Summary	0000494: Offset in both directions is added to real touch on screen.
Description	Customer reports that an offset to the real touch is added. The offset occures in both directions (X,Y). The problem may occure direct after reboot or after several hours of working. If the problem occures after reboot it may disapaer after next reboot.
Steps To Reproduce	This problem seems to be related on the base clock used for lcdclk. 1. I establish that the problem occures with 33,25MHz but not with 28,22MHz. In the first case HCLK is used for base clock in the second case EPLL is used. 2. The i modified a test driver which never uses HCLK and the problem disapears (even by use 42MHz).
