I'm assuming this isn't the case for r0q. It isn't, the device uses fts2ba61y on the spi8 bus - I hosted the DT at https://github.com/ghatt-o/ss_experiments/blob/main/r0q.dts if you want to take a look. > > Did you enable gpi_dma1, qupv3_id_1 before spi8, when testing The driver probes, but it fails to recognize the touchscreen device and ends up erroring, spi-gpio solves this and I did try enabling those. It also works on the S22+ with spi-gpio, so I decided to do the same on r0q= . > that? I don't see any obvious errors in the dt that would cause > problems > > Konrad
