[PATCH] ARM: imx6: add support for SolidRun Hummingboard2
Lucas Stach
dev at lynxeye.de
Sun Jan 8 05:58:30 PST 2017
Aka: Hummingboard Edge and Hummingboard Gate
This currently only supports the pieces I was able to test:
- RTC
- SD card with UHS modes
- eMMC
- SGTL5000 sound
- All standard host USB ports
- mini PCIe
- IR receiver
- HDMI output
Functions routed out to the pin headers are not enabled and have
not been tested.
