Here's a small patch series that adds support for the On Chip MEMory
(OCMEM) and msm8974 interconnect support to qcom_defconfig and to
qcom-msm8974.dtsi. The OCMEM driver is already in linux-next and it
looks like the interconnect support should be merged soon:

I have some work in progress patches for the HDMI bridge that's found
on the Nexus 5 and this series adds the necessary driver to
qcom_defconfig.

ARM: qcom_defconfig: add ocmem support
ARM: qcom_defconfig: add msm8974 interconnect support
ARM: qcom_defconfig: add anx78xx HDMI bridge support
ARM: dts: qcom: msm8974: add ocmem node
ARM: dts: qcom: msm8974: add interconnect nodes

We want to change it from tristate to bool [1].
