Hey folks, This patchset adds device tree files for Exynos 2200 and Samsung Galaxy S22+. Exynos 2200 SoC is an ARMv8 mobile SoC found in the Samsung Galaxy S22 (r0s), S22+ (g0s), S22 Ultra (b0s) Add minimal support for that SoC, including psci, pmu, chipid, architecture timer and mct, pinctrl, clocks and usb. The devices using this SoC suffer from an issue caused by the stock Samsung bootloader, as it doesn't configure CNTFRQ_EL0. Hence it's needed to hardcode the adequate frequency in the timer node, otherwise the kernel panics. Another issue is that cpu2 and cpu3 fail to come up consistently, which leads to a hang later in the boot process. As A510 cores are clustered by two, it makes sense for both of these cpus to fail if there is a power issue. Disable them until the problem is figured out. Samsung Galaxy S22+ (SM-S906B), codenamed g0s, is a mobile phone from 2022. It features 8GB RAM, 128/256GB UFS 3.1, Exynos 2200 SoC and a 1080x2340 Dynamic AMOLED display. Further platform support will be added over time. I expect [1], [2], [3], [4], [5], [6] to be merged before this patchset because it relies on the aforementioned series for drivers and device tree bindings.
