This series adds support for the recently released Allwinner H5 SoC [1] and the Orange Pi PC 2 board [2]. This exercise is rather easy this time, since the new SoC is very similar to the existing H3 SoC and can thus share a lot of support. To express this, the first patch splits the H3 .dtsi to allow reusing it later. The last two patches add the H5 .dtsi and the .dts for the first available board featuring this chip, based on that shared base DT. This is some early version, it's based on a merge of various -for-4.10 branches from Maxime's repository. I can boot this on the OPi board and MMC and USB seem to work fine. I haven't tested any other peripherals yet. Some open issues: - The naming: Following the Allwinner scheme this should be "sun50i-h5" (which I use in this series), but it shares so much with the H3 that "sun8i-h5" wouldn't be wrong either. It gets a bit weird with that shared .dtsi, which I call sun8i-h3-h5.dtsi for now. - The clocks and pinctrl look _almost_ similar. I may sound like a broken record, but our habit of requiring kernel support for those almost identical SoCs really bites us now. As the MMC got updated, I fear there is _one_ additional pin that we need for the HS400 transfer mode. Also I am afraid the MMC clock may be slightly different due to the advanced MMC support. At the moment this is not an issue, as the driver only support DDR50 at most anyway, so we get away with it now. I wonder if it's feasible to add those things to the existing H3 clocks and pinctrl to avoid another set of drivers. - I just see that I missed those patches that add just the names to the binding docs. I will send them once we agreed on the naming. Let me know what you think. Cheers, Andre.
