[PATCH v2] arm: sun4i: Add support for Pengpod 1000 tablet

[PATCH v2] arm: sun4i: Add support for Pengpod 1000 tablet

[Bob Ham]

This is initial support for the Pengpod 1000 tablet.  The display is
not currently working but the UART, SD card and USB all work fine.

And this is redundant with the SPDX header.

These two pinctrl property aren't needed.

Each step should increase the perceived brightness by roughly 1/Nth, N
being the number of steps. Usually PWM backlights don't work like that.

You can drop these two pinctrl properties as well

And all these nodes.

The X11 license notice states explicitly that the notice has to be
included in the file.  Wouldn't removing it be a violation of the license?

FYI, this was copied from another .dts file.  All of the other
brightness-levels settings in sun{4,5,7}i .dts files follow similar
patterns:

sun4i-a10-dserve-dsrv9703c.dts:               brightness-levels = <0 10
20 30 40 50 60 70 80 90 100>;
sun4i-a10-inet1.dts:          brightness-levels = <0 10 20 30 40 50 60
70 80 90 100>;
sun4i-a10-pov-protab2-ips9.dts:               brightness-levels = <0 10
20 30 40 50 60 70 80 90 100>;
sun5i-a13-empire-electronix-d709.dts:         brightness-levels = <0 10
20 30 40 50 60 70 80 90 100>;
sun5i-a13-utoo-p66.dts:       brightness-levels = <0 30 40 50 60 70 80
90 100>;
sun5i-gr8-evb.dts:            brightness-levels = <0 10 20 30 40 50 60
70 80 90 100>;
sun7i-a20-wexler-tab7200.dts:         brightness-levels = <0 10 20 30 40
50 60 70 80 90 100>;

I'll take the brightness-levels from sun8i-a83t-tbs-a711.dts which
follows a more appropriate pattern:

sun8i-a83t-tbs-a711.dts:              brightness-levels = <0 1 2 4 8 16
32 64 128 255>;

The SPDX header is explicitly here to remove the license text and
create a tag that is in a indirect reference to the license text in
LICENSES. It's not going away.

I never said we were perfect reviewers. Feel free to help in the process.

Well, the top bit that I quoted above says that the licenses refer to
only that one file in particular and not the project as a whole.  Then
the X11 license states that the notice can't be removed from 'this
software and associated documentation files (the "Software")' which
would seem to refer to the single file.  Therefore, removing the notice
from the single file and replacing it with an SPDX header would seem to
violate the license.

It's a fine point but it makes me nervous.  I originally based my .dts
on sun4i-a10-inet1.dts.  I've CC'd the original copyright holder, Hans
de Goede.  Hans, are you willing to give permission for the license
notice to be replaced with just an SPDX header indicating the dual
licensing?

While we're at it, there are a number of other files with the same
license text.  Hans, are you prepared to give permission for your other
license notices to be replaced with SPDX headers?

Thanks,

Bob

Yes that is fine by me and you've my permission to switch to using
just the SPDX header.

FWIW I do not believe the "can't be removed from 'this software and
associated documentation files (the "Software")'" language
applies to the software as a whole and not individual files.

Yes you may make the same change to all files with my copyright.

Hans
