Cover letter [PATCH 0/5] mmc: meson-gx: add cmd23 and descriptor chain mode
Apart from three minor improvements this patch series adds support for CMD23 mode and switches the driver to descriptor chain mode.
On my system with a 128GB eMMC card this increased the read performance from 10 - 15 MB/s to 140 MB/s.
Successfully tested on a Odroid C2 with custom uboot based on recent mainline uboot. Behavior might be different with vendor uboot.
