Linux 5.18 has been released a bit over a week ago. As usual, we recommend the resources provided by LWN.net (part 1 and part 2) and KernelNewbies.org to get an overall view of the major features and improvements of this Linux kernel release.
Bootlin engineers have collectively contributed 80 patches to this Linux kernel release, making us the 28th contributing company according to these statistics.
- Alexandre Belloni, as the RTC subsystem maintainer, continued to improve the overall subsystem, and migrate drivers to new features and mechanisms introduced in the core RTC subsystem
- Clément Léger contributed a new RTC driver that allows to use the RTC exposed by the OP-TEE Trusted Execution Environment, as well as a few other fixes
- Hervé Codina and Luca Ceresoli contributed some fixes: Hervé to the dw-edma dmaengine driver, and Luca to the Rockchip RK3308 pinctrl driver
- Miquèl Raynal, as the MTD subsystem co-maintainer, contributed the remainder of his work to generalize the support of ECC handling, and allow both parallel and SPI NAND to use either software ECC, on-die ECC, or ECC done by a dedicated controller. Included in this work is a new driver for the Macronix external ECC engine, in drivers/mtd/nand/ecc-mxic.c
- Miquèl Raynal also made a few contributions to the 802.15.4 part of the networking stack, and we have more contributions in this area coming up.
- Paul Kocialkowski contributed a small fix to Allwinner Device Tree files, and another attempt at fixing an issue with the display panel detection/probing in the DRM subsystem
