Linux 5.10, Bootlin contributions

Linux 5.10 was released a few weeks ago, and while 5.11-rc2 is already out, it’s still time to look at what Bootlin contributed to the 5.10 kernel. As usual, for a broad overview of the major changes in 5.10, we recommend reading the LWN articles: 5.10 merge window part 1, the rest of the 5.10 merge window, or the 5.10 KernelNewbies page.

Overall, Bootlin contributed 78 patches to this kernel release, in the following areas:

  • Alexandre Belloni did a number of improvements in the support of Microchip ARM platforms: device tree updates, code cleanups, etc.
  • Alexandre Belloni added a new rv3032 RTC driver and did some improvements to the r9701 RTC driver.
  • Miquèl Raynal implemented a significant rework of how ECC engines are handled in the MTD subsystems, so that ECC engines can be used not just for parallel NANDs but also for SPI NANDs. See also the talk that Miquèl gave at the Embedded Linux Conference Europe on this topic: slides and video.
  • Miquèl Raynal contributed a few improvements to the tlv320aic32x4 audio codec driver.
  • Paul Kocialkowski made some small improvements, one in the OV5640 camera sensor driver, and one in the Rockchip DRM driver.
  • Thomas Petazzoni implemented a performance improvement in the max310x driver, used for SPI-connected UART controllers.

In addition to these code contributions, we also contribute by having several of our engineers be maintainers of a few subsystems of the Linux kernel. As part of this:

  • Miquèl Raynal reviewed and merged 47 patches touching the MTD subsystem he co-maintains with other kernel developers.
  • Alexandre Belloni reviewed and merged 42 patches touching either the Microchip ARM or MIPS platforms, or the RTC subsystem.
  • Grégory Clement reviewed and merged 2 patches touching the Marvell ARM/ARM64 platform support.

Here is the complete list of our commits to 5.10.
