I got:

drivers/clk/imx/clk-pllv4.c:152:15: warning: symbol 'imx_clk_pllv4' was not declared. Should it be static?
drivers/clk/imx/clk-pfdv2.c:166:15: warning: symbol 'imx_clk_pfdv2' was not declared. Should it be static?
drivers/clk/imx/clk-divider-gate.c:174:15: warning: symbol 'imx_clk_divider_gate' was not declared. Should it be static?
drivers/clk/imx/clk-composite-7ulp.c:22:15: warning: symbol 'imx7ulp_clk_composite' was not declared. Should it be static?

which I can fix easily by throwing in clk.h into each file.
