PATCH v2 1/1 ARM: sunxi: Change device tree naming scheme for sunxi

There is several different SoCs sharing the sun5i codename: A10s, A12 and A13. Since there is enough differences to not consider those the same SoCs, change a bit the naming scheme to reflect this.

Moreover, some boards like the olinuxino come in A10s and A13 variants, which also share the same SoC codename.

So change the naming scheme to reflect both the codename and the market name of the SoCs used in the dtsi and in the board files

PATCH v2 1/1 ARM: sunxi: Change device tree naming scheme for sunxi

Quoted 11 lines · Maxime Ripard

There is several different SoCs sharing the sun5i codename: A10s, A12 and A13. Since there is enough differences to not consider those the same SoCs, change a bit the naming scheme to reflect this.

Moreover, some boards like the olinuxino come in A10s and A13 variants, which also share the same SoC codename.

So change the naming scheme to reflect both the codename and the market name of the SoCs used in the dtsi and in the board files

Side note:
I just read about the A20 and A31, is there any information and/or source code available for those already, or are they again kept hidden by Allwinner?

Will you take it directly, or do you want a pull request?

There's been a tablet announced with an A31 running Android (the Onda V972), so I guess we can expect a source drop sometime soon, but for the A20, I don't know. It looks like Allwinner even removed all references to that SoC on their website, so...

We can take it directly, but I'm not picking up patches until after the final 4 branches have been sent up and merged.

currently they don't even sell A20 samples, and it was mostly removed from their website (to not compete with the A31 I suppose). for the A31 Tsvetan (olimex.com) was told not even the short datasheet (pins and features) is written yet, and no devkits are available. All A31-based products currently designed (PCBs) and integrated (android) within Allwinner walls.

Chances are very high that the SDKs for these are similar to sun5i ones, i.e. with all allwinner code provided as .o/.ko only... and just enough .h files to be able to compile drivers.

<rant>ARM should *force* all their licensees to respect the GPL. They are profiting for this immoral negligence and that puts ARM itself in the same bucket.</rant>

Only the copyright holders or agents acting on their behalf have the legal power to do that.

Also, it's not in ARMs interest to become a GPL enforcement agency for Linux kernel - their motivation here is to sell more ARM CPUs to that their revenue from their licenses continues to increase, and going after people like this would be counter-productive to that goal.

However, there are organisations setup specifically to deal directly with infringements of open source software licenses on behalf of their copyright holders, and a number of Linux kernel copyright holders have "signed up" with them.

Applied, replacing the previous version I claimed to have applied. ;)
