First six of the backport address numerous problems troubling HDAudio configuration users for Skylake driver. Upstream series: "ASoC: Intel: Skylake: Fix HDaudio and Dmic" [1] provides the explanation and reasoning behind it. These have been initialy pushed into v5.7-rc1 via: "sound updates for 5.7-rc1" [2] by Takashi.
Last two patches are from: "Add support for different DMIC configurations" [3] which focuses on HDAudio with DMIC configuration. Patch: "ASoC: Intel: Skylake: Add alternative topology binary name" of the mentioned series has already been merged to v5.4.y -stable and thus it's not included here. Fixes target mainly Skylake and Kabylake based platforms, released in 2015-2016 period.
