I can't reminder exact one. I grep some code

[IMX8MP_MEDIABLK_PD_LCDIF_1] = {
                .name = "mediablk-lcdif-1",
                .clk_names = (const char *[]){ "disp1", "apb", "axi", },
                .num_clks = 3,
                .gpc_name = "lcdif1",
                .rst_mask = BIT(4) | BIT(5) | BIT(23),
                .clk_mask = BIT(4) | BIT(5) | BIT(23),
                .path_names = (const char *[]){"lcdif-rd", "lcdif-wr"},
                .num_paths = 2,
        },

mask is more extenable and easily support more hardware in future. Change
to bit number have not big benefit.
