Subject: [PATCH v4 07/13] media: imx8-isi: Add support for i.MX8QM and
i.MX8QXP
From: Robert Chiras <robert.chiras@....com>
Add compatibles and platform data for i.MX8QM and i.MX8QXP platforms.
i.MX8QM's IER register layout is difference with i.MX8QXP.

---
Change from v3 to v4
- fix i.MX8QMP ier register layout
- Remove clk-names array
- Change 8QXP channel number to 6
change from v2 to v3
- none
change from v1 to v2
