Hello, This series adds initial SoC support for the Samsung Exynos 9810 SoC and initial board support for Samsung Galaxy S9 phone (SM-G960F), codenamed starlte. The Exynos 9810 SoC is also used in S9 Plus (star2lte), Note 9 (crownlte), and perhaps more devices. Currently only Galaxy S9 DTS file is added but it should be fairly simple to add support for other devices based on this SoC, considering they're quite similar. The support added in this series includes: - cpus - pinctrl and gpio - simple-framebuffer This is enough to boot to a minimal initramfs shell. The preferred way to boot this device is by using a small shim bl called uniLoader [1], which packages the mainline kernel and DT and jumps to the kernel. This is done in order to work around some issues caused by the stock, and non-replacable Samsung S-Boot bootloader. For example, S-Boot leaves the decon trigger control unset, which causes the framebuffer to not refresh, so simple-framebuffer wouldn't work without a secondary loader. Ideally, there'll be a kernel driver for the display subsystem some day to resolve this issue.
