Wei Wang from Realsil contributed this driver in 2011. The following reasons lead to the removal: - This driver generates maintenance workload - Did not find minimal documentation on the web. - No blog entries about anyone using the rts5208 and rts5288 during the last years. - Did not find any device that may has it in and is still available on the market.
