Subject: [PATCH v42 0/6] critical clocks and handoff clocks

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.

Lee Jones (3):
  clk: Allow clocks to be marked as CRITICAL
  clk: WARN_ON about to disable a critical clock
  clk: Provide OF helper to mark clocks as CRITICAL

Michael Turquette (3):
  clk: per-user clk prepare & enable ref counts
  clk: clk_put WARNs if user has not disabled clk
  clk: introduce CLK_ENABLE_HAND_OFF flag
