connected to the device. Can you please
add that, irrespective of whether the driver uses it.

c) This device is also present on Seaboard. Can you update
tegra-seaboard.dts too? You can find the relevant bus from the link above.

Thanks.

Will do.

I will wait for finalizing the vendor prefix before creating the next patch.
This will impact the driver also.

Any comments on this? I think "isil" is good as it is the symbol in 
nasdaq also: Intersil Corporation (ISIL).
If no objection than I can send my next version of patch ;)

Adding LinusW, Mark and Grant if they have any comment here.

Yes, the idea is to use stock ticker symbols where possible, so it
sounds like isil is the way to go.

Like most of the kernel people I don't care much about that as long
as the string is unique ... your pick is likely the best.

The standard practice is to use stock tickers, but if companies aren't public
then there isn't much you can do. Like Linus said, use your best judgement and
taste and that's really all we can ask for. :)
