Hey Samuel,
Apologies for the last email, the first 5 patches in this series
didn't correctly land in my inbox and I skimmed & replied to the
wrong cover letter... I blame it being pre 8 AM ;)

This series adds the Kconfig/defconfig plumbing and devicetrees for a
range of Allwinner D1-based boards. Many features are already enabled,
including USB, Ethernet, and WiFi.

The SoC devicetree uses bindings from the following series which have
not yet been merged:
- SRAM controller:
   https://lore.kernel.org/lkml/20220815041248.53268-1-samuel@sholland.org/ (local)
- NVMEM cell bits property change:
   https://lore.kernel.org/lkml/20220814173656.11856-1-samuel@sholland.org/ (local)
- In-package LDO regulators:
   https://lore.kernel.org/lkml/20220815043436.20170-1-samuel@sholland.org/ (local)

All three of these are required to set the correct I/O domain voltages
in the pin controller, which I would consider important to have in the
initial version of the devicetree.

The SoC devicetree does contain one small hack to avoid a dependency on
the audio codec binding, since that is not ready yet: the codec node
uses a bare "simple-mfd", "syscon" compatible.

I tried this series on top of both 6.0-rc1 & next, but I saw a shed
load of errors from dtbs_check. I'll take a look at the rest of the
series later on, but just FYI. This time I did at least read the
right cover letter and actually applied your dependent series..
/facepalm

I have been trying to get riscv down to 0 warnings and would not be
in favour of accepting patches that go in the other direction.
(This patchset currently produces about 47 new warnings)

Only 4 unique ones :)

Thanks for checking this. I had done a couple of passes cleaning things up. The
remaining warnings are the ones I was unsure how to fix.

FWIW this is what I see, LMK if I am missing something.
allwinner/sun20i-d1-lichee-rv.dtb: i2c@2502000: Unevaluated properties are not allowed ('dma-names', 'dmas' were unexpected)

This one is new with dt-schema 2022.08.1 (I was previously on d1f3102e locally).
I'm not sure if it is a bug in the binding or in the dt-schema tool. The
warnings go away if I do:

But I wouldn't expect this to be necessary, since dma.yaml has "select: true".
Compare the this with the UARTs. Neither serial/snps-dw-apb-uart.yaml nor
serial/serial.yaml references any DMA properties, yet there is no warning for those.

The new compatible is in linux-next. I can add it to the cover letter for v2:

allwinner/sun20i-d1-lichee-rv.dtb: ethernet@4500000: Unevaluated properties are not allowed ('mdio', 'reset-names', 'resets' were unexpected)

This showed up with a dt-schema update in the last year or so. This may be a bug
in the binding? allwinner,sun8i-a83t-emac.yaml picks up these three properties
from snps,dwmac.yaml, but does not have them in its own "properties" block.
(resets and reset-names are even in "required"!)

allwinner/sun20i-d1-lichee-rv-86-panel-720p.dtb: ethernet@4500000: Unevaluated properties are not allowed ('phy-supply' was unexpected)
allwinner/sun20i-d1-dongshan-nezha-stu.dtb: ethernet@4500000: Unevaluated properties are not allowed ('phy-supply' was unexpected)

I think this one is just flat out missing from the binding. It is present in the
other two Allwinner Ethernet MAC bindings, but not this one.

Samuel
