Agreed, my downstream source for this device also uses
MSM_BUS_MASTER_GRAPHICS_3D=26 with mas_rpm_id=ICBID_MASTER_GFX3D=6, and
on the right-side MSM_BUS_SLAVE_EBI_CH0=512 which resolves to
slv_rpm_id=ICBID_SLAVE_EBI1=0. Both on &bimc.
Have you double-checked all the other interconnect paths in this file?
