[PATCH 0/2] drm/msm/a6xx: use correct timestamp counter on A750 GPU

[Neil Armstrong]

The A750 uses a different counter register as used on the downstream
driver:

static u64 gen7_9_0_read_alwayson(struct adreno_device *adreno_dev)
{
...
	/* Always use the GMU AO counter when doing a AHB read */
	gmu_core_regread(device, GEN7_GMU_CX_AO_COUNTER_HI, &hi);
	gmu_core_regread(device, GEN7_GMU_CX_AO_COUNTER_LO, &lo);
...
}

gen7_reg.h:#define GEN7_GMU_CX_AO_COUNTER_LO		0x1f880
gen7_reg.h:#define GEN7_GMU_CX_AO_COUNTER_HI		0x1f881
