[PATCH v4 6/7] drm/msm/dpu: stop using raw IRQ indices in the kernel traces

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

 



In preparation to reworking IRQ indcies, stop using raw indices in
kernel traces. Instead use a pair of register index and bit. This
corresponds closer to the values in HW catalog.
