Hi,

Not sure what this comment means. CBUS is for Retu/Tahvo, and touchscreen
is SPI.

When tested w/gpio-descriptors-omap branch, the touchscreen probe fails:

[    2.378540] SPI driver ads7846 has no spi_device_id for ti,tsc2046
[    2.391906] SPI driver ads7846 has no spi_device_id for ti,ads7843
[    2.405029] SPI driver ads7846 has no spi_device_id for ti,ads7845
[    2.418151] SPI driver ads7846 has no spi_device_id for ti,ads7873
[    2.432556] ads7846 spi2.0: Unknown device model
[    2.443817] ads7846: probe of spi2.0 failed with error -22

I don't know if that's caused by any the patches in the branch or some
other regression. With v6.2 it probes OK.
