Partial dmesg is at: https://github.com/pavelmachek/missy/blob/master/db/phone/nokia/n900/pavel/2018.1291171648263/dmesg.out I should be able to get full one... I did git bisect, and the winner seems to be: pavel@duo:/data/l/linux-n900$ git bisect bad c85823390215e52d68d3826df92a447ed31e5c80 is the first bad commit commit c85823390215e52d68d3826df92a447ed31e5c80 Author: Linus Walleij <linus.wall...@linaro.org> Date: Wed Dec 27 16:37:44 2017 +0100 gpio: of: Support SPI nonstandard GPIO properties Before it was clearly established that all GPIO properties in the device tree shall be named "foo-gpios" (with the deprecated variant "foo-gpio" for single lines) we unfortunately merged a few bindings which named the lines "gpio-foo" instead. This is most prominent in the GPIO SPI driver in Linux which names the lines "gpio-sck", "gpio-mosi" and "gpio-miso". As we want to switch the GPIO SPI driver to using descriptors, we need devm_gpiod_get() to return something reasonable when looking up these in the device tree. Put in a special #ifdef:ed kludge to do this special lookup only for the SPI case and gets compiled out if we're not enabling SPI. If we have more oddly defined legacy GPIOs like this, they can be handled in a similar manner.
