[PATCH 0/5] Enable onboard SDHCI for Nexus 5X (msm8992)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




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 :-)
