If the "divider" is included in MUX, the MUX would not be called "MUX". I don't know whether "divider" module exists or not. If it exists, it should be part of PLL or between PLL and MUX. wherever it was, the device tree binding is appropriate. The P3041RM shows exactly each PLL has 2 outputs which definitely have no "divider" at all. Regards, Yuantian ��.n��������+%������w��{.n����z�{��ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
