2021-09-16ASoC: atmel: Convert to new style DAI format definitionsMark Brown1-3/+3
Convert the Atmel drivers to use the new style defines for clocking in DAI formats. Signed-off-by: Mark Brown <broonie@kernel.org> Reviewed-by: Codrin Ciubotariu <codrin.ciubotariu@microchip.com> Acked-by: Peter Rosin <peda@axentia.se>

2021-06-21ASoC: atmel-i2s: Fix usage of capture and playback at the same timeCodrin Ciubotariu1-8/+26
For both capture and playback streams to work at the same time, only the needed values from a register need to be updated. Also, clocks should be enabled only when the first stream is started and stopped when there is no running stream.

2020-11-03ASoC: atmel-i2s: do not warn if muxclk is missingCodrin Ciubotariu1-2/+2
Besides the fact that muxclk is optional, muxclk can be set using assigned-clocks, removing the need to set it in driver. The warning is thus unneeded, so we can transform it in a debug print, eventually to just reflect that muxclk was not set by the driver.

2018-07-03ASoC: atmel-i2s: Remove unnecessary audio PLL clock (aclk)Codrin Ciubotariu1-39/+7
The generated clock (gclk) driver is able to set aclk as its parent and change its rate alone, if needed. This means that our driver no longer needs to configure aclk and we can let gclk select and configure its clock source.
