The chip follows the LM63 register model and can provide a thermal cooling device when #cooling-cells is present. Do not provide a national,lm63 fallback because the CTF2301 is not fully compatible with LM63. It uses different conversion-rate encodings, extended local-temperature registers, additional fan lookup table entries, and device-specific PWM and ALERT/TACH configuration. An older LM63 driver would therefore not operate the device correctly.
