The controller is pretty different on the A64 compared to the A10. The
A10 has two channels for example, while the A64 has only one.
It looks like the one in the A83t though, so you can use that
compatible instead.

Hi,
Looking at the patch for the A83t, the only difference is that it uses a 3/4 instead of a 2/3 voltage divider, nothing is changed with the channels. But I'm also not sure which one (or a different one) is used from looking at the "A64 User Manual".
Thanks, Luca

I guess you can reuse the A83t compatible here then, and a more
specific a64 compatible in case we ever need to fix this.

I'm sorry, what are you referring to with "one" in that sentence?

Hi,
Sorry, I meant I didn't find anything in the A64 user manual whether a 3/4 or a 2/3 voltage divider (or one with different values) is used on the A64.

Ok :)
I guess you can just reuse the A83t compatible then, together with the
A64's.

Hi Maxime,
I'd submit a v2 with these changes to v1 then:
lradc: lradc@1c21800 {
- compatible = "allwinner,sun4i-a10-lradc-keys";
- reg = <0x01c21800 0x100>;
+ compatible = "allwinner,sun50i-a64-lradc-keys",
+ "allwinner,sun8i-a83t-r-lradc";
+ reg = <0x01c21800 0x400>;
interrupts = <GIC_SPI 30 IRQ_TYPE_LEVEL_HIGH>;
status = "disabled";
};
Does that look okay?
The reg change is due to me not spotting the address being 0x01C2
1800---0x01C2 1BFF, so the size should be 0x400 and not 0x100.
Thanks for the feedback,
Luca

It would be great to drop the -keys from the compatible, and to
document the bindings
Looks good otherwise

Hi again,
So I should just document the "allwinner,sun50i-a64-lradc" string in
Documentation/devicetree/bindings/input/sun4i-lradc-keys.txt ? Don't I also
have to add the compatible to the driver code then? Just adding the a64
compatible to a dts wouldn't work without that.
Thanks, Luca

What I meant was that you needed both, something like:
compatible = "allwinner,sun50i-a64-lradc", "allwinner,sun8i-a83t-lradc";
That way, the OS will try to match a driver for the A64 compatible if
any, and fallback to the A83's otherwise. And since we don't have any
quirk at the moment, there's no change needed to the driver.

Hi Maxime,
sorry for the long back and forth, I hope I understood you correctly now.
Here's what I would submit as v2 then (I'll split the two files into seperate
patches as the devicetree documentation suggests)
Documentation/devicetree/bindings/input/sun4i-lradc-keys.txt:
- compatible: should be one of the following string:
"allwinner,sun4i-a10-lradc-keys"
"allwinner,sun8i-a83t-r-lradc"
+ "allwinner,sun50i-a64-lradc", "allwinner,sun8i-a83t-r-lradc"
arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi:
+ lradc: lradc@1c21800 {
+ compatible = "allwinner,sun50i-a64-lradc",
+ "allwinner,sun8i-a83t-r-lradc";
+ reg = <0x01c21800 0x400>;
+ interrupts = <GIC_SPI 30 IRQ_TYPE_LEVEL_HIGH>;
+ status = "disabled";
+ };
+
Thanks,
Luca
