your recipient-list is missing the clock maintainers+lists - sorry for
not noticing this earlier.

While the devicetree-maintainers may Review it, we expect the clock-
maintainers to actually apply all 4 clock-related patches.

Same comment is true for
[PATCH v6 2/8] clk: rockchip: add dt-binding header for rk3036
