The Qualcomm ipq6018 has apcs block, add compatible for the same.
Also, the apcs provides a clock controller functionality similar
to msm8916 but the clock driver is different.

Create a child platform device based on the apcs compatible for the
clock controller functionality.

These are easier to read if you ignore the 80-char limit.
Unless Jassi's object that is.

Add your entry on top, to maintain sort order.

Better use of_device_match_data() and get the string directly (or NULL).

I didn't apply the patch to look for myself, but please ensure to
maintain indentation to follow the parenthesis on the line before.

Add it one line up and you'll maintain partial sorting...

since Jassi has not objected your comment, I am making the change as per 
your suggestion.

As I checked there is no API called of_device_match_data(), the API 
of_device_get_match_data()

returns the data associated with the device and it cannot be used here.

please correct me if wrong.
