As has come up in the discussion around
[RFC PATCH] Add support for Microsoft Surface System Aggregator Module
it may make sense to add a Microsoft Surface specific platform
subdirectory. Andy has suggested drivers/platform/surface for that.
This series follows said suggestion and creates that subdirectory, as
well as moves Microsoft Surface related drivers over to it and updates
their MAINTAINERS entries (if available) accordingly.
This series does not modify any existing driver code, symbols, or help
text.
More details regarding maintainership can be found in
[PATCH v3 1/5] platform: Add Surface platform directory
Thanks,
Max

Changes in v2:
- Rebase onto linux-platform-drivers-x86/for-next to incorporate
changes in Maintainer file.
Changes in v3:
- Add separate MAINTAINERS entry for platform/surface
- Add Maximilian Luz as reviewer for platform/surface
For more details regarding changes, refer to the individual patches.

2.28.0
It may make sense to split the Microsoft Surface hardware platform
drivers out to a separate subdirectory, since some of it may be shared
between ARM and x86 in the future (regarding devices like the Surface
Pro X).
Further, newer Surface devices will require additional platform drivers
for fundamental support (mostly regarding their embedded controller),
which may also warrant this split from a size perspective.
This commit introduces a new platform/surface subdirectory for the
Surface device family, with subsequent commits moving existing Surface
drivers over from platform/x86.
A new MAINTAINERS entry is added for this directory. Patches to files in
this directory will be taken up by the platform-drivers-x86 team (i.e.
Hans de Goede and Mark Gross) after they have been reviewed by
Maximilian Luz.

Changes in v2:
- Do not create a separate MAINTAINERS entry for platform/surface.
Instead add drivers/platform/surface to x86 platform drivers entry.
This incorporates recent changes in the x86 platform driver
MAINTAINERS entry.
- Fix typo in commit message.
Changes in v3:
- Add separate MAINTAINERS entry for platform/surface
- Add Maximilian Luz as reviewer for platform/surface

I think in (1), (2) and (3) it makes sense to mimic Chrome, i.e. use

Thank you, will update this. FYI: The entry was mostly copied from the
X86 PLATFORM DRIVERS entry, so it should probably be updated there, too.

I agree with (2) and (3), but I'm not so sure about (1). For Chrome, the
entry is CHROME HARDWARE PLATFORM SUPPORT, so should I change it to
MICROSOFT SURFACE HARDWARE PLATFORM SUPPORT?
