Subject: [PATCH] regulator: rtmv20: Update DT binding document and property name parsing
From: ChiYuan Huang <cy_huang@...htek.com>
1. Add vendor suffix to all proprietary properties.
2. Fix typo.
3. Change lsw to normal property, not pattern property.
4. Due to item 1, modify source code for property parsing.
