This documents the devicetree bindings for the SDHC MMC host controller found in Meson6, Meson8, Meson8b and Meson8m2 SoCs. It can use a bus-width of 1/4/8-bit and it supports eMMC spec 4.4x/4.5x including HS200 mode (up to 100MHz clock). It embeds an internal clock controller which outputs four clocks (mod_clk, sd_clk, tx_clk and rx_clk) and is fed by four external input clocks (clkin[0-3]). "pclk" is the module register clock, it has to be enabled to access the registers.
