Project List

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
  • SOC DT file? - Kumar Gala?
  • USB support

Project Table

This might be too time-consuming to maintain?

USB - msm_otg host mode Tim Bird I'm currently working on the pmic_id_irq, which require spmi support.

I got stuck on the DT EPROBE_DEFER support issue.

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.

Stakeholders

This is a list of parties who are (or should be) interested in the progress of this work:

  • Qualcomm
  • Code Aurora Forum
  • Linaro
  • Qualcomm Innovation Center
  • Sony
  • Samsung
  • LG
  • HTC
  • Motorola

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)
