This looks like a huge hammer, and I think this will cause problems for some systems, especially where some clocks are on remote devices which need to be controlled via I2C buses. The generic part walks all root clocks in the system, and all children of those clocks. If we have clocks on an I2C device, then we could very well end up with a circular dependency - the I2C controller needs its clocks restored in order for control of the clocks on the I2C device to be accessible. So, I think this needs more thought - clocks are not just about core SoC clocks - and cracking this nut with such a big hammer is likely to cause regressions all over the place. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
