* atomically.
* We use GSL for this:
* - immediate flip: find first available GSL group if not already assigned
*                   program gsl with that group, set current OTG as master
*                   and always us 0x4 = AND of flip_ready from all pipes
* - vsync flip: disable GSL if used
*
* Groups in stream_res are stored as +1 from HW registers, i.e.
* gsl_0 <=> pipe_ctx->stream_res.gsl_group == 1
* Using a magic value like -1 would require tracking all inits/resets
