    The comment doesn't match the essence of patch.

    Why not just clk_get(&pdev->dev, NULL)?

clk_get_sys uses the clkdev lookup table, which is added by this series.
it makes the clock code consistent throughout the lantiq related files.
we use clk connections other places, which we cannot reference with
clk_get that easily

    clk_get() does the same, indirectly.

    clkdev assumes you don't need to use connection ID if the clock is bound to 
be matched by device ID via the lookup table. clk_get() is a common case when 
using clkdev, that's why your use of clk_get_sys() stands out as something 
unusual. I'll have to have a look at your lookup tables...
