From: Thor Thayer <thor.thayer@xxxxxxxxxxxxxxx> Add MFD driver for SOCFPGA System Manager to handle System Manager calls differently for ARM32 vs ARM64. 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.
