Bug Description
[Impact]
On HP platform with a new device TI AMP TAS2781, drivers and firmware need to be backported to OEM kernel for hardware enablement.
[Fix]
For drivers, cherry-pick the following commit from linux mainline:
bb5f86ea50ff ALSA: hda/tas2781: Add tas2781 hda SPI driver
For firmware, cherry-pick the following commits from upstream linux-firmware:
5b2173979a ASoC: tas2781: Add dsp firmware for new projects
68eeb2a5e8 ASoC: tas2781: Add regbin firmware by index for single device
312effe785 ASoC: tas2781: Update dsp firmware for Gemtree project
[Test Plan]
1. Boot up Ubuntu OEM kernel
2. Test if sound works fine
[Where problems could occur]
This backport is for the hardware enablement of the new device, so it has nothing to do with regression.
