- * Each power well control register contains up to 16 (request, status) HW

- * power well requests each source having its own set of control registers:
- * BIOS, DRIVER, KVMR, DEBUG.
+ * HSW - ICL power wells
+ *
+ * Platforms have up to 3 power well control register sets, each set

+ * - main (HSW_PWR_WELL_CTL[1-4])
+ * - AUX (ICL_PWR_WELL_CTL_AUX[1-4])
+ * - DDI (ICL_PWR_WELL_CTL_DDI[1-4])
+ * Each control register set consists of up to 4 registers used by different
+ * sources that can request a power well to be enabled:
+ * - BIOS (HSW_PWR_WELL_CTL1/ICL_PWR_WELL_CTL_AUX1/ICL_PWR_WELL_CTL_DDI1)
+ * - DRIVER (HSW_PWR_WELL_CTL2/ICL_PWR_WELL_CTL_AUX2/ICL_PWR_WELL_CTL_DDI2)
