Subject: [PATCH] dmaengine: idxd: Add a new IAA device ID on Panther Lake family platforms

A new IAA device ID, 0xb02d, is introduced across all Panther Lake family
platforms. Add the device ID to the IDXD driver.

Hi, Vinod,

This patch is applied cleanly on the next branch in the dmaengine repo.

The next branch already includes a few new DSA/IAA device IDs in IDXD
driver.

Please check the patches and the reasons why the new IDs should be added:
