The simple card call: asoc_simple_card_probe -> asoc_simple_card_dai_link_of -> asoc_simple_card_sub_parse_of -> ... clk = of_clk_get(args.np, 0); if (!IS_ERR(clk)) dai->sysclk = clk_get_rate(clk); The sysclk come from the first clock, then first clock is hclk_i2s in i2s for rk3036 dtsi. So, we can override the clocks to fit the simple card in here.
