The SMSC911x Ethernet chip requires a fixed-regulator in order to
function correctly. We have previously provided a means to obtain
this during a Device Tree boot, however nothing has been put into
place when booting with a non-DT kernel. This patch aims to change
that.

Sorry, this patch appears to contain whitespace errors which I missed.
Please wait for v2.

Thanks for fixing this.

No, just select REGULATOR_FIXED_VOLTAGE in apropriate
Kconfig entry, that's simpler. (Suspect under MACH_MOP500.)

Since as you're not #ifdef:in around this entry it will not compile anyway
without fixed regulators.

As noted by Philippe, please drop this hunk off the patch for now.
The AB8500 GPIO is the right one... Probably you're lucky that U-boot
draws the pin high and activates this voltage.
BTW: disablingt the AB8500 pin 26 and thus noting that ethernet screws
up may be a good test for the AB8500 GPIO driver.
Yours,
Linus Walleij

You forgot to add select REGULATOR_FIXED_VOLTAGE to
the MOP500 Kconfig entry, but I added it when applying.

I didn't forget. I intentionally left it out because it's
unconditionally set in the defconfig.

Since disabling that from the config breaks compile this means
that you just broke Arnds randconfig builds :-P
If something *must* be configured for the thing to compile,
so it with select.
