This patchset adds support for SD/MMC on JZ4780 based
platforms, such as the MIPS Creator CI20 board.
Most of the work has been done by Alex, Paul and Zubair,
while I've only prepared the upstream submission, cleaned
some patches, and written some commit logs where needed.
All praises should go to them, all rants to me.
The series is based on v4.16-rc6.
Changes from v3:
* Replaced callbacks with if/else magic to handle
the different register widths on versions of the SoC.
Changes from v2:
* Fix commit log in "mmc: dt-bindings: add MMC support to JZ4740 SoC"
Changes from v1:
* Reordered patches, fixes first, for easier backporting.
* Added Link and Fixes tags to patch "Fix race condition",
for easier backporting.
* Enabled the DMA in the dtsi for jz4780, dropped it from the ci20 dts.
* Reworded config and help user visible text.
* Reworded commit logs, using imperative.
* Re-authored my patches, as Collabora is partially
sponsoring them.
