reset: reset-meson: Add support for Amlogic T7 SoC reset controller

2024-09-02T10:09:17+00:00

There are 7 sets of Reset Source in Amlogic T7 SoC reset controller, and the offset between base and level registers is 0x40. Add a new compatible string and struct meson_reset_param to support the reset controller on T7 SoC.

reset: meson: remove unneeded call to platform_set_drvdata()

2023-08-08T13:31:00+00:00

This function call was found to be unnecessary as there is no equivalent platform_get_drvdata() call to access the private data of the driver. Also, the private data is defined in this driver, so there is no risk of it being accessed outside of this driver file.

reset: Explicitly include correct DT includes

2023-07-28T15:36:20+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.

Convert platform_get_resource(), devm_ioremap_resource() to a single call to Use devm_platform_ioremap_resource(), as this is exactly what this function does.

reset: meson: make it possible to build as a module

2020-11-16T16:05:29+00:00

In order to reduce the kernel Image size on multi-platform distributions, make it possible to build the reset controller driver as a module. This partially reverts commit 8290924e6878 ("reset: meson: make it explicitly non-modular").

reset: meson: enable level reset support on Meson8b

2018-02-16T14:32:09+00:00

Commit a5a10afe04ef ("reset: meson: add level reset support for GX SoC family") only enabled the level resets for the newer GX SoC family. However, the older 32-Meson SoCs (Meson8, Meson8b and Meson8m2) also support level resets using the same offset as the newer GX SoCs. This removes the separation between Meson8b and the GX SoCs from the reset-meson driver to enable the level resets also on Meson8b.
