This includes Maxim MAX86900 heart rate sensor and oximeter, which seems to be similar to other health sensors by Maxim, but it is not fully compatible; STM32F401 MCU which acts like a sensor hub, which can be flashed and controlled via the SPI bus, for which I made some simple firmware to check if it's possible to program with custom code, and it appears you can do so, but at the moment kernel lacks the APIs to either control sensors directly through the MCU or any standards for a sensor hub, so it's laid off; WM5110 audio codec which fails to communicate for some reason.

the bug occurs randomly regardless of any variables, but it seems to occur less if the Exynos DRM kernel module is loaded later in the kernel boot process (the bug concludes in display filling with static) ; another issue is that efforts to support the S6E3FA2 panel are still going on, and the driver for the panel is not in the kernel tree yet.
