GS101 is different (but also e850 and autov9 I assume) from the SoCs that are currently handled by the exynos-chipid driver because the chip ID info is part of the OTP registers. GS101 OTP has a clock, an interrupt line, a register space (that contains product and chip ID, TMU data, ASV, etc) and a 32Kbit memory space that can be read/program/locked with specific commands. On GS101 the "ChipID block" is just an abstraction, it's not a physical device. When the power-on sequence progresses, the OTP chipid values are loaded to the OTP registers. Add the GS101 chip ID support. The support is intentionally added in the exynos-chipid driver, and not in a dedicated Exynos OTP driver, because we estimate that there will not be any OTP consumers in the kernel other than the chip ID/SoC interface. The downstream GS101 drivers confirm this supposition.
