[PATCH v4 2/4] arm64: dts: Add Qualcomm MSM8916 SoC and evaluation board dts

Thu Mar 12 10:56:25 PDT 2015


Add initial device tree support for Qualcomm MSM8916 SoC and MTP8916
evaluation board.  At the current time we only boot up a single processor.

Signed-off-by: Kumar Gala <galak at codeaurora.org>
---
v4:
* Added chosen node so we dont need to spec everything for earlycon
* fixed up timer node to armv8, dropped clock-frequency

v3:
* Removed qcom,msm-id and qcom,board-id
* Added top level compat for "qcom,msm8916-mtp-smb1360"

v2:
* Updated to dropping CONFIG_ARCH_QCOM_MSM8916
* Updated to use qcom-ids.h
