Overview

Here is some information about the Qualcomm SOC mainlining project. On this page are currently some lists of different IP SoC IP blocks or functional areas, with status for each one.

Project List

July 2015

List of items "in flight" (as of July 2015)

June 2014

List of items that need to be mainlined, or are "in flight" (as of June, 2014):

  • regulators - Josh Cartwright?, Bjorn Andersson?
  • clocks - Stephen Boyd
  • RPM
  • SD Card Controller - Srinivas Kandagatla
  • 8084 clock controller - Georgi Djakov
  • dma engine - Andy Gross
  • SOC-specific
    • 8084
    • 8974
  • USB support
    • USB host mode for HS port - Tim Bird
    • dwc3 (superspeed) USB driver
  • spmi - ??

Project Table

This might be too time-consuming to maintain?

Feature or Item Person Notes Link Last activity
SD card controller Srinivas Kandagatla This patch series adds Qualcomm SD Card Controller support in pl180 mmci

driver. QCom SDCC is basically a pl180, but bit more customized, some of the register layouts and offsets are different to the ones mentioned in pl180 datasheet. The plan is to totally remove the standalone SDCC driver drivers/mmc/host/msm_sdcc.* and start using generic mmci driver for all Qualcomm parts, as we get chance to test on other Qcom boards.

Status

[Figure out a metric for what remains to be done]

  • brainstorming ideas for metric to measure:
    • # of features out of tree (should be going down)
    • size of diff between latest msm tree and server it was based on? (should be going down)
    • linaro uses patch queue length (outstanding vs. already mainlined)
