[PATCH 00/15] ARM: dts: sunxi: Add reference-design-tablet.dtsi files + 2 new tablets

[Hans de Goede]

Hi Maxime, Chen-Yu,

Here is a series based on Chen-Yu's suggestion to add a
reference-design-tablet.dtsi file. This works out quite
nicely, resulting in much simpler tablet .dts files, as
well as enabling a bunch of extra features on some tablets,
showing that having to add the same dts bits over and over
again for all model tablets is not a good idea.

This also includes a v2 submission of the new tablet dts
files which sparked the reference-design-tablet.dtsi
discussion.

Regards,

Hans

[PATCH 01/15] ARM: dts: sunxi: Rename sunxi-q8-common.dtsi sunxi-reference-design-tablet.dtsi

[Hans de Goede]

Rename sunxi-q8-common.dtsi to sunxi-reference-design-tablet.dtsi. This
is part of renaming all the sun?i-q8-common.dtsi files to
sun?i-reference-design-tablet.dtsi since most of the hw-config in there
is shared by all sunxi tablets.

[PATCH 02/15] ARM: dts: sun5i: Move q8 display bits to sun5i-a13-q8-tablet.dts

[Hans de Goede]

This is a preparation patch for renaming sun5i-q8-common.dtsi to
sun5i-reference-design-tablet.dtsi and sharing it between all
the A13 tablet dts files.

Since we only have a panel config for the 18 tablets (for now) move
this to the q8 specific dts file.

We could name this mmc0_cd_pin_reference_design and put it in
sun5i-a13.dtsi. We already do this for A10/A20.

This works equally well though.

I would prefer to keep this this way, I was never really fond
of the A10/A20 solution, in retrospect we should have done
a sun4i-a10-reference-design.dtsi defining a lot more stuff
then just the cd_pin.

[PATCH 06/15] ARM: dts: sun5i: Use sun5i-reference-design-tablet.dtsi for dit4350 dts

This results in quite a nice cleanup for this dts file.

Note as a side-effect this also enables the on board speaker / headphones
out. I've tested that this works as advertised.

[PATCH 08/15] ARM: dts: Copy sun8i-q8-common.dtsi sun8i-reference-design-tablet.dtsi

[Hans de Goede]

Copy sun8i-q8-common.dtsi to sun8i-reference-design-tablet.dtsi. This
is part of renaming all the sun?i-q8-common.dtsi files to
sun?i-reference-design-tablet.dtsi since most of the hw-config in there
is shared by all sunxi tablets.

Note that in this case we keep sun5i-q8-common.dtsi as it is shared
between a23 / a33 q8 tablets. Also we leave the usb-wifi config in
there (rather then in sun8i-reference-design-tablet.dtsi) as most
sun8i tablets use sdio wifi rather then usb wifi.

[PATCH 13/15] ARM: dts: sun8i: Add dt node for rtl8703as wifi chip on ga10h

[Hans de Goede]

The ga10h tablet has a rtl8703as wifi chip, add a dt node describing it.

This enables usage of wifi on this tablet (together with the out of
tree rtl8732bs driver).

Shouldn't that need a compatible ?

There is no upstream driver yet, so no devicetree binding for the specific
wifi chip used. But all we really need is to follow generic sdio / network
bindings:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/mmc/mmc-card.txt

Describes how to create a mmc-host child-node describing an (e)mmc-card or
sdio-function, in this case we are adding a node for sdio-function 1,
hence the reg = <1>; in the child-node.

Linux implementation wise, this will make the mmc core set the dev->of_node
ptr to this node for the struct device it passes into the sdio-drivers
probe function.

And u-boot will add a local-mac-address property as documented here:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ethernet.txt

to the node pointed to by ethernet%d aliases.

To actually make use of this I've modified the out of tree driver to check
for the "local-mac-address" property:

https://github.com/jwrdegoede/rtl8723bs/commit/be5e87ea71677120ede457213208902ed9942653

So that each device actually gets a unique address rather then the
(stupid) behavior of the out of tree driver to set the same fixes
mac address on every device which does not have a mac address in
eeprom / nvram.

Since this follows the existing ethernet bindings standard I
believe the dts bits can go upstream as is, but since there
is no upstream-able driver yet, I do not believe that making up
a compatible string to add to the child-node is a good idea.

More-over on q8 tablets we will want to do the same (again for
eeprom / nvram less boards) but without pinning ourselves to
a specific sdio-wifi module / compatible, instead relying on
sdio enumeration to figure out which sdio-wifi module is present.

Regards,

Hans

Both that file and
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/mmc/mmc.txt
list the compatible property as mandatory.

Feel free to raise that issue to the DT maintainers. But this patch
breaks the existing bindings, so it cannot be merged as is.

[PATCH 14/15] ARM: dts: sun8i: Add dts file for Polaroid MID2407PXE03 tablet

[Hans de Goede]

The Polaroid MID2407PXE03 is an a23 based 7" tablet based on a M86_MB V2.0
PCB, featuring a 800x480 LCD, 512MB RAM, 4G NAND, esp8089 wifi, gsl1680
touchschreen, micro-sd slot, 3.5mm headphone jack and a micro-usb otg
connector which doubles as charging port.

Signed-off-by: Hans de Goede <hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
---
Changes in v2:
-Use sun8i-reference-design-tablet.dtsi
-Note this makes the dts pretty much empty for now, this will change
 once the touchscreen driver + some mmc-pwrseq changes for the sdio wifi
 land upstream

Beside the minor comment on patch 13, applied everything.

Thanks, this is a very nice cleanup.
