Hi Arnd, Kevin and Olof,

This finally moves SROM controller and PMU code to separate
driver under drivers/soc/samsung.

Kind regards,
Krzysztof

  drivers: soc: Add support for Exynos PMU driver (2016-01-25 10:46:59 +0900)

----------------------------------------------------------------
A set of changes adding new drivers under drivers/soc/samsung:

1. Split code for handling SROM registers out of arm/mach-exynos
   in to separate SROM controller driver under drivers/soc/samsung.
   The driver will save and restore SROM registers during Suspend
   to RAM.

2. Add to this SROM controller driver support for bank configuration
   used by child devices. This allows usage of SMSC9115 Ethernet chip
   on SMDK5410 (Exynos5410) directly connected to SROM controller.

Hi,

OMAP has GPMC drivers under drivers/memory. I wonder if SROM should go there
too, since it's a quite similar bus.

I wish I get this feedback before, when we were discussing the SROM
patches. :/

Indeed this sounds reasonable. On some boards the omap-gpmc is used for
the same purpose: interfacing to smsc,lan9115 (like on SMDK5410).

Feel free to respin this without SROM now, so we can get the other pieces in
sooner and then revisit the SROM asyncronously. That'll remove the dependencies
on DT as well.

Okay, I'll rebase all drivers/soc branches and respin the pull request
so PMU driver and other stuff could go in.

BTW, just in case, although PMU stands for "Power Management Unit" I
don't think it should be placed under drivers/power because it is not a
avs/charger/battery/reset driver. Existing power-related drivers are
under driver/soc (bcm, dove, tegra).

Re-work of SROM drivers could be started on top of it.

Best regards,
Krzysztof
