PCM6240 driver implements a flexible and configurable setting for register and filter coefficients, to one, two or even multiple PCM6240 Family Audio chips. Signed-off-by: Shenghao Ding <shenghao-ding@xxxxxx> --- Change in v3: - All these chips have only a portion of the codec's functionality, such as ADC or DAC, and so on, but their audio performance is far superior to the codec's, and cost is lower than codec, and much easier to program than codec. - Use _MAPLE as cache_type for new devices, it's a more modern design with tradeoffs that work better for most current systems. - Rewrite error checks to return immediately on error in pcmdev_dev_read, pcmdev_dev_write, pcmdev_dev_update_bits, and pcmdev_dev_bulk_write, that way there's less indentation and fewer paths later on. - Add profileid check in pcmdevice_set_profile_id, if invalid, set to max-value or 0. - fixed the return value as -EBUSY in pcmdevice_startup - remove unused chn and chenend in pcmdevice_select_cfg_blk - Be consistent with name, ret, rc, err. - fixed compiling warning on iteration 4 invokes undefined behavior in pcmdev_regbin_ready. - remove unnecessary blank line between "module_i2c_driver(pcmdevice_i2c_driver);" and "static struct i2c_driver pcmdevice_i2c_driver". - Move reset into i2c_probe and remove sw_rst callback. - extract the put_vol and get_vol function as pcmdev_put_volsw and pcmdev_get_volsw to reduce the red - Simplify and rewirte gain_control_add code. - Move gain kcontrol into codec_probe. - Unified ret and rc to ret. - correct of_gpio.h to gpio.h - Add an array pcmdev_ctrl_name to store the gain control name. --- sound/soc/codecs/pcm6240.c | 2039 ++++++++++++++++++++++++++++++++++++ 1 file changed, 2039 insertions(+) create
