2022-06-09Specify clock provider directly to CPU DAIsMark Brown
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: Currently the set_fmt callback always passes clock provider/consumer with respect to the CODEC. This made sense when the framework was directly broken down into platforms and CODECs. However, as things are now broken down into components which can be connected as either the CPU or CODEC side of a DAI link it simplifies things if each side of the link is just told if it is provider or consumer of the clocks. Making this change allows us to remove one of the last parts of the ASoC core that needs to know if a driver is a CODEC driver, where it flips the clock format specifier if a CODEC driver is used on the CPU side of a DAI link, as well as just being conceptually more consistent with componentisation. The basic idea of this patch chain is to change the set_fmt callback from specifying if the CODEC is provider/consumer into directly specifying if the component is provider/consumer. To do this we add some new defines, and then to preserve bisectability, the migration is done by adding a new callback, converting over all existing CPU side drivers, converting the core, and then finally reverting back to the old callback. Converting the platform drivers makes sense as the existing defines are from the perspective of the CODEC and there are more CODEC drivers than platform drivers. Obviously a fair amount of this patch chain I was only able to build test, so any testing that can be done would be greatly appreciated.

2022-06-06ASoC: fsl: Rename set_fmt_new back to set_fmtCharles Keepax
Now the core has been migrated across to the new direct clock specification we can move the drivers back to the normal set_fmt callback.

2019-10-07ASoC: fsl_mqs: Fix error handling in probeDan Carpenter
There are several problems in the error handling in fsl_mqs_probe(). 1) "ret" isn't initialized on some paths. GCC has a feature which warns about uninitialized variables but the code initializes "ret" to zero at the start of the function so the checking is turned off. 2) "gpr_np" is a pointer so initializing it to zero is confusing and generates a Sparse warning. 3) of_parse_phandle() doesn't return error pointers on error, it returns NULL. 4) If devm_snd_soc_register_component() fails then the function should free the "gpr_np".

2019-10-01ASoC: fsl_mqs: Add MQS component driverShengjiu Wang
MQS (medium quality sound), is used to generate medium quality audio via a standard digital output pin. It can be used to connect stereo speakers or headphones simply via power amplifier stages without an additional DAC chip. It only accepts 2-channel, LSB-valid 16bit, MSB shift-out first, frame sync asserting with the first bit of the frame, data shifted with the posedge of bit clock, 44.1 kHz or 48 kHz signals from SAI1 in left justified format; and it provides the SNR target as no more than 20dB for the signals below 10 kHz. The signals above 10 kHz will have worse THD+N values. MQS provides only simple audio reproduction. No internal pop, click or distortion artifact reduction methods are provided. The MQS receives the audio data from the SAI1 Tx section.
