Tanix TX6 box has a 32 GB eMMC module. With changes in this series, I
get following figures with hdparm -tT:
/dev/mmcblk2:
Timing cached reads: 1638 MB in 2.00 seconds = 818.44 MB/sec
Timing buffered disk reads: 376 MB in 3.01 seconds = 124.74 MB/sec
First patch fixes regulator node names. Second patch sets proper power
supplies to GPIO banks and third adds eMMC support.
Please take a look.
Best regards,
Jernej Skrabec
Changes from v1:
- added patch 1 (fixing regulator node names with "regulator-" prefix)
- fixed regulator node name in patch 2 (adding "regulator-" prefix)

Regulator node names don't reflect class of the device. Fix that by
prefixing names with "regulator-".

While there is no publicly available schematic of this board, it's not
hard to determine voltage of GPIO port C, D and G (only ones which can
be set).
Port C and G are used for MMC/SDIO communication, so they use 1.8 V
power supply. It's not clear if port D is even used, but if it is, it's
pretty safe to assume it uses 3.3 V power supply. Value read from PIO
Group Withstand Voltage Mode Select register from within pre-installed
Android agrees with that assesment.
