[PATCH 1/2] ARM: davinci: Move clock init after ioremap.

From: David Lechner
Date: Thu Apr 14 2016 - 15:14:13 EST


Some clocks (such as the USB PHY clocks in DA8xx) will need to use iomem.
The davinci_common_init() function must be called before the ioremap, so
the clock init is now split out as separate function.

v4 changes:

* no longer wrapping davinci_clk_init() since it does not return an error.
