Date: Thu, 11 Feb 2016 13:19:08 -0800 From: Michael Turquette <mturquette@...libre.com> To: linux-clk@...r.kernel.org Cc: lee.jones@...aro.org, sboyd@...eaurora.org, maxime.ripard@...e-electrons.com, maxime.coquelin@...com, geert@...ux-m68k.org, heiko@...ech.de, andre.przywara@....com, rklein@...dia.com, linux-kernel@...r.kernel.org, Michael Turquette <mturquette@...libre.com> 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.
