Going along with other early Linux kernel driver additions for enabling Panther Lake, the intel-lpss driver in Linux 6.12 has made its device ID additions for supporting Panther Lake H and Panther Lake P processors.

The Intel LPSS driver is for supporting the I2C controllers on Intel SoCs along with other low-power interfaces like SPI and HS-UART. LPSS is short for the Low Power Subsystem. As part of the MFD pull request for Linux 6.12, the Intel LPSS driver has support for the initial batch of Panther Lake processors along with Arrow Lake H. The rest of the Multi-Function Devices (MFD) patches this cycle are relatively straightforward without any really exciting elements.

There are quite a number of new device IDs added to the LPSS driver for both Panther Lake H and Panther Lake P. This goes along with other Panther Lake "PNL" device IDs beginning to appear in the kernel since v6.11.

Expect more Panther Lake support to begin appearing soon for the Linux kernel now that the Intel engineers are through the woods with their Arrow Lake and Lunar Lake efforts. Panther Lake is expected next year on Intel's 18A node and is believed to just be targeting mobile/laptop designs. In any event it's great seeing Intel continuing to get their Linux support lined up early for future hardware. Over on the server side we're also beginning to see more Linux enablement around Diamond Rapids.
