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.

Heiner Kallweit (5):
mmc: meson-gx: switch irq name to DT node name
mmc: meson-gx: improve response reading
mmc: meson-gx: use block mode also for just one block
mmc: meson-gx: add support for CMD23 mode
mmc: meson-gx: switch to descriptor chain mode
