Please just add the BCMs for your GPU:
.bcms = (const struct a6xx_bcm[]) {
{ .name = "SH0", .buswidth = 16 },
{ .name = "MC0", .buswidth = 4 },
{
.name = "ACV",
.fixed = true,
.perfmode = BIT(3),
},
{ /* sentinel */ }
};
You can factor it out since it's common across many a6xx GPUs
and &refer to it from the entry for a620
