+/**
+ * struct llcc_slice_config - Data associated with the llcc slice
+ * @usecase_id: Unique id for the client's use case
+ * @slice_id: llcc slice id for each client
+ * @max_cap: The maximum capacity of the cache slice provided in KB
+ * @priority: Priority of the client used to select victim line for replacement
+ * @fixed_size: Boolean indicating if the slice has a fixed capacity
+ * @bonus_ways: Bonus ways are additional ways to be used for any slice,
+ *		if client ends up using more than reserved cache ways. Bonus
+ *		ways are allocated only if they are not reserved for some
+ *		other client.
+ * @res_ways: Reserved ways for the cache slice, the reserved ways cannot
+ *		be used by any other client than the one its assigned to.
+ * @cache_mode: Each slice operates as a cache, this controls the mode of the
+ *             slice: normal or TCM(Tightly Coupled Memory)
+ * @probe_target_ways: Determines what ways to probe for access hit. When
+ *                    configured to 1 only bonus and reserved ways are probed.
+ *                    When configured to 0 all ways in llcc are probed.
+ * @dis_cap_alloc: Disable capacity based allocation for a client
+ * @retain_on_pc: If this bit is set and client has maintained active vote
+ *               then the ways assigned to this client are not flushed on power
+ *               collapse.
+ * @activate_on_init: Activate the slice immediately after it is programmed
+ * @write_scid_en: Bit enables write cache support for a given scid.
+ * @write_scid_cacheable_en: Enables write cache cacheable support for a
+ *			     given scid (not supported on v2 or older hardware).
