The platform name and efuse parsing function pointer are only used while probing the device. Use them from the svs_platform_data struct instead. Reviewed-by:

Moving svs_platform_probe into driver probe function will allow us to reduce svs_platform members. This will be done in a follow-up patch. Reviewed-by:

If a compatible misses a match data entry, then something is wrong in the development phase, we don't need to check for that at runtime. Reviewed-by:

We only ever call the SoC specific probe function from svs_platform_probe. No need to carry that function in a global datastructure around. Reviewed-by:

Some projects might not support CONFIG_DEBUG_FS but still needs svs to be alive. Therefore, enclose debug cmd codes with CONFIG_DEBUG_FS to make sure svs can be alive when CONFIG_DEBUG_FS not supported. Signed-off-by:

svs_init01() calls pm_runtime_get_sync() and added fail path as svs_init01_finish to put usage_counter. However, pm_runtime_get_sync() will increment usage_counter even it failed. Fix it by replacing it with pm_runtime_resume_and_get() to keep usage counter balanced. Fixes: 681a02e9 ("soc: mediatek: SVS: introduce MTK SVS engine") Signed-off-by:

If svs init02 fail, it means we cannot rely on svs bank voltages anymore. We need to disable svs function and restore DVFS opp voltages back to the default voltages for making sure we have enough DVFS voltages.

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. Signed-off-by:

Add cmdq support for mtk-mmsys config API. The mmsys config register settings need to take effect with the other HW settings(like OVL_ADAPTOR...) at the same vblanking time. If we use CPU to write the mmsys reg, we can't guarantee all the settings can be written in the same vblanking time. Cmdq is used for this purpose. We prepare all the related HW settings in one cmdq packet. The first command in the packet is "wait stream done", and then following with all the HW settings. After the cmdq packet is flush to GCE HW. The GCE waits for the "stream done event" to coming and then starts flushing all the HW settings. This can guarantee all the settings flush in the same vblanking. Signed-off-by:

Some mmsys regs need to be set according to the HW engine binding to the mmsys simultaneously. 1. mtk_mmsys_merge_async_config: config merge async width/height. async is used for cross-clock domain synchronization. 2. mtk_mmsys_hdr_confing: config hdr backend async width/height. 3. mtk_mmsys_mixer_in_config and mtk_mmsys_mixer_in_config: config mixer related settings.

Currently, almost all MT63XX PMIC are documented mfd/mt6397.txt. Unfortunately, the PMICs haven't always similar HW sub-features. To have a better human readable schema, I chose to make one PMIC schema to match the exact HW capabilities instead of convert mt6397.txt to mediatek,mt63xx.yaml and put a bunch of properties behind "if contain ... then ..." - add interrupt property - change property refs to match with new yaml documentation Reviewed-by:
