Move tas2563 from tas2562 driver to tas2781 driver to unbind tas2563 from tas2562 driver code and bind it to tas2781 driver code, because tas2563 only work in bypass-DSP mode with tas2562 driver. In order 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 does is to parse the firmware and download it to the chip, then power on the chip. So, tas2781 driver can be resued as tas2563 driver. Only attention will be paid to downloading corresponding firmware. Signed-off-by: Shenghao Ding <shenghao-ding@ti.com> --- Change in v5: - Add tas2563 to tas2781 driver. - Add more comments on why move tas2563 to tas2781 driver. - Provide rationale in terms of bindings and hardware, not in terms of driver. Or at least not only. - In all cases, to make the lists ordered by a chip model, tas2563 is first, tas2781 is second. --- sound/soc/codecs/tas2781-i2c.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-)
