The SOCFPGA System Manager includes registers from several SOC peripherals. On ARM32, syscon handles this aggregated register grouping. Implement System Manager calls as regmap_mmio similar to syscon for ARM32 SOCFPGA systems. The ARM64 System Manager can only be accessed from priority level EL3 so this new MFD driver handles the calls to EL3. v2 Changes: Change socfpga_is_s10() to check compatible string. Add new compatible string for Stratix10 in bindings and add proper detection method. Replace base cast with resource_size_t member. Change s10_sysmgr_regmap_cfg to altr_sysmgr_regmap_cfg to be generic. Always use 4 byte width. Initialize the .reg_read and .reg_write in S10 case only. Remove call to syscon in 32bit ARM case and handle both ARM32 and ARM64 in of_sysmgr_register(). Replace IS_ERR_OR_NULL() with IS_ERR(). Remove compatible check functions except phandle function. v3 Changes: Create and register regmap in probe(). Lookup functions find registered regmap. Cleanup of header file. Fix copyright dates. Replace global pointer with traditional probe() methodology. v4 Changes: Add missing of_node_put().
