> The GW7902 is based on the i.MX 8M Mini / Nano SoC featuring:
>  - LPDDR4 DRAM
>  - eMMC FLASH
>  - Gateworks System Controller
>  - LTE CAT M1 modem
>  - USB 2.0 HUB
>  - M.2 Socket with USB2.0, PCIe, and dual-SIM
>  - IMX8M FEC
>  - PCIe based GbE
>  - RS232/RS485/RS422 serial transceiver
>  - GPS
>  - CAN bus
>  - WiFi / Bluetooth
>  - MIPI header (DSI/CSI/GPIO/PWM/I2S)
>  - PMIC
> To add support for the i.MX8M Nano GW7902:
>  - Add imx8mn-venice dts/defconfig/include
>  - Add imx8mn-gw7902 dts
>  - Add imx8mn-2gb lpddr4 dram configs
>  - Add misc support for IMX8M Nano SoC
>  - rename imx8mm-venice.c to venice.c as it is no longer imx8mm specific
>  - update README with differences for IMX8MN vs IMX8MM
