I noticed a couple differences between this and what we are using...
Yours:
+ ldo8-in-supply = <&tps65090_dcdc3_reg>;
+ ldo9-in-supply = <&palmas_smps9_reg>;
Ours:
ldo8-in-supply = <&tps65090_dcdc2_reg>;
ldo9-in-supply = <&tps65090_dcdc2_reg>;
We also specify supplies (floating) for smps6 and smps10. I don't think
that matters though.
Also we have the vmmc-supply and sd-slot-supply propeties set for the sd
card slot, like so:
vmmc-supply = <&palmas_smps3_reg>;
sd-slot-supply = <&palmas_smps9_reg>;
Also, we have the interrupt trigger mode different for the palmas:
Yours:
+ interrupts = <0 86 0x4>;
Ours:
interrupts = <0 86 0x8>;
I think other than that they should be the same.
