platform/x86: wmi: Move WMI core code into a separate directory

2025-11-18T09:18:11+00:00

Move the WMI core code into a separate directory to prepare for future additions to the WMI driver. Also update the description of the Kconfig entry to better fit with the other subsystem Kconfig entries.

platform/raspberrypi: Destage VCHIQ interface

2025-11-09T02:24:20+00:00

Destage the VCHIQ interface driver to drivers/platform/raspberrypi. There is still the remaining TODO item of improving the documentation, which can be handled post destaging. Secondly, multimedia drivers like codec and ISP that rely on this interface need to be upstreamed. And lastly, the drivers that facilitate the shared memory between VideoCore and Linux, like the vc-sm-cma driver and vc_mem char driver also need to be upstreamed.

platform/arm64: build drivers even on non-ARM64 platforms

2024-06-24T15:22:15+00:00

The Kconfig for platforms/arm64 has 'depends on ARM64 || COMPILE_TEST'. However due to Makefile having just obj-$(CONFIG_ARM64) the subdir will not be descended for !ARM64 platforms and thus the drivers won't get built. This breaks modular builds of other driver drivers which depend on arm64 platform drivers.

platform: Add ARM64 platform directory

2024-03-25T14:48:04+00:00

Some ARM64 based laptops and computers require vendor/board specific drivers for their embedded controllers. Even though usually the most important functionality of those devices is implemented inside ACPI, unfortunately Linux doesn't currently have great support for ACPI on platforms like Qualcomm Snapdragon that are used in most ARM64 laptops today. Instead Linux relies on Device Tree for Qualcomm based devices and it's significantly easier to reimplement the EC functionality in a dedicated driver than to make use of ACPI code. This commit introduces a new platform/arm64 subdirectory to give a place to such drivers for EC-like devices. 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 Ilpo Järvinen) with additional review from Bryan O'Donoghue to represent ARM64 maintainers.

platform: Add Surface platform directory

2020-10-27T11:51:03+00:00

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.

Platform: OLPC: Add XO-1.75 EC driver

It's based off the driver from the OLPC kernel sources. Somewhat modernized and cleaned up, for better or worse. Modified to plug into the olpc-ec driver infrastructure (so that battery interface and debugfs could be reused) and the SPI slave framework.
