config SND_DESIGNWARE_I2S tristate "Synopsys I2S Device Driver" depends on CLKDEV_LOOKUP select SND_SOC_GENERIC_DMAENGINE_PCM help Say Y or M if you want to add support for I2S driver for Synopsys desigwnware I2S device. The device supports upto maximum of 8 channels each for play and record. config SND_DESIGNWARE_PCM tristate "PCM PIO extension for I2S driver" depends on SND_DESIGNWARE_I2S help Say Y, M or N if you want to add a custom ALSA extension that registers a PCM and uses PIO to transfer data. This functionality is specially suited for I2S devices that don't have DMA support. cgit'>

iio: bmi160: Fix time needed to sleep after command execution
Datasheet specifies typical and maximum execution times for which CMD register is occupied after previous command execution. We took these values as minimum and maximum time for usleep_range() call before making a new command execution. To be sure, that the CMD register is no longer occupied we need to wait *at least* the maximum time specified by datasheet.
