I really hate these lists in bindings:

These are all hardware constants, they should come from the data sheet and
get put into the dtsi file. The driver doesn't care what they are, and
the binding doesn't care, this only serves to make the binding less
generic.

For these, it's different: There is nothing wrong putting macros like
these into DT, because they will be the same across all SoCs.

However, as I mentioned in my reply to patch 8, I don't think that information
belongs into DT, and it should be in the device driver instead, because
that already knows the direction and transfer width and has to set it
through the slave config interface anyway.

They serve to make the dts file significantly more readable and
give some small level of compile-time checking to the dts file.

I am entirely in favour of them and its the direction that we
have been moving in for shmobile bindings.

I don't really mind either way on these, when we had the
configuration for each slave in the dma-controller node
then having defines was very sensible.

There are a couple of issues here, firstly is that I have no idea if
any other SoCs have control bits that are not currently configurable
from the information supplied by a driver when it is bound.

The second is that the DMA for some peripherals do not match the size
of the registers, for example the SDHI blocks can do 256bit DMA to
what is specified to be a 32bit register.

I also prefer these to be in one place, to avoid the following

- Altering every $OS run on the system when you add a new dma peripheral
- Having to cross merge adding to DTS/DTSI and a driver for the same.

These are the only ones that se different for r8a7791 (0x51 etc.
compared to 0x81).
Wondering whether someone mixed up decimal and hexadecimal...

Are the System DMAC and Audio DMAC ID spaces separate
or unified? We also have in the audio section:

#define R8A7790_DMA_SSCI92_TX   (0x81)
#define R8A7790_DMA_SSCI92_RX   (0x82)
#define R8A7790_DMA_SCU0        (0x85)

> +#define R8A7790_DMA_IIC3_TX    (0x77)
> +#define R8A7790_DMA_IIC3_RX    (0x78)

In all other places, we call this "IICDVFS" instead of "IIC3".
The docs aren't always that consistent, though.

R8A7790_DMA_AXISTATS3C, to match the docs?

AXSTM is missing at the end:

This section is duplicated.

From my (still-limited) understanding of the shdma driver, these look like
pure register values, not descriptions of the hardware?

Confirmed. They should be 0x51, 0x52, 0x55, 0x56.
