Cleanups for the dmaengine code build on top of current fixes.
2022-05-03ASoC: rt5514: Fix event generation for "DSP Voice Wake Up" controlMark Brown1-1/+1
The driver has a custom put function for "DSP Voice Wake Up" which does not generate event notifications on change, instead returning 0. Since we already exit early in the case that there is no change this can be fixed by unconditionally returning 1 at the end of the function.

2022-04-06ASoC: rt*: use simple i2c probe functionStephen Kitt1-3/+2
The i2c probe functions here don't use the id information provided in their second argument, so the single-parameter i2c probe function ("probe_new") can be used instead. This avoids scanning the identifier tables during probes.

Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write.

2017-04-14ASoC: rt5514: Unconfuse the rt5514 at probe / resume timeDouglas Anderson1-0/+28
The rt5514 can get confused and incorrectly detect a start bit if the SCL/SDA lines happen to both go low and then high again. This situation has been seen to happen at reboot time and is also theoretically possible during suspend/resume if the rt5514 keeps power but we shut down the i2c connection. When this happens the rt5514 is confused about the state of the i2c bus and won't recognize its own address. That will lead to the rt5514 incorrectly NAKing the first transfer. A single i2c transfer to any address should be enough to get the rt5514 out of this funky state. It is currently believed that this problem should be fixed in the rt5514 driver itself because it seems that the i2c controller in the rt5514 is easily confused. Most i2c devices wouldn't detect a start bit in this case. Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Mark Brown <broonie@kernel.org>

This is the initial codec driver for rt5514. The codec includes a low power DSP for voice wake up. The register address is incremental by 4 in the DSP memory map. In order to recover the codec settings in the codec mode and manipulate the DSP mode for voice wake up, we use the multi-level register map. One is for ALSA API in codec mode that can be recovered by cache before recording. Another is for DSP related settings that can be accessed with 32bit address of the DSP in the application of voice wake up.
