[PATCH 00/19] riscv: add initial support for the Allwinner V861 and Avaota F2

[Han Gao via B4 Relay]

The Allwinner V861 is a camera SoC with two XuanTie C907 harts. This
series adds the clock and pin controllers, the RTC clocks and the
device trees needed to boot the YuzukiHD Avaota F2 board to a serial
console.

Tested on the Avaota F2.
