On the Renesas RZ/G3S SMARC Carrier II board having a DA7212 codec (using da7213 driver) connected to one SSIF-2 available on the Renesas RZ/G3S SoC it has been discovered that using the runtime PM API for suspend/resume (as will be proposed in the following commits) leads to the codec not being propertly initialized after resume. This is because w/o max_register populated to regmap_config the regcache_rbtree_sync() breaks on base_reg > max condition and the regcache_sync_block() call is skipped.
