The maximum divider value for DPLL4 M4 divider appears wrong. For most OMAP3 family SoCs this is 16, but it is defined as 32, which is maybe only valid for omap36xx. To avoid any overflows in trying to write this register, set the max to 16 for all omap3 family, except omap36xx. For omap36xx the maximum is set to 31, as it appears value 32 is not working properly.
