Thanks for your patch!

"flag" is used for several purposes, which expected different types:
    - clk_init_data.flags is unsigned long,
    - The clk_divider_flags parameter of clk_hw_register_divider_table() is u8,
    - The clk_divider_flags parameter of __clk_hw_register_divider() is u8,
    - The flags parameter of __devm_clk_hw_register_mux() is unsigned long.

Actually the clk_mux_flags parameter of __devm_clk_hw_register_mux() is u8.

I guess u32 is fine for all.

when I'm talking to journalists I just say "programmer" or something like that.
