The CTF2301 shares the overall register layout with LM63, but it is not fully compatible. In particular, 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 driver matching the "national,lm63" fallback would therefore not operate the device correctly. I will explain why a fallback compatible is not suitable in the commit message in the next version. - Troy _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
