Subject: [PATCH v2 0/9] Add support for Microsoft Surface System Aggregator Module
Hello,
Here is version two of the Surface System Aggregator Module (SAM/SSAM)
driver series, adding initial support for the embedded controller on 5th
and later generation Microsoft Surface devices. Initial support includes
the ACPI interface to the controller, via which battery and thermal
information is provided on some of these devices.
The previous version and cover letter detailing what this series is
about can be found at
https://lore.kernel.org/platform-driver-x86/20201115192143.21571-1-luzmaximilian@gmail.com/
This patch-set can also be found at the following repository and
reference, if you prefer to look at a kernel tree instead of these
emails:
https://github.com/linux-surface/kernel tags/s/surface-aggregator/v2
Thank you all for the feedback to v1, I hope I have addressed all
comments.
Regards,
Max
Note: This patch depends on
[PATCH v4] platform/surface: Create a platform subdirectory for
Microsoft Surface devices
which can be found at
https://lore.kernel.org/platform-driver-x86/20201009141128.683254-1-luzmaximilian@gmail.com/
and is currently in platform-drivers-x86/for-next.
Changes in v1 (from RFC, overview):
- move to platform/surface
- add copyright lines
- change SPDX identifier to GPL-2.0+ (was GPL-2.0-or-later)
- change user-space interface from debugfs to misc-device
- address issues in user-space interface
- fix typos in commit messages and documentation
- fix some bugs, address other issues
Changes in v2 (overview):
- simplify some code, mostly with regards to concurrency
- add architectural overview to documentation
- improve comments for documentation
- use printk specifier for hex prefix instead of hard-coding it
- spell check comments and strings, fix typos
- unify comment style
- run checkpatch --strict, fix these and other style issues
Changes regarding specific patches (and more details) can be found on
the individual patch.
