Well, I just did 'git grep regmap_i2c drivers' and 'git grep regmap_spi drivers/' and found eg. drivers/iio/pressure/zpa2326_i2c.c drivers/iio/pressure/zpa2326_spi.c There's plenty of drivers using regmap in drivers/ to demonstrate how to use it. And there's always include/linux/regmap.h . In this specific (DSA) case, register either regmap_spi or regmap_i2c in the ksz_switch_register(), pop the regmap pointer into ksz_device and then use it in ksz_read*()/ksz_write*(). You can then, in a subsequent patch, massage the regmap accesses directly into the code instead and drop the ksz_read*()/ksz_write*() functions altogether, since those would be just regmap function wrappers. And if you're still lost, I can start on the conversion myself. I'm sure Sergio can wait. -- Best regards, Marek Vasut
