which is also part of next-20200108.
Changes brought in include:
- cleanup of pinmux node names
- addition of Security ID, MBUS, CSI, crypto engine, video codec,
pmu, and thermal sensor device nodes for both SoCs
- addition of deinterlacing engine device node on H3
- cleanup of RTC device node and addition of its clocks
- various board cleanups and improvements
- removal of pinmux node for GPIO lines
- cpufreq / DVFS
- HDMI output
- UART-based Bluetooth
- audio codec
- USB ports
- new boards
Most of the changes don't concern U-boot.
