That is what kernelci.org is for, but we should try to understand how
these platforms broke and have testcases.

Yes. I don't know that the shared flag is a good idea, but we can
discuss that later.

I've looked at some of the failures. Armada 370 looks normal AFAICT,
but the network device evidently does not probe. i.MX6 has no log, but
IIRC it is what failed previously on Grant's last attempt. For OMAP4,
I found the overlapping region here:
omap4_padconf_core: scm@100000 {
compatible = "ti,omap4-scm-padconf-core",
"simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 0x100000 0x1000>;
omap4_pmx_core: pinmux@40 {
compatible = "ti,omap4-padconf",
"pinctrl-single";
reg = <0x40 0x0196>;
#address-cells = <1>;
#size-cells = <0>;
#interrupt-cells = <1>;
interrupt-controller;
pinctrl-single,register-width = <16>;
pinctrl-single,function-mask = <0x7fff>;
};
omap4_padconf_global: omap4_padconf_global@5a0 {
compatible = "syscon";
reg = <0x5a0 0x170>;
#address-cells = <1>;
#size-cells = <1>;
pbias_regulator: pbias_regulator {
compatible = "ti,pbias-omap";
reg = <0x60 0x4>;
0x60 is within the pinmux range of 0x40-0x1d6.
But why is the regulator a sub node here instead of omap4_pmx_core?
syscon =
<&omap4_padconf_global>;
This seems to indicate that 0x60 is supposed to be an offset from
0x5a0. That would require a ranges property in the parent. Is this an
error?
pbias_mmc_reg: pbias_mmc_omap4 {
regulator-name
= "pbias_mmc_omap4";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <3000000>;
};
};
};
};
