Apparently, I remembered wrong. For mainline, arch/arm64/boot/dts/amlogic/meson-g12a-sei510.dts bus-width = <4>; cap-sd-highspeed; sd-uhs-sdr50; max-frequency = <100000000>; For vendor, common/arch/arm64/boot/dts/amlogic/mesong12a_sei.dtsi bus-width = <4>; cap-sd-highspeed; cap-mmc-highspeed; max-frequency = <100000000>; The vendor DTS has the following child node: sdio { pinname = "sdio"; ocr_avail = <0x200080>; /**VDD voltage 3.3 ~ 3.4 */ /* max_req_size = <0x20000>; */ /**128KB*/ max_req_size = <0x400>; card_type = <3>; /* 3:sdio device(ie:sdio-wifi), * 4:SD combo (IO+mem) card */ dmode = "pio"; }; Thus, it seems that the performance delta comes from driver architecture and different HW setup, rather than clock difference.
