Subject: [PATCH V4 1/2] dt-bindings: reset: imx7: Add support for i.MX8MM
From: Anson Huang <Anson.Huang@....com>
i.MX8MM can reuse i.MX8MQ's reset driver, update the compatible
property and related info to support i.MX8MM.
Signed-off-by: Anson Huang <Anson.Huang@....com>
---
Changes since V3:
- Add comments to those reset indices to indicate which are NOT supported on i.MX8MM.
