Add the "syscon" binding to the "altr,sys-mgr" node. The clock driver can use the syscon driver to toggle the register for the SD/MMC clock phase shift settings. Signed-off-by: Dinh Nguyen --- v7: Use the standard "snps,dw-mshc" binding. Remove "altr,socfpga-sdmmc-sdr-clk". v6: Add documentation for "altr,socfpga-sdmmc-sdr-clk".
