17 This driver allows to read temperature inside Samsung Exynos4/5 series of SoC.
19 The chip only exposes the measured 8-bit temperature code value
21 Temperature can be taken from the temperature code.
22 There are three equations converting from temperature to temperature code.
27 Tc = (T - 25) * (TI2 - TI1) / (85 - 25) + TI1
31 Tc = T + TI1 - 25
