[PATCH v2 7/9] ARM64: dts: meson-gxbb: p20x: enable sdcard UHS modes
From: Jerome Brunet
Date: Mon Aug 21 2017 - 12:07:40 EST
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.
