> 2.3.x
> 
> Align RDNA2.x with other asics.  One HDP bit per SDMA instance,
> aligned with firmware.  This is effectively a revert of
> commit 369b7d04baf3 ("drm/amdgpu/nbio2.3: don't use GPU_HDP_FLUSH bit
> 12").
> On further discussions with the relevant hardware teams,
> re-align the bits for SDMA.
