[U-Boot] [PATCH 0/6] sunxi: update Pine64/A64 DTs

[U-Boot] [PATCH 0/6] sunxi: update Pine64/A64 DTs

[Andre Przywara]

Hi,

in the wake of the sunxi DM enablement series it became apparent that
the current device tree files for the A64 SoC and its board are outdated.

Since Linux v4.10-rc1 there are now basic .dts files for the Allwinner
A64 SoC and the Pine64 boards in the mainline kernel.
Linux v4.11-rc1 added MMC and USB support.
Because our preliminary device trees used in U-Boot differ significantly,
let's update our copy with what's in the current Linus' master tree.
Since in contrast to U-Boot the kernel still lacks support for Ethernet,
we keep our preliminary nodes for that IP, but adjust it slightly to
match the new clocks and reset bindings.

As the sun8i-emac driver is actually using the DT for the pinmux setup,
we teach it how to cope with the new pinctrl bindings in the first two
patches. This is probably becoming somewhat obsolete very soon (with
DM GPIO support on the list already), however I consider these two
patches as merely fixes for the existing driver to maintain bisectability.
It would make sense to merge the new DTs before the DM patches, so we
need to have something in place which works meanwhile.

Let me know what you think.

Cheers,
Andre.

[U-Boot] [PATCH 1/6] sunxi: GPIO: introduce sunxi_gpio_setup_dt_pins()

[Andre Przywara]

Instead of hard-coding GPIO pins used for a certain peripheral, we
should just use the pinctrl information from the DT.
The sun8i-emac driver has some simple implementation of that, so
let's just generalize this and move the code into a more common
location.
On the way we add support for the new, generic pinctrl binding now
used by all Allwinner SoCs.

You should use a different default, something invalid.

As the defaults implied by the bindings are to not touch the settings
if they aren't specified, as in "whatever the hardware was set to".
This applies to both drive strength and bias/pull.

That function already exists, sunxi_name_to_gpio.

Indeed, I found this yesterday _after_ sending the patches ;-)
For some reasons I missed that when I originally wrote the patches,
sorry for that.

[U-Boot] [PATCH 2/6] net: sun8i-emac: use new, generic GPIO setup routine

[Andre Przywara]

Instead of open-coding the fairly generic pinmux setup in the sun8i-emac
driver, let's just use the new common implementation of that.
This has also the advantage of supporting the newpinctrl bindings, so
the driver can cope with the upstream Linux DTs.

[U-Boot] [PATCH 3/6] sunxi: dts: update sun50i-a64.dtsi from Linux

[Andre Przywara]

Now with USB and MMC for the A64 supported in mainline Linux, let's
sync our DT with what's in the official Linux repository.
This completely changes the clock representation, but U-Boot doesn't
use this anyway.
Also it switches to a new pinctrl binding, which uses generic property
names.
The only user of that was the sun8i-emac, which has just learned
how to deal with this. Since mainline Linux does not support this
Ethernet IP yet, let's copy over our previous DT nodes for that,
adjusting them to match the new clock and pinctrl bindings.

[U-Boot] [PATCH 4/6] sunxi: dts: update Pine64 .dts

[Andre Przywara]

Update the two .dts files for the Pine64 boards with those used in the
kernel. This switches from using a -common.dtsi to including the .dts
for the non-plus model in the -plus file.
Again we keep our EMAC driver nodes in, which are not yet in mainline
Linux.

[U-Boot] [PATCH 5/6] sunxi: dts: remove now obsolete pine64-common.dtsi

[Andre Przywara]

Now since the common DT nodes between the two Pine64 boards have been
moved into the .dts for the non-plus model, we no longer need the
extra -common.dtsi.
Let's just remove it.

[U-Boot] [PATCH 6/6] sunxi: dts: add Bananapi M64 .dts

[Andre Przywara]

Since mainline Linux gained support for the BananaPi-M64, let's just
copy this DT to prepare the U-Boot support for that board.
Again add the required DT nodes for the Ethernet IP.

Could we keep this simple, and just do a "sync with the kernel" commit for
sun50i, which also keeps the sun8i-emac specific bits. And also explicitly
mention the git commit or tag you are syncing to.

So you mean to drop patch 1 and 2 and keep the old style pinctrl
bindings around for the EMAC node?
I can certainly do this (if others agree), but didn't want to dodge a
more proper solution in the first place.

Another alternative would be to squash the functionality of patch 1
directly into sun8i_emac.c, so without the moving to pinmux.c. This
would mean dropping patch 1/6 and just having a fix for the sun8i_emac.

Let me know what's the preferred solution here.

Cheers,
Andre.

I've actually no preference on this. What I meant was you don't need
four patches to do the sync-up, just one, i.e. copy sun50i*.{dts,dtsi}
from the kernel, and patch back whatever the emac needs, since it's
not in mainline yet.

I guess you could update sun8i-emac to deal with generic pinconf,
or update the gpio driver, but that would be a separate series.

Agree with ChenYu, and will update the status on this on patchwork as
"Superseded"

thanks!
