There are multiple ways of doing that, e.g. you could export a function

the regmap from syscon into your high-level driver again.

Hi Arnd/Linus,

Thankyou for your comments,
I did try using the full sysconf names in compatible and make use of
syscon driver, with this change the nodes look much neater.

The nodes changes to:

syscfg_sbc:syscfg at fe600000{
    compatible      = "st,stih416-sbc-syscfg", "syscon";
    reg             = <0xfe600000 0x1000>;
};

From:
syscfg_sbc:syscfg at fe600000{
         compatible      = "st,stih416-syscfg";
         reg             = <0xfe600000 0x1000>;
         syscfg-range    = <0 999>;
         syscfg-name     = "SYSCFG_SBC";
};


Also I got rid of the drivers/mfd/stixxxx-syscfg.c driver all together
for this basic support patch series, I will add this once there are new
high level functions.
Additional compatible string will allow code to get to regmap via syscon
apis.

I will get rid of this driver in next version for this series.

Thanks,
srini
