[PATCH 3/3] dt-bindings: display/msm/gpu: constrain reg/reg-names per variant

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



MMIO address space is known per each variant of Adreno GPU, so we can
constrain the reg/reg-names entries for each variant.  There is no DTS
for A619, so that part is not accurate but could be corrected later.
