Though no one is interested in this subject, anyway I found one solution; Set CM_WKUP_ADC_TSC_CLKCTRL in privileged mode, which I mean in the kernel module. I cannot figure out why this register is not modified in mmaped /dev/mem, however, in kernel module or kernel space, I can modify this register as |= 0x2.
Can anyone let me know why I encountered this problem? As far as I know only GPIO control registers need privileged mode to modify their values...
