+ * @partition: Resolved partition
+ *
+ * In a partitioned system a CPU package has two separate MMIO ranges (Under
+ * two PCI devices). But the CPU package compute die/power domain IDs are
+ * unique in a package. User space can get compute die/power domain ID from
+ * CPUID and MSR 0x54 for a CPU. So, those IDs need to be preserved even if
+ * they are present in two different partitions with its own order.
+ *
+ * For example for command ISST_IF_COUNT_TPMI_INSTANCES, the valid_mask
+ * is 111111b for a 4 compute and 2 IO dies system. This is presented as
+ * provided by the hardware in a non-partitioned system with the following
+ * order:
+ * I1-I0-C3-C2-C1-C0
+ * Here: "C": for compute and "I" for IO die.
+ * Compute dies are always present first in TPMI instances, as they have
+ * to map to the real power domain/die ID of a system. In a non-partitioned
+ * system there is no way to identify compute and IO die boundaries from
+ * this driver without reading each CPU's mapping.
+ *
+ * The same order needs to be preserved, even if those compute dies are
+ * distributed among multiple partitions. For example:
+ * Partition 1 can contain: I1-C1-C0
+ * Partition 2 can contain: I2-C3-C2
+ *
+ * This will require a conversion of user space IDs to the actual index into
+ * array of stored power domains for each partition. For the above example
+ * this function will return partition and index as follows:
+ *
+ * ============= ========= ===== ========
+ * User space ID Partition Index Die type
+ * ============= ========= ===== ========
+ * 0 0 0 Compute
+ * 1 0 1 Compute
+ * 2 1 0 Compute
