There is no public documentation, but the u-boot GPL sources from the Amlogic BSP show that the DDR clock controller is identical on all three SoCs: #define CFG_DDR_CLK 792 #define CFG_PLL_M (((CFG_DDR_CLK/12)*12)/24) #define CFG_PLL_N 1 #define CFG_PLL_OD 1 // from set_ddr_clock: t_ddr_pll_cntl= (CFG_PLL_OD << 16)|(CFG_PLL_N<<9)|(CFG_PLL_M<<0) writel(timing_reg->t_ddr_pll_cntl|(1<<29),AM_DDR_PLL_CNTL); writel(readl(AM_DDR_PLL_CNTL) & (~(1<<29)),AM_DDR_PLL_CNTL); // from hx_ddr_power_down_enter: shut down DDR PLL writel(readl(AM_DDR_PLL_CNTL)|(1<<30),AM_DDR_PLL_CNTL); do { ... } while((readl(AM_DDR_PLL_CNTL)&(1<<31))==0) This translates to: - AM_DDR_PLL_CNTL[29] is the reset bit - AM_DDR_PLL_CNTL[30] is the enable bit - AM_DDR_PLL_CNTL[31] is the lock bit - AM_DDR_PLL_CNTL[8:0] is the m value (assuming the width is 9 bits based on the start of the n value) - AM_DDR_PLL_CNTL[13:9] is the n value (assuming the width is 5 bits based on the start of the od) - AM_DDR_PLL_CNTL[17:16] is the od (assuming the width is 2 bits based on other PLLs on this SoC) Add a driver for this PLL setup because it's used as one of the inputs of the audio clocks. There may be more clocks inside that clock controller - those can be added in subsequent patches.
