Yes, this is the IPU - rather a patch to fix this was not included for
the release, I applied it later:


commit c510f2e436008e55a50b063f2180cb1e63984224

    video: ipu_common: fix build error

    Some toolchains fail to build
    "clk->rate = (u64)(clk->parent->rate * 16) / div;"
    And the cast usage is wrong.

    Use the following code to fix the issue,
    "
      do_div(parent_rate, div);
      clk->rate = parent_rate;
    "
