linux4microchip+sama7d65-2024.10 tag

Kernel

Enhancements are added on top of the official v6.6 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 v6.6.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 v6.6.23
• Add support for SAMA7D65 Curiosity board
• Basic Support
  • Timers:
    • TCB and PIT64
    • PWM and TC PWM supported
  • DMA: for peripherals and memory to memory usage
  • PMC:
    • Marked MCK3 as critical for proper low power mode operation.
    • Adjusted max frequencies and allowed MCK3 and MCK5 to be referenced in DT.
  • PIO:
    • Added support for GPIO wakeup in low power modes.
  • Serial:
    • Support for USART and console.
    • Added debug UART for DEBUG_LL.
  • I2C / SPI / USART (Flexcom):
    • Added support for I2C, SPI, and USART on flexcoms.
    • Add recovery GPIOs for I2C for SAMA7D65 Curiosity board.
  • Button and LED:
    • Added user button support on GPIOs.
    • Added multi-color LED.
• ADC: Cover All Linux-Related Features + Triggers
  • Adapted the ADC driver for SAMA7D65, including support for temperature calibration data and triggers.
• Thermal Supervision Functions
  • Added thermal zones and temperature sensor ADC features.
  • Thermal Support with OTP Data Retrieval: thermal zones, temperature sensor, and calibration support.
• Power Management
  • ULP0 / ULP1 / Backup with Self-Refresh (BSR) Modes.
  • DVFS Support with Maximum CPU Clock (1 GHz) and added configuration for CPU frequency operating points.
• Crypto Engines: TDES, SHA, AES
• SD-Card Support:
  • Added support for SD-Card and MMC / eMMC in basic modes.
  • SDIO Mode Tested with WILC1000 / WILC3000.
• Ethernet Support:
  • Added support for Ethernet GMAC0 and GMAC1.
• Display Sub-System
