Paul can you elaborate on what that was about. I've felt a need for clock notifiers and we've cheated by using CPUfreq because it so happens that the clocking in system-wide and whenever the CPU freq change so may the other clocks. But if I put code into a PrimeCell MMC/SPI/I2C driver or whatever and use CPUfreq that's very unelegant, and for other platforms where the CPU freq don't change when this particular device clk freq change plain misleading. A clk pre/postchange notifier pair would really help and would make for elegant drivers that can handle clock freq transitions. Has anyone poked at this?
