Added rk808 drivers to my and added basic Kconfig/Makefile entry for mfd driver.

chip-id of my pmic is read:

rk808 rk8090: chip id: 0x8090

looks like regulators are enabled during access from my iodomain driver :) except vccio4/5

rk_iodomain fdc20000.syscon@fdc20000:io-domains.of: DEBUG reg:pmuio1 (00000000404b0450) uV:3300000

vccio 4/5 using regulator with name SWITCH_REG1, maybe this is not registered?

&pmu_io_domains {
    pmuio1-supply = <&vcc3v3_pmu>;
    pmuio2-supply = <&vcc3v3_pmu>;
    vccio1-supply = <&vccio_acodec>;
    vccio3-supply = <&vccio_sd>;
    vccio4-supply = <&vcc_3v3>;
    vccio5-supply = <&vcc_3v3>;
    vccio6-supply = <&vcc_1v8>;
    vccio7-supply = <&vcc_3v3>;
    status = "okay";
};

regards Frank
