In oder to enable DSP mode for tas2563, it has been moved to tas2781 driver. As to the hardware part, such as register setting and DSP firmware, all these are stored in the binary firmware. What tas2781 drivder dooes is to parse the firmware and download them to the tas2781 or tas2563, then power on tas2781 or tas2563. So, tas2781 driver can be resued as tas2563 driver. Only attention will be paid to downloading corresponding firmware. Signed-off-by: Shenghao Ding --- Change in v3: - Add devicetree list and other list of necessary people and lists to CC - Express Compatibility in the bindings - Add more comments on why move tas2563 to tas2781 driver - Provide rationale in terms of bindings and hardware, not in terms of driver.
