That's why I added the ahb entry in my suggestion. > [3:2] 1 esdhc1_clk_root eSDHCv2_1 > > For i.MX53: > 1–0 CG0 esdhc1_ipg_hclk: affects ipg_clk and hclk inputs of ESDEHC-1 (esdhc1_clk_enable) > 3–2 CG1 esdhc1_perclk: affects ipg_clk_perclk input of ESDEHC-1 (esdhc1_serial_clk_enable) > > Table 18-3 (Output clocks from CCM) in the iMX53RM shows that > ESDHCv2-1's ipg_clk_perclk is esdhc1_clk_root, so the clock structure > does seem to be the same here, between i.MX50 and i.MX53… That's correct. The esdhc clocks seem to differ.
