Why does this mean you need multiple regulators?  A single regulator can
of course supply multiple devices.

I got your point but tps65910 driver is failing if we add single fixed
regulator. Solution is driver needs to change or add multiple fixed
regulators.

No, really.  One regulator can supply many things, not being a.

So you've specified a whole bunch of supplies and this one individual
supply is not matching (and it's not the first...).  You should
investigate what's gone wrong there rather than bodging around the
problem.  I can't immediately say anything much based on the information
you've given.

Sorry for the noise in this issue, I found the root cause. I
was defining the supply names like this which is wrong.

&tps {
        regulators {
                vcc1-supply = <&vcc5v_supply>;
                vcc2-supply = <&vcc5v_supply>;
                vcc3-supply = <&vcc5v_supply>;
                vcc4-supply = <&vcc5v_supply>;
                vcc5-supply = <&vcc5v_supply>;
                vcc6-supply = <&vcc5v_supply>;
                vcc7-supply = <&vcc5v_supply>;
                vccio-supply = <&vcc5v_supply>;

                vrtc_reg: regulator at 0 { /* vrtc input is vcc7 */
                        regulator-always-on;
                };

                ... 
                ...
        };
};

This was suppose to be

&tps {
        vcc1-supply = <&vcc5v_supply>;
        vcc2-supply = <&vcc5v_supply>;
        vcc3-supply = <&vcc5v_supply>;
        vcc4-supply = <&vcc5v_supply>;
        vcc5-supply = <&vcc5v_supply>;
        vcc6-supply = <&vcc5v_supply>;
        vcc7-supply = <&vcc5v_supply>;
        vccio-supply = <&vcc5v_supply>;

        regulators {

                vrtc_reg: regulator at 0 { /* vrtc input is vcc7 */
                        regulator-always-on;
                };

                ... 
                ...
        };
};

Thanks for your continuous feedback.

Thanks
