[PATCH 00/14] mmc: meson-gx: driver fixups and upgrade

From: Jerome Brunet
Date: Fri Aug 04 2017 - 13:44:07 EST

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.

This series has been tested on gxbb-p200, gxbb-nanopi-k2 and
