I tried applying the patch series on 6.6-rc1 and it did not apply cleanly, some patches I needed to manually apply and correct. With all this, it failed compilation at some spi/spi-bcm2835 driver. I disabled that and was able to compile. I thought I should let you know this part. Now, I tried to test the hte and it seems to fail finding the gpio device, roughly around this place [1]. I thought it would be your patch series so tried to just use 6.6rc1 without your patches and it still failed at the same place. I have to trace back now from which kernel version it broke. > > Bart
