Here's this patch updated with the above removed.
Ok. I fixed up Mike's email in case he wants to look at it. Looks fine to me though.
8< ------------- From: Tony Lindgren <t...@atomide.com> Date: Thu, 16 Jul 2015 01:55:57 -0700 Subject: [PATCH] ARM: OMAP2+: Add support for initializing dm814x clocks Let's add a minimal clocks for dm814x to get it booted. This is mostly a placeholder and relies on the PLLs being on from the bootloader. Note that the divider clocks work the same way as on dm816x and am335x.
