linux4microchip-2022.04 tag

Kernel

Enhancements are added on top of the official v5.15 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 v5.15.x version is merged in our branch.

Here is a little summary of the main additional enhancements:

  • Integration of stable kernel updates up to v5.15.32
  • Addition of the new SAMA7G54 SoC as part of the SAMA7G5 family
  • WILC: Update driver & firmware to 15.7 with WPA3 security support
  • Add support for Sony imx274 camera sensor
  • ISC driver moved to media controller paradigm for image acquisition pipeline (MIPI CSI-2)
  • Support for External Interrupt Controller (EIC) available on SAMA7G5
  • Add Dinamic and Voltage Scaling (DVFS) support with Operating Performance Points (OPP) for 90MHz, 250MHz, 600MHz, 800MHz, 1GHz frequencies for SAMA7G5
  • Refactored clocks' suspend/resume
  • Support for power management modes: WFI (standby), ULP0, ULP1, BSR for SAMA7G5
  • Low power mode for on board crystal oscillators in ULP0 and ULP1 to reduce overall power consumption
  • GEMAC support with RGMII and MII for SAMA7G5
  • Fix GEMAC Wake On LAN on ulp0, ulp1 for SAMA7G5
  • Increased PIT64B clockevent timer frequency to 5MHz for better timers resolution on
  • CPU Idle support with minimized CPU frequency and DDRAM in self-refresh for SAMA7G5 family
  • Use ADC reworked driver from mainline
  • ADC support for reading temperature channel available on SAMA7G5
  • Support for accessing memory backed by OTP controller (modeled as NVMEM driver) for SAMA7G5
  • Thermal management support for SAMA7G5
  • Add QSPI / Octal SPI driver for SAMA7G5 (Single, Dual, Quad, Octal DTR modes), tested with mx66lm1g45g
  • Add NAND support for SAMA7G5 and test it with 29F4G08ABAEA
  • Add support for mx66lm1g45g NOR Flash, implement byte swap to fix endianness in 8D-8D-8D(Octal DTR)
  • Enable crypto engines on SAMA7G5: AES, TDES, SHA with same features as on sama5d2 SoC
  • Cleanup and runtime PM support for atmel-rng driver
  • Fix deadlocks on AT91 DMA driver
  • Reset controller support for USB PHY on SAMA7G5
  • Improve USB PHY clock handling when used by both Host and Device for SAMA7G5
  • Add SAMA7G5 audio interfaces drivers: SPDIF-TX, SPDIF-RX, I2S, SCC
  • Add Asynchronous Sample Rate Converter (ASRC) audio driver for SAMA7G5
  • Implement microphone PDMC driver using DMA mode for SAMA7G5
  • Enable CAN driver for SAMA7G5
