Hey this is great news :)

For the dts binding, sgx binding can be generic as we can put sgx
as a child of ti-sysc. Then we just need the reset driver entry
to power up sgx. And that way we should be able to get the kernel
driver merged too even if it initially just powers and idles the
sgx. Then we can maybe recycle some of the existing PSB_RSGX32
defines in the kernel for adding (slow) 2D acceleration like
drivers/gpu/drm/gma500/accel_2d.c does..

Regards,

Tony
