IMX7FLY-292 ARM: dts: imx7-phycore-som: limit eMMC clock frequency to 100MHz The following error occurs with some phyCORE-i.MX7 SOMs when writing to eMMC in HS400 mode: mmcblk2: error -84 transferring data, sector 340232, nr 256, cmd response 0x900, card status 0xb00 sdhci-esdhc-imx 30b60000.usdhc: warning! HS400 strobe DLL status REF not lock! Pending further investigation into HS400, this commit limits eMMC clock frequency as a workaround so that the strobe signal is not required and reading/writing succeeds without any errors on previously failing boards.
