Merge branch 'reset/lookup' of git://git.pengutronix.de/git/pza/linux into clk-davinci
We need this to be able to use the reset_controller_add_lookup() API. * 'reset/lookup' of git://git.pengutronix.de/git/pza/linux: reset: modify the way reset lookup works for board files reset: add support for non-DT systems
