Re: [PATCH v2 00/33] thermal: exynos: convert the driver to use per-SoC type operations
Hi Eduardo, Hi, This patch series replaces the hardware registers abstractions in the Exynos thermal driver by the usage of per-SoC type operations. Such solution provides simpler, easier to understand code and allows removal of ~250 LOCs (~11% of the whole source code) from the driver. Some other driver improvements are now also possible thanks to these changes but are scheduled at later time (like consolidating code for clearing IRQs using INTCLEAR register). The patchset should not cause any functionality changes. This means that unless there are some bugs in the patches itself there should be no behavior changes for the driver (this also includes lack of changes in the way hardware is accessed by the driver). All testing was done on (Exynos4412 SoC based) ODROID U3 board (some additional patches are needed to make the Exynos thermal driver work on this hardware).

Good! I think the driver is a bit confusing because it has two ways of checking features: soc based and feature flag based. Thus, removing one is a good step. Such solution provides simpler, easier to understand code and Well, that is arguable. IMO, the feature based solution is naturally easier to understand as while reading the code, you think about the feature not about chip / IP/ SoC versions. Besides, having soc based approach spreads many if's in your code base. Anyways, so far no one working in the Exynos code base has nacked your proposal. Apart from that, the issue I had with it, as I mentioned, was the fact that it currently has two ways of representing / checking features. That is for sure the major issue. allows removal of ~250 LOCs (~11% of the whole source code) from the driver. Some other driver improvements are now also possible thanks to these changes but are scheduled at later time (like consolidating code for clearing IRQs using INTCLEAR register). I am not sure I get your point here. I understand you are basing new changes in the code on top of this series, but I don't see how this refactoring could enable other feature implementions. The patchset should not cause any functionality changes. This means that unless there are some bugs in the patches itself there should be no behavior changes for the driver (this also includes lack of changes in the way hardware is accessed by the driver). All testing was done on (Exynos4412 SoC based) ODROID U3 board (some additional patches are needed to make the Exynos thermal driver work on this hardware). Is it possible to spread testing here? I would like to have coverage for all supported chip versions. The reasoning is because the driver supports more than Exynos4412, and the amount of changes are considerably big. One thing I can do is to start testing in linux-next on this code. Thus, I can merge it in my -next branch (which includes my -linus and -fixes branches). But so far, it would not be queued. My proposal is that these changes will be sent only for the 3.19 merge window though. For 3.18 -rc's I believe it is too late. However, to get it into 3.19, I request you to provide the testing in all supported chips, as I mentioned. Do you think it is doable before Linus opens 3.19 merge window?
