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@ti.com/ 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
