[PATCH v3 7/9] ARM64: dts: meson-gxbb: p20x: enable sdcard UHS modes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Enable sdcard UHS modes, up to SDR50, on p20x based boards.
While the s905 supports SDR104 mode, it appears that the PCB of p20x
based boards can't cope with a rate as high as 200Mhz.
