linux4microchip-2025.04 tag

Kernel

Enhancements are added on top of the official v6.12 Linux kernel tag where most of the Microchip SoC features are already supported. Note as well that we re-integrate each and every stable kernel release on top of this Long Term Support (LTS) kernel revision. This means that each v6.12.x version is merged in our branch.

Here is a little summary of the main additional enhancements:

  • Integration of stable Long Term Support (LTS) kernel updates up to v6.12.22
  • Improve support for SAMA7G65 Curiosity board.
  • Add initial support for SAMA7G54 SoM and SAM9x75 SoM
  • Add support for unified WILC S02 FW 3.1 and WILC 1000/3000 FW 16.4 WiFi / BLE driver.
  • Add initial support for GFX2D GPU
  • Add support for ASRC peripheral to peripheral for SAMA7G65
  • Enable WM8731 audio codec as a module.
  • Add shutdown controller support for SAM9X7 SoC.
  • Improve SoC driver with support for SAMA7D65.
  • Crypto: add fallback for unsupported ESP header length (not multiple of 4 words).
  • Clock: configure ACR register in all PLL settings. Update clock API usage for SAMA7G5 and SAMA7D65.
  • OP-TEE: Update SCMI for SAMA7G5 to include GCLK for PDMC0 and PDMC1.
  • QSPI: add support for SAMA7D65
  • Added support for PAC194X and PAC195X Current and Power Monitors
  • Added support for LAN9646 and updated support for LAN937X, KSZ9896, KSZ9477 gigabit Ethernet switches
