PATCH 1/2 ARM: dts: add EBI2 to the Qualcomm MSM8660 DTSI
This adds the external bus interface EBI2 to the MSM8660 device tree, albeit with status = "disabled" so that devices actually using EBI2 can turn it on if needed.
---
ChangeLog v3->v4:
- Rebase on kernel v4.9-rc1
- Bindings and driver are merged so should be clear to apply. ChangeLog v2->v3:
- Use the new #address-cells = <2> for indicating the CS in the first address cell
- Use the ranges property properly for defining the six different CS address windows
- Define CS3 to properly map over 128MB
- The EBI2 bindings are now ACKed by Rob Herring and a pull request to ARM SoC for both binding and driver is pending.
- This should be safe to merge for v4.9

Perhaps the node name should be more generic, like
external-bus at 1a100000
? I know, bikeshedding...
