Not much. S6E63M0 uses "spi" as it is right now and is not using
the existing DBI code.

So it would require it to start using the DBI core to begin with.
If it can. Which is kind of an orthogonal task.

What would be the defining character for it to
be "DBI"? I do see that the driver sends MIPI standard commands
over SPI. I suspect this is another standard without public specs...

This approach is based on the approach from IIO, se e.g.:
drivers/iio/accel/bmc150-accel-core.c
drivers/iio/accel/bmc150-accel.h
drivers/iio/accel/bmc150-accel-i2c.c
drivers/iio/accel/bmc150-accel-spi.c

I'm happy to rework it any direction. If the other patch set is going to
take time to finalize (as in: will not merge it the coming week, need to
hack and stuff) then I'd prefer to apply this so I know my display works
in v5.10. I can certainly rework it into Paul's framework when that
arrives.

Yours,
