Merged back in Linux 7.1 was the Yogafan driver to support fan speed monitoring across more Lenovo Yoga, Legion, Flex, Slim and IdeaPad laptop models. That Yogafan driver is being extended further in Linux 7.3 to support several additional Lenovo laptop models.
The newly-added device support set to arrive for Linux 7.3 includes the IdeaPad 3 15ALC6, Legion Pro 7 16, Yoga Pro 7 14IAH, Yoga 7 16ARP8 and also the XiaoXinPro 13ARE.
This patch amounting to 69 more lines of C code adds in the proper DMI entries for these additional laptop models for working fan speed reporting. That patch is queued in the hardware monitoring subsystem's "hwmon-next" Git branch ahead of the Linux 7.3 merge window.
