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

2023-07-11T13:30:09+00:00

To simplify with maintenance let's move the mediatek power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS. Cc: Matthias Brugger Cc: AngeloGioacchino Del Regno Cc: Signed-off-by: Ulf Hansson

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: SVS: introduce MTK SVS engine

2022-06-17T08:50:07+00:00

The Smart Voltage Scaling(SVS) engine is a piece of hardware which calculates suitable SVS bank voltages to OPP voltage table. Then, DVFS driver could apply those SVS bank voltages to PMIC/Buck when receiving OPP_EVENT_ADJUST_VOLTAGE.

soc / drm: mediatek: Move mtk mutex driver to soc folder

2021-02-04T14:55:46+00:00

mtk mutex is used by DRM and MDP driver, and its function is SoC-specific, so move it to soc folder. Signed-off-by: CK Hu Signed-off-by: Chun-Kuang Hu Acked-by: Matthias Brugger

soc: mediatek: add mt6779 devapc driver

2020-11-27T23:28:25+00:00

MediaTek bus fabric provides TrustZone security support and data protection to prevent slaves from being accessed by unexpected masters. The security violation is logged and sent to the processor for further analysis or countermeasures. Any occurrence of security violation would raise an interrupt, and it will be handled by mtk-devapc driver. The violation information is printed in order to find the murderer.

soc: mediatek: Add MediaTek SCPSYS power domains

2020-11-27T11:04:42+00:00

The System Control Processor System (SCPSYS) has several power management related tasks in the system. This driver implements support to handle the different power domains supported in order to meet high performance and low power requirements.

clk / soc: mediatek: Move mt8173 MMSYS to platform driver

2020-04-13T11:01:16+00:00

There is no strong reason for this to use CLK_OF_DECLARE instead of being a platform driver. Plus, MMSYS provides clocks but also a shared register space for the mediatek-drm and the mediatek-mdp driver. So move the MMSYS clocks to a new platform driver and also create a new MMSYS platform driver in drivers/soc/mediatek that instantiates the clock driver.

soc: Mediatek: Add SCPSYS power domain driver

2015-07-06T16:36:32+00:00

This adds a power domain driver for the Mediatek SCPSYS unit. The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control. For now this driver only adds power domain support, the more advanced features are not yet supported. The driver implements the generic PM domain device tree bindings, the first user will most likely be the Mediatek AFE audio driver.
