soc: amlogic: canvas: fix device leak on lookup

2026-01-11T14:22:04+00:00

commit 32200f4828de9d7e6db379909898e718747f4e18 upstream. Make sure to drop the reference taken to the canvas platform device when looking up its driver data. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference. Also note that commit 28f851e6afa8 ("soc: amlogic: canvas: add missing put_device() call in meson_canvas_get()") fixed the leak in a lookup error path, but the reference is still leaking on success.

soc: amlogic: Explicitly include correct DT includes

2023-08-04T13:18:42+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

soc: amlogic: Move power-domain drivers to the genpd dir

To simplify with maintenance let's move the amlogic power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS.

drivers: meson: secure-pwrc: always enable DMA domain

Starting from commit e45f243409db ("firmware: meson_sm: populate platform devices from sm device tree data") pwrc is probed successfully and disables unused pwr domains. By A1 SoC family design, any TEE requires DMA pwr domain always enabled.

Merge tag 'driver-core-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2023-04-27T18:53:57+00:00

Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes.

soc: amlogic: meson-gx-socinfo: use new soc_device_register functionality to populate machine name

2023-03-29T10:21:23+00:00

A new fallback mechanism has been added to soc_device_register that populates machine with the DT model information if machine isn't set yet. This allows to remove this code here.
