A lot of this looks very similar to reset-microchip-sparx5.c. PROTECT_REG is 0x88 rather than 0x84, but actually using the value is the same. SOFT_RESET_REG is identical. So rather than adding a new driver, maybe you can generalize reset-microchip-sparx5.c, and add a second compatible string? Andrew
