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

v3:
- rebase on origin/master (fix for items moved to defconfig)
- update binman configuration to align with imx8mm binman
v2:
- rebase on origin/master (fix for items moved to defconfig)
- remove unused fdt_pack_reg function

Stefano / Fabio,
Could I get a review and/or status on this patch? I sent v1 back in september and had to rebase based on things moving to Kconfig twice now and have never gotten any responses. I have several patches pending that I haven't sent yet that depend on this one. I'm not sure if you are up to date on the pending imx patch backlog but I haven't seen any applied in a few days.
Best Regards,
Tim
