+ * Each of the CPU clusters (Power and Perf) on msm8996 are

+ * |Alt PLL | |
+ * | +---------------------------+
+ * +---------------+ PLL_EARLY
+ *
+ * The primary PLL is what drives the CPU clk, except for times
+ * when we are reprogramming the PLL itself (for rate changes) when
+ * we temporarily switch to an alternate PLL.
+ *
+ * The primary PLL operates on a single VCO range, between 600MHz
+ * and 3GHz. However the CPUs do support OPPs with frequencies
+ * between 300MHz and 600MHz. In order to support running the CPUs
+ * at those frequencies we end up having to lock the PLL at twice
+ * the rate and drive the CPU clk via the PLL/2 output and SMUX.
+ *
+ * So for frequencies above 600MHz we follow the following path
+ * Primary PLL --> PLL_EARLY --> PMUX(1) --> CPU clk
+ * and for frequencies between 300MHz and 600MHz we follow
+ * Primary PLL --> PLL/2 --> SMUX(1) --> PMUX(0) --> CPU clk
+ *
+ * ACD stands for Adaptive Clock Distribution and is used to
+ * detect voltage droops.

- * On SDM845 the GPU GX domain is *almost* entirely controlled by the GMU
- * running in the CX domain so the CPU doesn't need to know anything about the
- * GX domain EXCEPT....
- *
- * Hardware constraints dictate that the GX be powered down before the CX. If
- * the GMU crashes it could leave the GX on. In order to successfully bring back
- * the device the CPU needs to disable the GX headswitch. There being no sane
- * way to reach in and touch that register from deep inside the GPU driver we
- * need to set up the infrastructure to be able to ensure that the GPU can
- * ensure that the GX is off during this super special case. We do this by
- * defining a GX gdsc with a dummy enable function and a "default" disable
- * function.
- *
- * This allows us to attach with genpd_dev_pm_attach_by_name() in the GPU
- * driver. During power up, nothing will happen from the CPU (and the GMU will
- * power up normally but during power down this will ensure that the GX domain
- * is *really* off - this gives us a semi standard way of doing what we need.
