The default clock parent of IMX8MM_CLK_DSI_PHY_REF is already IMX8MM_CLK_24M, so there is no need to set the parent-child relationship between them. The default clock rates for IMX8MM_SYS_PLL1_266M and IMX8MM_CLK_24M are already defined to be 266MHz and 24MHz respectively, so there is no need to define those clock rates. On i.MX8M[MNP] the samsung,pll-clock-frequency is not necessary, because the driver will read it from sclk_mipi which is also already set to 24MHz making it also redundant.
