- Kernel
- Power: VBUS_DET implementation prevents complete poweroff. USB2 uses the PMIC VBUS_DET circuit, and when VBUS is provided by the processor (USB2 in host mode), the USB2_VBUS signal connected to the PMIC generates a WAKE event. As a result, the PMIC powers the system back up as soon as the shutdown finishes.
- Display: When HDMI and LCD-018 are both enabled in the DTS, the LCD-018 display does not output data properly. The workaround is to enable one or the other, and LCD-018 is currently the default.
