Looks like the problem occurs because commit 922a9f936e40 ("regmap: mmio: Convert to regmap_bus and fix accessor usage") has removed ->read callback from MMIO regmap implementation but it is used (via regmap_raw_read()) by regcache code to initialize cache if reg default values weren't provided explicitly. If I revert this commit the SSI probes successfully again. Looks like a possible solution would be to change regmap_raw_read() to do read using _regmap_read in case the cache is bypassed and there is no ->read callback defined for regmap implementation.
