Thie patchset is a very experiment patchset to support the System Suspend feature of the Amlogic Meson GX SoCs.
These SoCs implements system suspend using a non-standard PSCI CPU_SUSPEND parameter to enter system suspend. A small driver is added to properly fill the platform_suspend_ops and make to correct SMC call. In order to wake up from an alarm, these SoCs have a special memory mapped register where an alarm time delay in seconds is stored. In order to reuse the RTC wakealarm feature, implement a fake RTC device that uses the system time to calculate a delay to write to the register. Note that this RFC is here to seek a better way to handle these platform specific features.
