For this purpose syscon driver is in the kernel. But regular syscon driver is initialized too late and platforms are trying to create specific code to handle it. For this purpose the series have been created to provide early syscon initialization and regmap creation first and then attaching device. The last patch is zynq specific patch to clear slcr driver and clock driver can profit from it too when clk regmap is ready. Also moving syscon driver from mfs should be consider.
