What's going on here? This file is used by all three boards. If you need to
distinguish one board's CPLD from another's, you'll have to do it somewhere
else. If the CPLDs are exactly the same and no distinction needs to be made,
then you don't need three compatible strings. Even then, you may wish to
specify the exact board as the first compatible string, but again you'll need
to patch that in elsewhere so that it actually matches the board
.
As the register set of CPLD for all three boards is same, I am thinking of
replacing this with t104srdb-cpld
compatible = "fsl,t104xrdb-cpld","
Is this OK?
