With shared policies, this only affects the Denver By failing to read any registers, do you just mean that they read as 0? I suspect the issue may be that the EDVD_COREx_VOLT_FREQ registers are just= =20 used to request VF transitions. If no one has requested anything, the regis= ter=20 will be at its reset value, zero. AIUI, in downstream, the driver retrieves the CPU clock rate by measuring i= t=20 instead of calculating it from an NDIV value, hence it would not run into t= his=20 issue. I think the conclusion would be that if the register reads as zero, = we=20 cannot assume any clock rate. Is it possible to tell the cpufreq framework= =20 that we don't know the rate and it should ask us to set the rate to somethi= ng?=20 Or otherwise at probe time do this by ourselves.
