linux4microchip-2025.10 tag

Enhancements are added on top of the official v6.12 Linux® kernel tag where most of the Microchip System on Chip (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 v6.12.48
  • Add initial support for SAMA7D65 Curiosity Pro board
  • Add WPA3 support for WILC3000, unified WILC S02 device support, FW 16.5 Wi-Fi® / Bluetooth® Low Energy (BLE) driver
  • Add support for Direct Rendering Manager (DRM) atomic operations
  • Enhanced DRM/High-Level Controller Display Controller (HLCDC), Low-Voltage Differential Signaling (LVDS), and Display Serial Interface (DSI) controller support for SAMA7D65 and SAM9X7
  • Fix Universal Asynchronous Receiver/Transmitter (UART) and Serial Peripheral Interface (SPI) FIFO size for SAMA5D2, SAMA7G5 and SAMA7D65
  • Use  CLASSD conservative timings for SAMA5D2, SAM9x60 and SAM9x75
  • Use General Purpose Input/Output (GPIO) to detect SD Card presence instead of polling for SAMA7D65 Curiosity
  • Support for powering off the SD Card on SAMA7D6
  • Add aliases for SDMMC in boards' device trees
  • Implement SDMMC tuning errata for SAMA5D2 and SAMA7D6
  • Add support for pin polarity for GPIOs used as ULP1 wake-up sources
  • Add support for SPI controller to use the optional GCLK as clock source
  • Add I3C driver for SAMA7D65 and LSM6DSx sensor
  • Improve Image Sensor Controller (ISC) driver by exporting histogram statistics to user's pace, add hue and saturation as v4l2 controls, and improve Grey World Auto White Balance (AWB)
  • Implement USB device disconnect PHY workaround
  • Add external REFCLK support in MACB for RMII / RGMII PHYs. Enable RMII support for SAMA7 GMAC
