Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC support, there is a need of DT based implementation of PMU driver. This driver uses already existing DT binding information.

PMU support for ARM32 EXYNOS SoCs is heavily SoC dependent and there is very little code shared between diffirent SoCs. Unless PMU setup for Samsung ARM64 SoCs is similar to some existing ARM32 EXYNOS SoCs it may be better to just add a separate PMU driver for Samsung ARM64 SoCs. IOW it would be best to show that this patch series is really useful before merging it. When it comes to the current patches it would be better to do changes converting PMU support to be a platform driver first for the existing arch/arm/mach-exynos/pmu.c file and then move+rename this file in the separate patch. Currently the code changes are done at the same time as the code movement which makes them difficult to review/verify. There are also some minor issues with the new code: [...] > diff --git a/drivers/mfd/exynos-pmu.c b/drivers/mfd/exynos-pmu.c > new file mode 100644 > index 0000000..24abd9b > --- /dev/null > +++ b/drivers/mfd/exynos-pmu.c > @@ -0,0 +1,534 @@ > +/* > + * Copyright (c) 2014-2015 Samsung Electronics Co., Ltd. > + * http://www.samsung.com/ 2015?

We think it will be useful, but I will consider your point of making driver which should have common piece of code to address various EXYNOS SoCs.

Please see comments [1] from Tomasz figa for my PMU series on 5420 and 5260.

Please see comments [1] from Tomasz figa for my PMU series on > 5420 and 5260. > > [1] http://www.spinics.net/lists/arm-kernel/msg322724.html We thought of it, but as you know "arch/arm/mach-exynos/pm.c" has a lot of dependencies, not only on "mach/exynos" header files but also on "plat-samsung". Also we need to decide proper location for pm.c, I can think for "drivers/soc", what do you say? Seeing that there is a significant amount of work, we decided to keep this work as separate from pmu.c work.
