From: Matthias Brugger <mbrugger@suse.com>

There is no strong reason for this to use CLK_OF_DECLARE instead of
being a platform driver. Plus, this driver provides clocks but also
a shared register space for the mediatek-drm and the mediatek-mdp
driver. So move to drivers/soc/mediatek as a platform driver.

Changes in v10:
- Renamed to be generic mtk-mmsys
- Add driver data support to be able to support diferent SoCs

Changes in v9:
- Move mmsys to drivers/soc/mediatek (CK)

Changes in v8:
- Be a builtin_platform_driver like other mediatek mmsys drivers.

Changes in v7:
- Free clk_data->clks as well
- Get rid of private data structure

regarding the merge strategy, I propose that CK takes it through his tree and
provides a stable branch in case I'll need to put some patches on top of the
drivers/soc part.

Makes sense?

Matthias

There are many dependencies in this series, so I would like to apply
this series to a tree together. I think mmsys driver is major of this
series, and this series does not conflict with Mediatek DRM tree now, so
I would like to apply this series to soc tree. How do you think?

CK
