[PATCH v2 0/4] ARM: qcom: add defconfig items and dts nodes

[PATCH v2 0/4] ARM: qcom: add defconfig items and dts nodes

[Brian Masney]

Here's a small patch series that adds some additional functionality
to qcom_defconfig and to qcom-msm8974.dtsi: interconnect, ocmem,
and HDMI bridge (defconfig only).

Some high-level changes since v1:
- Updated interconnect support. See patch #4 in this series for details.
- Dropped ocmem defconfig since that got merged.

Brian Masney (4):
  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

Georgi: Since Greg wants to allow compiling the interconnect support as
a module [1], should I change CONFIG_INTERCONNECT to be a module? Or
leave this as is? The GPU works fine with interconnect as a module on my
phone. I know it's more for the cpufreq case.

Andy/Bjorn: This series didn't get picked up for this upcoming merge
window. If it's too late for this window (which is fine), then I'll
hold off on resubmitting this until rc4 since I'll most likely have
more device tree changes by then.

This is the qcom_defconfig file, so it's fine to leave it =y. For the
multi-platform ones we should do the specific drivers =m, where
possible.

Thanks for the pointer, I don't think this is a good idea and did reply.

Sorry for missing it in the final preparation for v5.5.

I don't see anything among these patches that would require you to
repost the series, either we pick them up for another PR (although it's
rather late now) or we'll apply them as -rc1 lands (for v5.6).
