patch "iio: adc: cc10001: Add delay before setting START bit" added to staging-linus

This is a note to let you know that I've just added the patch titled

iio: adc: cc10001: Add delay before setting START bit

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

Subject: iio: adc: cc10001: Add delay before setting START bit

According to hardware team there should be some delay after setting channel number, start mode and before setting START. Add a one microsecond delay for this purpose.
