Merge tag 'omap-for-v4.6/dt-ti81xx-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Enable dm814x and dra62x clock driver. This branch has a dependency to the clk-ti branch from the Linux clk tree for the ADPLL clock driver. Otherwise things won't keep booting properly when we flip over to use the clock driver instead of fixed clocks set up by the bootloader. * tag 'omap-for-v4.6/dt-ti81xx-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Add clocks for dm814x ADPLL
