[PATCH] staging: iio: isl29028: add isl29030 support

[Sebastian Reichel]

isl29030 is basically the same chip. The only difference
is the chip's first pin. For isl29028 its named ADDR0 and
can be used to change the chip's i2c address. For isl29030
on the other hand that pin is named Ials and is an analog
current output proportional to ALS/IR. This change is
irrelevant for the Linux driver.

This has been tested on Motorola Droid 4.

Hi Sebastian,

I moved this driver out of the staging directory earlier this week.
You'll need to base your patch off of IIO testing:

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git/log/?h=testing

Your patch should apply cleanly once you update the file path.

I did it rather than having this bounce around for a trivial rebase.

Applied to the togreg branch of iio.git and pushed out as testing of
the autobuilders to play with it.

Thanks,

Jonathan
