linux4microchip-2026.04 tag

Kernel

Enhancements are added on top of the official v6.18 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 v6.18.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 v6.18.17.
• Improve support for SAMA7D65 platform.
• Add initial support for SAM9X75 Curiosity Pro board.
• Enhance Shutdown controller support for SAMA7D65 platform.
• Add switch support for several Ethernet daughter cards.
• Add support of Vivante GC520UL GFX2D GPU for SAM9X60, SAM9X75 and SAMA7D65.
• Add support for New I3C controller and sensors in SAMA7D65.
• Improve Atmel HLCDC DRM driver.
• ISC: Improve color correction and white balance.
• Enhancements in SDMMC.
• Several other trivial fixes.
