Subject: [PATCH 22/31] ASoC: da7213: Populate max_register to regmap_config
From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>
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.
Fixes: ef5c2eba2412 ("ASoC: codecs: Add da7213 codec")
