[PATCH v42 0/6] critical clocks and handoff clocks
From: Michael Turquette
Date: Thu Feb 11 2016 - 16:19:42 EST
This series combines Lee's critical clock patches[0] plus some small
fixes and changes with a repost of my handoff clock patches[1]. Both
features are enabled by setting new flags on static clock data within
clock provider drivers.
In addition, there is a new function for setting the CLK_IS_CRITICAL
flag based on the presence of the clock-critical Device Tree property.
This DT property is not a part of the common-clock binding and must be
enabled on a per-binding basis (including adding that property to the
machine-specific binding description). Likewise the new function,
of_clk_detect_critical() must be called by either the clock provider
driver's probe or OF_CLK_DECLARE setup function.
