Merge tag 'omap-for-v4.3/dt-dm814x' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
omap dts changes for minimal dm814x support for v4.3 merge window.
These changes make dm814x boot and adds minimal board support for
dm814x-evm and hp t410.
Note that to boot these depend on omap-for-v4.3/soc-signed branch,
but as dm814x support is currently broken, these can be merged
separately with the other dts changes.
* tag 'omap-for-v4.3/dt-dm814x' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: Add custom abort handler for t410
ARM: dts: Add minimal support for HP T410
ARM: dts: Add minimal dts support for dm8148-evm
ARM: dts: Add minimal clocks for dm814x
ARM: dts: Add minimal dm814x support
