Hi, The series is inspired by the effort to standardize TI's arm64 dtsi files to keep all nodes in 'okay' state and let the board dts files disable not needed peripherals (and not properly configured): https://lore.kernel.org/lkml/20201104224356.18040-1-nm@xxxxxx/ In the unlikely (or likely?) event when the dts misses to disable the McASP node which is not configured we currenly and luckily just manage to not crash as we had fixup code in place for legacy pdata boots. This however prints out a message which does not really help to identify the issue. This series will reduce some of the noise during boot (first patch) then adds the needed changes to handle the variations of 'okay': A - have all required DT properties for audio B - gpiochip is enabled A && !B -> everything is OK for audio, no gpiochip registered A && B -> everything is OK for audio, gpiochip is registered !A && B -> audio is not OK, gpiochip is registered. dev_dbg() for audio and do not register SOC DAI and PCM !A && !B -> audio is not OK, no gpiochip. dev_err() and fail the probe Regards, Peter --- Peter Ujfalusi (4): ASoC: ti: davinci-mcasp: Use platform_get_irq_byname_optional ASoC: ti: davinci-mcasp: Remove legacy dma_request parsing ASoC: ti: davinci-mcasp: Simplify the configuration parameter handling ASoC: ti: davinci-mcasp: Handle missing required DT properties sound/soc/ti/davinci-mcasp.c | 294 ++++++++++++++--------------------- 1 file changed, 119 insertions(+), 175 deletions(-) -- Peter Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
