This is common for all SoCs, can use it if there is a reset controller driver supported. > I am upstreaming another series for system clock reset. That's good > I think you should add how to use for this series base on [1]. Currently I test it on mt8195 based on ti-syscon reset driver, luckly this is transparent for our usb controller drivers; I could add patches to use this 'resets' property on mt8195/8186 if the below series are applied.
