ASoC: ak4458: Add support for AK4497
AK4497 is a 32-bit 2ch DAC and has the same register map as AK4458 with few exceptions: * AK4497 has one more register at the end of register space DFS_READ which is a read only register that allows users to read FS Auto Detection mode. We currently do not use this register so we use the same regmap structure as for ak4458. * Because AK4458 is an 8ch DAC there are some fields that are only used by AK4458 and marked as reserved for AK4497, so for this reason we need to have a distinct set of controls, widgets and routes. Datasheet for AK4497 is at: https://www.akm.com/akm/en/file/ev-board-manual/AK4497EQ.pdf Datasheet for AK4458 is at: https://www.akm.com/akm/en/file/datasheet/AK4458VN.pdf Signed-off-by: Daniel Baluta <daniel.baluta@nxp.com> Signed-off-by: Mark Brown <broonie@kernel.org>
