[PATCH 1/6] ARM: dts: axp209: Add usb_power_supply child node to the ax209 node

[PATCH 1/6] ARM: dts: axp209: Add usb_power_supply child node to the ax209 node

[Hans de Goede]

Add a node representing the usb power supply part of the axp209 pmic, note
that the usb power supply and the (to be added later) ac power supply will
each have their own child-node, so that they can be separately specified
as power-supply for other nodes using a power-supply property with a
phandle pointing to the right axp209 child-node.

would something similar apply to the a20 olimex olinuxino micro/lime2
boards?

is there some documentation how to port devicetree improvements/new
features to all boards or to at least help with that? i think you did
some workshop like that?

i think i have seen other features being added only to some boards?
pwm backlight?
audio output?
but my understanding of all of this is really very limited.

thanks,

a20 olimex olinuxino micro already has this in 4.3-rc1, see:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/sun7i-a20-olinuxino-micro.dts

a20 olimex olinuxino lime2 support is pending:

Applied all the other patches but this one.

Since we dropped the patch adding the regulators support on the
Bananapi until we figure out why the board crash, it doesn't compile
anymore.

Thanks!

Thanks, seems you did not push this to your git.kernel.org repo though ?

How about me doing a v2 of the regulators patch which removes the

&cpu0 {
         cpu-supply = <&reg_dcdc2>;
};

So that we do not get cpu voltage scaling, then the regulator
changes should be a NOP, everything should just keep the u-boot
set voltages, and we can enable oth support.

And then when we've figured out a safe way to enable cpu voltage
scaling we can do so with a follow up patch ?

Is that a plan ? If so say yes and I'll do a v2 of these patches :)

Regards,

Hans

With the new v3 of the regulators patch with the corrected opp-s which
was just send this should no longer be necessary, can you apply the
original "ARM: dts: sun7i: Enable USB DRC on Bananapi" after applying
v3 of the regulators patch please ?

Note there seem to be multiple sdcard slots on the board (4 in total), but
other then mmc0 none of these are hooked up by default, there is a ton of
dip-switches which likely allow hooking some of these up, but the
documentation of the board only describes the use of a fraction of them,
so for now we only support mmc0.
