Now that the basic board support is available:
http://www.spinics.net/lists/linux-arm-msm/msg24533.html
and the associated clock changes have been picked up for next,
http://www.spinics.net/lists/linux-arm-msm/msg24499.html
Using V8 from Ritesh Harjani, with the additional changes provided to him for gcc-msm8994.c
[ http://www.spinics.net/lists/linux-arm-msm/msg24652.html ]
Additionally V9 of the RPM clock support [http://www.spinics.net/lists/linux-arm-msm/msg24211.html]
is needed.
At this point, "qcom,rpmcc-msm8916" was used successfully for testing of
the rpm clock controller. It has been marked as a TODO item in the DTS
and once the rpmcc clocks are added for 8992/8994 the needed change will
be made. i.e.) expect a follow up patch for rpmcc
Currently, the minimal regulators to verify / enable SDHCI functionality
have been added. While looking at the downstream code, I saw a few more
obvious entries so they have been included (completely untested). Hopefully
someone with the hardware docs can provide feedback and/or an individual
with better eye site than I who can ferret out more of the entries from
downstream.
The nonremovable "keyword/flag" was used to assess the reliability of the
initial mmc detection. When the flag is present in the DTS only 1 check
for SDHCI was made, without non removable it checks over and over again.
Without the workaround (patch 5/5) mmc/sdhci didn't get detected 8/20
times. When including the afore mentioned workaround MMC detection is
100% (35 boots) .
While at it, I took the liberty of re-tabifying include/dt-bindings/
clock/qcom,gcc-msm8994.h to make it look nice according to VIM using (:set list ).
Sorry emacs users, you are on your own.
Question:
In what DT-bindings txt file should the following, compatible = "qcom,rpm-msm8994";
be placed? (arch/arm64/boot/dts/qcom/msm8992.dtsi, rpm_requests node)
Obviously, this is a work in progress, and its progressing :-)

clk: gcc: Updates for SDHCI enablement
smd: Make packet size a constant
arm64: dts: Enable SDHCI for Nexus 5X (msm8992)
sdhci: dump vendor state and regs
sdhci: Add quirk for delayed IRQ ACK
