Mon, 10 Jun 2024 08:57:32 +0000

soc: mediatek: Add MediaTek DVFS Resource Collector (DVFSRC) driverThe Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is aHardware module used to collect all the requests from both software and thevarious remote processors embedded into the SoC and decide about a minimumoperating voltage and a minimum DRAM frequency to fulfill those requests inan effort to provide the best achievable performance per watt.This hardware IP is capable of transparently performing direct register R/Won all of the DVFSRC-controlled regulators and SoC bandwidth knobs.This driver includes support for MT8183, MT8192 and MT8195.Co-Developed-by: Dawei Chien [Angelo: Partial refactoring and cleanups]Reviewed-by: Georgi Djakov Link: https://lore.kernel.org/r/20240610085735.147134-5-angelogioacchino.delregno@collabora.comSigned-off-by: AngeloGioacchino Del Regno List of files: /linux-6.15/drivers/soc/mediatek/Kconfig
