Thomas Petazzoni f571053152 clk: mvebu: add suspend/resume for gatable clocks ... This commit adds suspend/resume support for the gatable clock driver used on Marvell EBU platforms. When getting out of suspend, the Marvell EBU platforms go through the bootloader, which re-enables all gatable clocks. However, upon resume, the clock framework will not disable again all gatable clocks that are not used. Therefore, if the clock driver does not save/restore the state of the gatable clocks, all gatable clocks that are not claimed by any device driver will remain enabled after a resume. This is why this driver saves and restores the state of those clocks. Since clocks aren't real devices, we don't have the normal ->suspend() and ->resume() of the device model, and have to use the ->suspend() and ->resume() hooks of the syscore_ops mechanism. This mechanism has the unfortunate idea of not providing a way of passing private data, which requires us to change the driver to make the assumption that there is only once instance of the gatable clock control structure.
