[v2,04/12] riscv: dts: allwinner: Add the D1/D1s SoC devicetree
Commit Message
D1 (aka D1-H), D1s (aka F133), R528, and T113 are a family of SoCs based
on a single die, or at a pair of dies derived from the same design.
D1 and D1s contain a single T-HEAD Xuantie C906 CPU, whereas R528 and
T113 contain a pair of Cortex-A7's. D1 and R528 are the full version of
the chip with a BGA package, whereas D1s and T113 are low-pin-count QFP
variants.
Because the original design supported both ARM and RISC-V CPUs, some
peripherals are duplicated. In addition, all variants except D1s contain
a HiFi 4 DSP with its own set of peripherals.
The devicetrees are organized to minimize duplication:
- Common perhiperals are described in sunxi-d1s-t113.dtsi
- DSP-related peripherals are described in sunxi-d1-t113.dtsi
- RISC-V specific hardware is described in sun20i-d1s.dtsi
- Functionality unique to the D1 variant is described in sun20i-d1.dtsi
The SOC_PERIPHERAL_IRQ macro handles the different #interrupt-cells
values between the ARM (GIC) and RISC-V (PLIC) versions of the SoC.

Changes in v2:
- Split into separate files for sharing with D1s/R528/T113
- Use SOC_PERIPHERAL_IRQ macro for interrupts
- Rename osc24M to dcxo and move the frequency to the board DTs
- Drop analog LDOs due to the missing binding
- Correct tcon_top DSI clock reference
- Add DMIC, DSI controller, and DPHY (bindings are in linux-next)
- Add CPU OPP table

Is this "additionally contain" or a case of the D1 is the R528 but with
s/arm/riscv/? It's the latter, right?

Modulo the warnings I replied to the cover with & one minor comment

Since this is a "must", can you drop the clock-frequency = <0> here so
that if someone doesn't override it in their board dt-validate
complains?
Thanks,
Conor.

So I compared all the reg and interrupts properties against the T113
manual, they match, as far as they are described there. The undocumented
rest matches what we already have in other SoCs.
I noticed two things, though, mentioned inline below:

The clocks and the two mixers are not children of a bus node anymore,
IIUC correctly this was to manage the SRAM control. Is that now handled
differently, or does the D1 generation not require this anymore?

This is the same interrupt number as for the DSI controller above. Is
that correct, and can the drivers handle that?

The D1 family uses the DSP SRAM for extra space during early boot --
this applies even to D1s, where the DSP is fused off. Since the DE SRAM
is not used for this purpose, the "SRAM C" aka "boot mode" bit in the
SRAM controller is cleared by default, thus mapping the DE SRAM to the
peripheral. So the DE works without touching the syscon registers.
However, if I set the SRAM C bit, the DE stops working. So having the
bus node would make some sense. But I do not know any address for the
SRAM -- there is no "boot" address, and the "peripheral" address may not
even be accessible to the CPU. So it is not possible to represent this
with a mmio-sram node like the binding requires.
So I suppose we should either change the binding to allow a child
allwinner,sun50i-a64-sram-c node with no address (the driver should work
fine with this); or leave out the bus, and people who go poking around
in the syscon registers get to keep the pieces. :)

Yes, it is correct. Currently, neither driver uses the interrupt, so we
will just need to keep the sharing in mind if/when that happens.

The D1-H user manual says starting from interrupt number 176, interrupts are
CPUX related which I assume are CPU internal interrupts?
If yes, for external ones, valid interrupt source range is [1, 175]. And this
field should be 175, no?

While the overall dt looks good to me, it seems others did find
some minor issues. But I can at least provide a
Tested-by: Heiko Stuebner <heiko.stuebner@vrull.eu>
as it could sucessfully boot the Nezha variant of boards for me.

Technically they're the same die, but the CPU cores are selectively
enabled, and at least what Allwinner says is that D1 contains only RV
and R528 contains only ARM.

I think this should be correct, and only one driver acquires IRQ now.
