2017-04-24 Thread Eric Anholt
For the Raspberry Pi's bindings, the power domain also implicitly turns on the clock and deasserts reset, but for the new Cygnus port we start representing the clock in the devicetree. v2: Document the clock-names property, check for -ENOENT for no clock in DT. v3: Drop NULL checks around clk
