Merge series "Fix vaud18 power leakage of mt6359" from Shane Chien <shane.chien@mediatek.com>
"Shane.Chien" <shane.chien@mediatek.com>: From: "Shane.Chien" <shane.chien@mediatek.com> This series of patches is to fix vaud18 power leakage problem. vaud18 will be enable only when mt6359 audio path is turned on. Change since v2: - fix dt-binnding syntex error Change since v1: - use dapm regulator supply widget for vaud18 control. - add vaud18 regulator property in mt6359 dt-binding.
