[PATCH v6 0/2] Enable RPi header on j721e sk

[Rahul T R]

The following series of patches enables RPi header
on j721e sk. It is a 40 pin io expasion header which
brings out i2c5, ehrpwm 2,3 and some pins of gpio 0,1

v6:
   - Rebased to 6.1-rc1

v5:
   - Enable only gpio's and i2c on the RPi Header
     as per the discussion in the v4

v4:
   - Correct the node name in dt binding example

v3:
   - Change node name from clock to clock-controller
   - Add correct description for clock-controller node

v2:
   - Add full path for clock property $ref
   - Remove the discription for clock pattern property,
     since $ref is added
   - Remove the label in the example
   - Fix the indentation in the example

Now that the cleanups are in place, we'd need one additional rebase
please.
