Generic comment: as you are reworking speed bins implementaiton, could
you please take a broader look. A5xx just reads nvmem manually. A6xx
uses adreno_read_speedbin(). And then we call adreno_read_speedbin
second time from from adreno_gpu_init(). Can we get to the point where
the function is called only once for all the platforms which implements
speed binning?
