    dt-bindings: clock: Fix qcom,dispcc bindings for sdm845/sc7180 · 48cabc22
    Douglas Anderson authored
    The qcom,dispcc bindings had a few problems with them:
    
    1. They didn't specify all the clocks that dispcc is a client of.
       Specifically on sc7180 there are two clocks from the DSI PHY and
       two from the DP PHY.  On sdm845 there are actually two DSI PHYs
       (each of which has two clocks) and an extra clock from the gcc.
       These all need to be specified.
    
    2. The sdm845.dtsi has existed for quite some time without specifying
       the clocks.  The Linux driver was relying on global names to match
       things up.  While we should transition things, it should be noted
       in the bindings.
    
    3. The names used the bindings for "xo" and "gpll0" didn't match the
       names that QC used for these clocks internally and this was causing
       confusion / difficulty with their code generation tools.  Switched
       to the internal names to simplify everyone's lives.  It's not quite
       as clean in a purist sense but it should avoid headaches.  This
       officially changes the binding, but that seems OK in this case.
    
    Also note that I updated the example.
