Hi Konrad, That is how Qualcomm refers to the type in the downstream 4.4 and 5.4 kernels. I dont have any other reference to the name unless somebody from Qualcomm can chime in.

APSS PLL type will be used by the IPQ8074 APSS driver for providing the CPU core clocks and enabling CPU Frequency scaling. This is ported from the downstream 5.4 kernel.
