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.
