Changes v8 -> v9:
- rebase on master
- fix gpio active direction (suggested by Fabio Estevam)

- merge the rev A and B into one device tree based on the last rev B
because only the memory size change between the two rev currently
(suggested by Shawn Guo)
Changes v6 -> v7:
- rebase on master
- remove unneeded pinctrl-name (suggested by Shawn Guo)
- add reg to the node en-sd-pwr (suggested by Shawn Guo)
- use define for gpio polarity (suggested by Shawn Guo)
- remove the fake bus container for regulator (suggested by Shawn Guo)
Changes v5 -> v6:
- rebase on master
- split the previous patch series into series by subsystem
Changes v4 -> v5:
- fix missing signed off
Changes v3 -> v4:
- rebase on master
Changes v2 -> v3:
