linux4sam_6.1 tag

Kernel

Enhancements are added on top of the official v4.19 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 v4.19.x version is merged in our branch.

Here is a little summary of the main additional enhancements:

• Integration of stable kernel updates up to v4.19.56
• Redesign of the Image Sensor Controller (ISC) driver with new White balance enhanced features.
• Driver for the WILC3000 and WILC1000 release 15.2 in place in the Linux4SAM kernel and ready to use
• TWI hardware filters support that filter out possible glitches on the TWI wires for both SAMA5D4 Xplained and SAMA5D2 Xplained
• Add 9bit/Multidrop support in USART driver
• PIOBU pin controller driver
• MCP16502 PMIC driver
• ACT8945A: PM support (integrated in mainline)
• Ethernet: add runtime PM support (integrated in mainline)
• Ethernet: add backup and self-refresh support (integrated in mainline)
• Ethernet: use of NAPI GRO helpers to improve RX performance
• QSPI: move driver under the SPI-MEM interface. The controller can be used with NAND or NOR flashes.
• Support for Omnivision ov5640 now available for both SAMA5D2 Xplained and SAMA5D27 SOM1 EK
