Amlogic Meson6/8/8b/8m2 SoCs have two built-in MMC controllers: - SDIO (which is supported on mainline for a long time now but is limited to ~40MHz bus frequency) - SDHC (which supports up to HS-200 modes at ~100MHz bus frequency but for which we didn't have a driver)
Boards with NAND flash will now be able to use the SDIO controller for SDIO based wifi cards and the SDHC controller for the SD card slot. Boards with eMMC, SD card and SDIO wifi can only use two out of three MMC based devices for now until the MMC core and Meson SDIO driver gain support for multiple "mmc-slots" per controller.
Now that we have a driver for it, add the SDHC controller to meson.dtsi and wire up the eMMC connection on the Endless Mini EC-100 and the Odroid-C1.
