[PATCH RESEND 2/2] ARM: da850: add the nand dev_id to the clock lookup table
From: Bartosz Golaszewski
Date: Fri Jan 13 2017 - 05:01:18 EST
The aemif driver can now access struct of_dev_auxdata (using platform
data).
Add the device id to the clock lookup table for the nand clock and
create a separate lookup table for aemif subnodes.
