2023-09-11ASoC: cs35l45: Add AMP Enable Switch controlVlad Karpovich1-1/+6
The "AMP Enable Switch" is useful in systems with multiple amplifiers connected to the same audio bus but not all of them are needed for all use cases.

Link VMON, IMON, TEMPMON, VDD_BSTMON and VDD_BATTMON to DSP1. The CSPL firmware uses them for the speaker calibration and monitoring.

2023-09-11ASoC: cs35l45: Analog PCM Volume and Amplifier Mode controlsVlad Karpovich1-0/+148
Adds "Analog PCM Volume" control with supported values 0 = 10dB,1 = 13dB,2 = 16dB and 3 = 19dB. The amplifier can operate either in Speaker Mode or Receiver Mode as configured by the user. Speaker Mode has four gain options to support maximum amplifier output amplitude for loud speaker application. Receiver Mode has further optimized noise performance while maintaining sufficient output to support phone receiver application. While configured in Receiver Mode, the analog PCM Volume control is disabled and the analog gain is fixed to 1dB.

2023-03-21ASoC: cs35l45: Hibernation supportVlad.Karpovich1-0/+80
Adds support for a low-power Hibernation State. Add support for a low-power hibernation state for the DSP. In this state the DSP RAM contents are maintained, such that firmware does not need to be re-downloaded, but the rest of the chip's register state is lost. Entry to this state is achieved via the register interface (either by an external driver using the control port, or the programmable DSP). Exit from this state is triggered by activity on device GPIO pins, intended SPI transaction, or I2C transaction with intended slave address.

2022-06-14ASoC: cs35l45: Add endianness flag in snd_soc_component_driverCharles Keepax1-0/+2
The endianness flag is used on the CODEC side to specify an ambivalence to endian, typically because it is lost over the hardware link. This device receives audio over an I2S DAI and as such should have endianness applied.

2022-06-06ASoC: cs35l45: Make cs35l45_remove() return voidUwe Kleine-König1-3/+1
cs35l45_remove() always returns zero. Make it return no value which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c driver remove callbacks is ignored anyway. This prepares making i2c remove callbacks return void, too.
