Please clarify the frequency of reference clock of MMC controller of AM3358 to generate mmc_clk signal.
I think it is 96MHz (OPP100) from PD_PER_MMC_FCLK,
but there is description about maximum 48MHz.
Reference document : SPRUH73J
18.1.1 MMCHS Features
Clock support – 96-MHz functional clock source input
18.2.2 MMCHS Clock and Reset Management
CLKADPI Functional clock : Max 48 MHz
18.5.1.18 SD_SYSCTL Register
CLKD
These bits define the ratio between a reference clock frequency (system dependant) and the output clock frequency on the mmc_clk pin of either the memory card
