This patchset applies on top of everything Vinod and I contributed this week. The fist patch correct a simplifying assumption made earlier. With the IceLake BIOS the existing code is fooled by the presence of a second child device and the namespace walk needs to be filtered. This was not needed on previous generations. The second patch fixes a long-standing misalignment between code and DisCo specification, preventing MIPI DisCo properties from being parsed successfully. The third and fourth patch remove restrictions preventing codec drivers from reading DisCo properties. The fifth patch adds definitions from the SoundWire spec that were missed somehow, but will be very much needed for dynamic bandwidth allocation. The last 3 patches realign the code with the MIPI specification. The existing code exposes properties that don't exist, or exposes them with ambiguous wording. Sticking to the specification helps avoid interpretation issues for integrators, and will make sure the follow-up sysfs support is self-explanatory. Parts of this code was initially written by my Intel colleagues Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah, who are either no longer with Intel or no longer involved in SoundWire development. When relevant, I explictly added a note in commit messages to give them credit for their hard work, but I removed their signed-off-by tags to avoid email bounces and avoid spamming them forever with SoundWire patches.
