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?

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

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

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.

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

Hi Maxime,
sorry I forgot to mark it as a v2 and add the changelog to v1.

I've actually not split the patch into two on purpose as it's a pretty small 
change and the patch adding support for the A83T didn't split out the device 
tree changes - and recently in another patch of mine, the extra devicetree 
patch was squashed into the driver patch by the maintainer while merging. I'll 
fix this up asap.

You should have a changelog detailing which changes you made to your
patch with the previous version, and why you made those changes (for
example because we looked at the a83t datasheet and found the two
controllers to be very similar).

The bindings and the dt changes should be two different patches as
well.
