It's a nice bonus but surely not urgent or necessary.

H I think we should probably update omap1_defconfig to enable
all the OMAP1 drivers so we have

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
Hi,
This does not compile as nokia770_ads7846_props is declared twice,
and nokia770_cbus_props and nokia770_mpuio_gpiochip_swnode are missing.

The Nokia 770 is using GPIOs from the global numberspace on the
CBUS node to pass down to the LCD controller. This regresses when we
let the OMAP GPIO driver use dynamic GPIO base.
The Nokia 770 now has dynamic allocation of IRQ numbers, so this
needs to be fixed for it to work.
As this is the
