Which works mostly fine except of the cache initialisation. If I use num_reg_defaults_raw with REGCACHE_MAPLE as proposed by Andy Shevchenko, first access to regmap values over debugfs will explode with NULL pointer etc...Yeah, this is known issue in regcache core. I don't remember how it was worked around in pinctrl-cy8c95x0.c.
That said, have you run the v6.19-rcX kernels? It should have some patches related to the regcache, but I need to test and send the actual fix for that NULL case.

If I remove num_reg_defaults_raw, I need to read register manually to init defaul values as implemented in v3.
