soc: mediatek: Add MediaTek DVFS Resource Collector (DVFSRC) driver

2024-10-21T14:00:51+00:00

The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a Hardware module used to collect all the requests from both software and the various remote processors embedded into the SoC and decide about a minimum operating voltage and a minimum DRAM frequency to fulfill those requests in an effort to provide the best achievable performance per watt. This hardware IP is capable of transparently performing direct register R/W on all of the DVFSRC-controlled regulators and SoC bandwidth knobs. This driver includes support for MT8183, MT8192 and MT8195.

soc: mediatek: mtk-socinfo: depends on CONFIG_SOC_BUS

2024-04-23T10:09:12+00:00

The mtk-socinfo driver uses symbols 'soc_device_register' and 'soc_device_unregister' which are part of the bus driver for System-on-Chip devices. Select SOC_BUS to make sure that driver is built and the symbols are available.

pmdomain: mediatek: Move Kconfig options to the pmdomain subsystem

The Kconfig options belongs closer to the corresponding implementations, hence let's move them from the soc subsystem to the pmdomain subsystem. Cc: Matthias Brugger Cc: AngeloGioacchino Del Regno Cc: Signed-off-by: Ulf Hansson

soc: mediatek: Kconfig: Add MTK_CMDQ dependency to MTK_MMSYS

2023-04-11T15:15:10+00:00

The mtk-mmsys and mutex drivers do have a dependency on MTK_CMDQ, even though both can work with *or* without it: since CMDQ support can be enabled either as module or as built-in, it is necessary to add a depends rule in Kconfig, so that we disallow building both mtk-mmsys and mtk-mutex as built-in if mtk-cmdq-helper is built as a module, otherwise obvious linker issues appear.

soc: mediatek: Introduce mediatek-regulator-coupler driver

2023-01-30T10:27:49+00:00

This driver currently deals with GPU-SRAM regulator coupling, ensuring that the SRAM voltage is always between a specific range of distance to the GPU voltage, depending on the SoC, necessary in order to achieve system stability across the full range of supported GPU frequencies.

soc: mediatek: Let PMIC Wrapper and SCPSYS depend on OF

2022-08-25T13:20:31+00:00

With the following configuration options: CONFIG_OF is not set CONFIG_MTK_PMIC_WRAP=y CONFIG_MTK_SCPSYS=y we get the following build warnings: CC drivers/soc/mediatek/mtk-pmic-wrap.o drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=] drivers/soc/mediatek/mtk-pmic-wrap.c:1953:34: warning: ‘of_slave_match_tbl’ defined but not used [-Wunused-const-variable=] CC drivers/soc/mediatek/mtk-scpsys.o drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=] Looking at the code, both drivers can only bind to OF-defined device nodes, so these drivers are useless without OF and should therefore depend on it. Also drop of_match_ptr() from both drivers. We already know what it will resolve to, so we might as well save cpp some work. Developers or QA teams who wish to test-build the code can still do so by enabling CONFIG_OF, which is available on all architectures and has no dependencies.
