I am not able to find how the GPIO number is calculated.
I want to export the GPIO4_09 pin in linux user space considering T1042 Processor Pin diagram .
I have done the calculation for IMX series which are like :
GPIO0_5 --> Linux number is 0*32 + 5 = 5.
Can some one post the formulae for QORIQ T104x Series.
Thanks in Advance.
