Hello Heiko, Quoting Heiko Stuebner (2016-02-11 05:00:02) > Yakir Yang (1): > clk: rockchip: rk3036: enable the CLK_IGNORE_UNUSED flag for hclk_vio_bus Thanks for sending the very readable PR. One question below, We'll likely have critical clock and handoff clock support merged in the next few days. I'm starting to audit any new CLK_IGNORE_UNUSED flag usage to see if it should use either of those two flags. Is the above patch a candidate? Thanks, Mike
