Enables the existing pcm512x driver to control the almost compatible TAS5754 and -76 amplifers. Both amplifiers support only an I2C interface and the internal PLL must be always on to provide necessary clocks to the amplifier section. Tested on TAS5756 with support from Andreas Arbesser-Krasser from Texas Instruments <a-krasser@ti.com> Signed-off-by: Joerg Schambacher <joerg.hifiberry@gmail.com> Link: https://lore.kernel.org/r/20230929150722.405415-1-joerg.hifiberry@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>
