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. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> --- 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 --- arch/arm/boot/dts/qcom-msm8660.dtsi | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)
