Create tas2563 side codec HDA driver for Lenovo Yoga 7 14ARB7 laptops. It has two smart amplifiers that can load firmware (tuning file) and calibration data. The calibration data can be read from EFI variables. All of the tas2563s in the laptop will be aggregated as one audio speaker. The code supports realtek codec as the primary codec.
