The "n" factor of the PLL_PERIPH0 clock is using the usual +1 encoding, so we need to adjust the register value before doing the calculation.
This fixes the MMC clock setup on those SoCs, which could be slightly off due to the wrong parent frequency: mmc 2 set mod-clk req 52000000 parent 1176000000 n 2 m 12 rate 49000000 Signed-off-by: Andre Przywara <[email protected]> --- arch/arm/mach-sunxi/clock_sun50i_h6.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/mach-sunxi/clock_sun50i_h6.c b/arch/arm/mach-sunxi/clock_sun50i_h6.c index 492fc4a3fca..a947463e0a5 100644 --- a/arch/arm/mach-sunxi/clock_sun50i_h6.c +++ b/arch/arm/mach-sunxi/clock_sun50i_h6.c @@ -94,7 +94,7 @@ unsigned int clock_get_pll6(void) int m = IS_ENABLED(CONFIG_MACH_SUN50I_H6) ? 4 : 2; uint32_t rval = readl(&ccm->pll6_cfg); - int n = ((rval & CCM_PLL6_CTRL_N_MASK) >> CCM_PLL6_CTRL_N_SHIFT); + int n = ((rval & CCM_PLL6_CTRL_N_MASK) >> CCM_PLL6_CTRL_N_SHIFT) + 1; int div1 = ((rval & CCM_PLL6_CTRL_DIV1_MASK) >> CCM_PLL6_CTRL_DIV1_SHIFT) + 1; int div2 = ((rval & CCM_PLL6_CTRL_DIV2_MASK) >> -- 2.17.5 -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
