People don't talk of "Upstreaming" and "Qualcomm chipsets" in the same sentence. Even if they do, it is mostly to point out millions of lines of out of tree code in downstream kernel!

Only constant thing in nature is the change it brings in, similarly we have changes in the status of the Qualcomm chipsets upstream. There has been a lot of work done by Linaro and Qualcomm Innovation Center to ensure a better story for Qualcomm chipsets upstream.

This talk shares the story of upstreaming of baseport for one of the latest generation premier tier SoC SM8150 aka Snapdragon SDM855

The SM8150 support was added to mainline kernel in v5.4, this talk focuses on how the drivers were ported from downstream tree released on codeaurora.org.

This talk shares the experience gained while porting, upstreaming and the tips and tricks learned. This will help other developers who are struggling to get upstream working on the Qualcomm devices.
