This STC8 microcontroller is used on a range of Hasivo managed switches. It typically performs some fan/thermal control, and also has some discrete IO hanging off of it. The fan/thermal control is still somewhat unknown at this stage, but the LED / gpio control has been determined as being two I2C registers which need to be written to with a 'typical' Hasivo 0x40 execute mask set, to change values. Rather than having this expose the LED functionality / thermal control directly, just represent it as an mfd, with some configurable OR'ing of an execute-bit to certain registers (execute-bit-regs). This way different STC8 arrangements can hopefully be handled by devicetree configs rather than needing new driver code.
