Hi, Please add tsc2005 to board-rx51-peripherals.c. The code should have gone through the input queue according to [0], but only the touchscreen driver is part of the mainline linux kernel since 2.6.39-rc1. I attached the patch adding tsc2005 support to the rx51 board file, updated to apply cleanly against the mainline 3.1 kernel.
