In only RCA binary loading case, only default dsp program will be work inside the chip.

--- v1: - Split out the different logical changes into different patches. - rename tasdevice_dsp_fw_state -> tasdevice_fw_state, the fw are not only dsp fw, but also RCA(Reconfigurable data, such as acoustic data and register setting, etc). - Add TASDEVICE_RCA_FW_OK in tasdevice_fw_state to identify the state that only RCA binary file has been download successfully, but dsp fw is not loaded or loading failure. - Add the this strategy into tasdevice_tuning_switch. - If one side of the if/else has a braces both should in tasdevice_tuning_switch. - Identify whehter both RCA and DSP have been loaded or only RCA has been loaded in tasdevice_fw_ready. - Add check fw load status in tasdevice_startup. - remove ret in tasdevice_startup to make th code neater. --- include/sound/tas2781-dsp.h | 3 ++- sound/soc/codecs/tas2781-fmwlib.c | 14 ++++++++++---- sound/soc/codecs/tas2781-i2c.c | 30 ++++++++++++++++++------------ 3 files changed, 30 insertions(+), 17 deletions(-)
