Currently in my testing drivers I have used regmap for both the SX1301 and the downstream SX1257.
In my SX1257 driver currently the regmap is backed via SPI with devm_regmap_init_spi, please correct me if I am wrong but if I understand correctly this could be split out to regmap backed by SPI in the case of a direct host connection, and a regmap backed by the SX1301's regmapped strobing register interface, regmap_bus?
Is there a precedent to this I can examine?
