*** BLURB HERE *** This series is based on linux-next, tag: next-20250206. Vcore DVFS feature need know the current DDR data rate. Add MediaTek DRAMC driver to provide an interface that can obtain current DDR data rate. --- Changes in v2: - Remove pr_info and pr_err, use dev_err or dev_err_probe to print error message; - Replace module_init by module_platform_driver; - Remove unnecessary global variables; - Change fmeter-verison to platform data; - Remove mtk-dramc.h; - Refine compatible to "mediatek,mt8196-dramc"; - Refine CONFIG name to MEDIATEK_MC; - Fix yaml build errors, remove unnecessary properties on yaml file.
