Here is some information about the Qualcomm SOC mainlining project.
[ this page is currently a stub ]
Contents
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
- 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 |
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. |

git trees
- git trees:
- Sony github integration ("next") tree: https://github.com/andersson/kernel/tree/next
- Sony maintains this tree by keeping patch sets for individual technology areas or features in separate git branches. We have an internal tool called 'splash', that is used to integrate the separate branches into a single integration branch (the "next" branch). This tool is available upon request, if you want to use the same workflow as Sony.

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)
