[Patch v2 08/11] Touch: DA9052 touchscreen driver

by ashishj3

This driver add support for DA9052 4-wire resistive ADC interfaced touchscreen controller. DA9052 is a MFD therefore this driver depends on DA9052 core driver for core functionalities.

Actually there're 2 problems: 1) detecting new upstream projects (there's script for that, but not expected to be run automatically so far); 2) properly migrating our own components to Gerrit, - so far we just leave old repos in place to keep old releases fetchable, but I expect this to lead to a mess. Btw, projects in Gerrit are not deletable in normal way ;-). (One could hack on DB level, yeah.) > > Do I understand correctly that we have a mirror AND the Gerrit copy > of the repos? (/srv/git.linaro.org/git/android + /mnt/gerrit-mirror > respectively) Yes, we have Gerrit-served master repositories, plus we have workcopy checkout to perform merges with upstream. Well, those merges are not merges, but fast-forwards of upstream branch subset, it would be cool if git could do fast-forward from a repository to repository w/o working copy, but of course that wouldn't work in general case of merges and conflicts. > Also, a general choice with a generic mirroring service is whether we > try sharing the mirrored data effectively.

I'm not sure I follow exactly. Are you talking about sharing git pack data across repositories, knowing they're close forks of each other? I never heard about that, nor I think its worth being pursued, because there's enough complexity already. It can be handled on specific project level somehow, for example Linaro codebase is a proper superset of AOSP, with fetching Linaro tree, one would have (easily separatable) access to both AOSP and Linaro code (technically, not politically). > Another problem I see with our current usage is that the branch names > keep changing, for instance linaro_android_2.3.5, and because this is > where we get manifests from, it might be tricky hardcoding this into > the mirroring service.

Yes. Please note that I personally consider it flawed experiment. It would have its limited usage, but to claim it's generally-suitable solution, it would need lot of testing. (With all these experiments, I got feeling that magic that repo does is very well thought, and keeps acceptable performance when dealing with truly enormous Android codebase at shaky equilibrium, so changing seemingly small thing can drop checkout speed twice for example). > > Yes, that's for sure a way to go.

No, I'm saying that I have intuitive suspicions that it may affect performance, so we'd rather take necessity of performance and load tests for this work seriously. And if performance degradation against reference design (repo) will be proven, think what to do about it. > Do we know in > which ways? avoiding useless branches I guess?

It's good when buildd > and developer builds look alike when possible. Well, I don't know. We for sure would want to (try to) improve build checkout time, and all ways should be considered. At repo is after just a tool which checks out a list of git repositories at specified revisions, so if we'd find more optimal way to do that (though likely more limited in other aspects), why not? > > > Another advantage is that there is now a python-git which can be > > > leveraged rather than wrapping the git commands in python as repo > > > does. > > That sounds too complicated, like another "quite complex and hairy > > for what it does in practice" ;-). > > Ah, so you've played with python-git and it sucks? No, I didn't mean that. I meant that before moving to using more intricate API level which would be allowed by using language binding, it would makes sent to try to implement it in terms of git pull/push, if that's not enough - git fetch, and only if still not enough - to employ even more complex solutions. > Fair enough, but > I did find it's a bit of a pity that repo has so much git wrapping > logic, not isolated at all, and probably fragile in the face of > changes to the host's git and gitconfig. > > > I guess you know that Google works (worked) slowly on integrating > > some kind of submodules support into repo (for exact purpose not > > known by me, I assume ditching manifests, but maybe just to support > > components with it).

[PATCH] ASoC: omap: convert per-board modules to platform drivers

by Mans Rullgard

This converts the per-board modules to platform drivers for a device created by in main platform setup. These drivers call snd_soc_register_card() directly instead of going via a "soc-audio" device and the corresponding driver in soc-core.

Memory Management Documentation effort

by Benjamin Gaignard

Hello, I'm writing documentation about CMA ( https://wiki.linaro.org/OfficeofCTO/MemoryManagement?action=AttachFile&do=v… ) and DMA_Buf ( https://wiki.linaro.org/OfficeofCTO/MemoryManagement?action=AttachFile&do=v… ) The goal is to explain outside the Linaro community how CMA and DMA_Buf works. I have tried to summarize my understanding in few slides and now I need you to review and comment this first draft. Additionnal info about who is doing what and when it will be delivered are welcome. Regards, Benjamin -- Benjamin Gaignard Multimedia Working Group Linaro.org <http://www.linaro.org/>* **│ *Open source software for ARM SoCs ** Follow *Linaro: *Facebook <http://www.facebook.com/pages/Linaro> | Twitter<http://twitter.com/#!/linaroorg> | Blog <http://www.linaro.org/linaro-blog/>
