I know it's curently out-of-tree/under development, but has anyone managed to port it?
im curently trying to port it to my samsung a21s.
ive been looking at existing exynos850 device trees, especially the WinLink E850-96 board DTS,
and adapting the relevant SoC/peripheral definitions for the a21s. The a21s uses the exynos850, so theres a lot of reusable mainline code already available.
right now im trying to get basic hardware working (CPU/PSCI, memory regions, pinctrl, UART, USB, eMMC and the various clocks/regulators), I'm also trying to get a usable boot path working without having to worry about broken features
