Well I can do that, but this should have no effect if we don't define CONFIG_OF_CONTROL. The way I have it we will be able to add more device tree files for sun7x without anyone having to change it. The target should build all sun7i device trees eventually.

Can you do a patch (and prepend it to this one in the next posting of this series), which replaces sunxi's CONFIG_FDTFILE usage with CONFIG_DEFAULT_DEVICE_TREE, dropping the .dtb appending in the defconfigs and instead append the .dtb in include/configs/sunxi-commom.h

3. include/configs/sunxi-common.h

But isn't that used for passing to the kernel? Do you want to drop the ability to have a separate file for each?

A good question, there are 2 things here:

1. This is just the filename, it gets combined with a "basedir" set through extlinux.conf

when booting the real kernel, so they can still be different

2. TBH even if this would make it mandatory for them to be 1 and the same file, I would

not consider that a problem, I would very much like to avoid the need to have separate u-boot and kernel devicetree flavors for sunxi.

OK fair enough, but actually I feel that this should be unrelated to my change. The CONFIG_DEFAULT_DEVICE_TREE setting is used by all boards that use device tree. It seems that CONFIG_FDTFILE is used in a few places but is not very widespread.

So I suppose what I am saying is, how about you do the patch you are talking about? I need to be careful to focus on drivel model changes and not boil the ocearn, or I will never get done!

2. various board/*_defconfig files
3. include/configs/sunxi-common.h

But isn't that used for passing to the kernel? Do you want to drop the ability to have a separate file for each?

A good question, there are 2 things here:

1. This is just the filename, it gets combined with a "basedir" set through extlinux.conf

when booting the real kernel, so they can still be different

2. TBH even if this would make it mandatory for them to be 1 and the same file, I would

not consider that a problem, I would very much like to avoid the need to have separate u-boot and kernel devicetree flavors for sunxi.

OK fair enough, but actually I feel that this should be unrelated to my change. The CONFIG_DEFAULT_DEVICE_TREE setting is used by all boards that use device tree. It seems that CONFIG_FDTFILE is used in a few places but is not very widespread.

So I suppose what I am saying is, how about you do the patch you are talking about? I need to be careful to focus on drivel model changes and not boil the ocearn, or I will never get done!

Ok, I lets leave this bit of the patch as is then, and I'll put fixing this on my todo list.

So...

Thank you, you are very kind :-) I still have a sunxi board and expect to be doing more here in future, but right now am a bit tight for time.

Can you please put this in include/configs/sunxi-common.h instead ?

OK will do.

If you can do a respin based on tip of the latest master and with this one small item fixed, then I'll queue up your patches in u-boot-sunxi/next

I will respin with the changes and retest. I was planning to bring it through -dm with suitable acks, but it is all sunxi stuff now and there are no DM-dependent patches outstanding, so going through sunxi sounds good. But would like to make sure it merges to mainline next week.

This is not correct, a bank have a maximum of 32 gpios but most have less. I assume that this should be the number of actual pins in the bank, correct ?

Well I worry that we need to maintain compatibility with what is there. At some point we can change it, but for now the GPIO numbering is done assuming 32 GPIOs per bank, right?

When everything is moved to driver model I suppose we can be more clever.

Our "gpio-pin-numbers" are based on a sparse numbering scheme assuming 32 pins / bank, and there are assumptions this is the case in various places, so we cannot fix this until we've fully gone dm for all gpio usage. But here it would be nice to have the actual numbers of pins.

Doing so requires at least one table with bank -> number of gpio-s mapping. And I think it may also differ on SoC type in some cases (I would need to take a look at the datasheets)

Hoping this can be in the device tree. Do you have a binding for it?

I suggest keeping this as is for now, and put fixing this with a follow up patch on the todo list, and otherwise this looks good, so this is:

The numbering always assumed 32 GPIOs per bank, just some of them may be empty. IMHO it simplifies register/bit offset conversions, and it's easier to convert the numbers to the designations in the datasheet by hand, for example PA0 = 0, PB0 = 32.

We also do this in the kernel driver. But the bindings are 3 cell: <bank pin flags>.

OK, well we can leave the 'holes' for now.

This is in the (kernel) driver, not the device tree bindings. So we would need to at least add a table for that.

I don't see any pinmux related stuff in this patch. Does the gpio dm handle that?

No, or at least not yet. Does sunxi have kernel support for pinctrl? We could perhaps use that binding if it exists. Otherwise I think the current code is our best bet - we can select the correct serial port based on static configuration (CONFIG) for now.
