Hi everyone,
this patch adds the DT for the [[Inet-K970] tablet.
Note that the wiki page has been renamed from [[Tristan-Auron-Planet-1]]
after identifying the mainboard. Earlier patches concerning U-Boot and
FEX have been filed under original name to this list and are now somewhat
in limbo. FEX is checked in, U-Boot on hold to the best of my knowledge.
Should I post a rename patch for the FEX and repost the unchanged U-boot
patch for the device under the new name or how to proceed best?
Kind regards, Lars
Thanks, we've recently moved over from using a full node
hierarchy to using label references in board dts files, see e.g. :
https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git/commit/?h=sunxi/dt-for-3.20&id=327f121fea91fd79d6b71f47a8e1bc62a7fd86e5
Can you please respin this to follow that style (the nodes should
be sorted alphabetically).
Also like with the u-boot patch, when submitting patches for upstream
they should not be send to the linux-sunxi list, sunxi dts patches
should go to Maxime Ripard (added to the Cc) with the linux-arm and
devicetree lists both in the Cc (also added to the Cc) note you do
not need to be subscribed to these lists.
This makes me realize that we should probably write a manual on
how to add a new sunxi board to upstream u-boot / a dts to the
kernel. Since you've just gone through the process, could you
perhaps write a manual for this on linux-sunxi.org, it is a wiki
so you should be able to add an account and create a new page,
note I've also asked Aleksei Mamlin (also added to the Cc) to
create a manual for this, so if you do please coordinate with
him to avoid doing double work. Also note that me asking you
both is not an excuse for the both of you to look at the other
for doing this, but rather me hoping that at least one of you
will do it :)
Thanks & Regards,
Hans
