This patch series is a preparation for the MX8 Architecture improvement. As for IMX SCU based platforms like MX8QM and MX8QXP, they are comprised of a couple of SS(Subsystems) while most of them within the same SS can be shared. e.g. Clocks, Devices and etc. However, current clock binding is using SW IDs for device tree to use which can cause troubles in writing the common <soc>-ss-xx.dtsi file for different SoCs. This patch series aims to introduce a new binding which is more close to hardware and platform independent and can makes us write a more general drivers for different SCU based SoCs. Another important thing is that on MX8, each Clock resource is associated with a power domain. So we have to attach that clock device to the power domain in order to make it work properly. Further more, the clock state will be lost when its power domain is completely off during suspend/resume, so we also introduce the clock state save&restore mechanism.
For this patch series, missed to add Oliver's former tag: Tested-by: Oliver Graute <redacted> Regards Aisheng _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
