Current aspeed-i2c driver could calculate a suited clock divisor and high/low cycles automatically, and it try to assign high/low periods with close number of cycles. Because of board schematic design, sometimes we need to manual tune i2c clock timing register to get longer high clock cycle to match hardware requirement, which is not supportted in current driver. In this patch series, we add new properties for manually assigning clock divisor, high clock cycles and low clock cycles.
