This patch extends this with IORESOURCE_CLK which should be used to pass a clock string to the platform driver. This string points out which specific clock that should be used with clk_get() for a certain driver instance. Using a hard coded strings in the device driver won't do since we may have multiple instances of drivers that need to use different clocks.
