The patchset features several bugfixes, rework and upgrade for the meson-gx MMC driver. The main goal is to improve readability and enable new high speed modes, such as eMMC DDR52 and sdcard UHS modes up to SDR50 (100Mhz) While full speed SDR104 is stable with most cards, a few seems to require an even more precise tuning. For this, we'll probably have to implement per-line delay calibration.
