Now that drm/msm is converted over to use msm_get_clk() everywhere (that matters), which handles falling back to looking for a clock with the "_clk" suffix, we can remove "_clk" from the documentation so that new dts files added do not include "_clk" in the name. Previously we were doing this for the more recently upstreamed bindings but not for (nearly) all. Signed-off-by: Rob Clark <robdclark@gmail.com> Acked-by: Rob Herring <robh@kernel.org>
