[PATCH v2 1/3] ALSA: hda/tas2781: Modification for add tas2781 driver for SPI
From: Baojun Xu
Date: Mon Apr 08 2024 - 22:49:44 EST
Integrate tas2781 configs for HP Laptops. Every tas2781 in the laptop
will work as a single speaker on SPI bus. The code support realtek as
the primary codec.

- Change depends on SPI to SPI_MASTER in sound/pci/hda/Kconfig
- Add select SND_HDA_SCODEC_COMPONENT in sound/pci/hda/Kconfig
- Change comp_generic_fixup() 5th parameter from "-%s:00" to
"-%s:00-tas2781-hda.%d" in sound/pci/hda/patch_realtek.c
- Change chain_id from ALC285_FIXUP_THINKPAD_HEADSET_JACK to
ALC285_FIXUP_HP_GPIO_LED in sound/pci/hda/patch_realtek.c
- Remove project name "Gemtree"
