Hi,

As usual, a couple of fixes and small extensions. There is also a
minimal DPS310 sensor model, which needs a little more review.

Thanks,

C.

Commit 7582591ae7 ("aspeed: Support AST2600A1 silicon revision") switched
the silicon revision for AST2600 to revision A1. On revision A1, the first
Ethernet interface is operational. Enable it.

From: Andrew Jeffery <andrew@aj.id.au>

While some of the critical fields remain the same, there is variation in
the definition of the control register across the SoC generations.
Reserved regions are adjusted, while in other cases the mutability or
behaviour of fields change.

Introduce a callback to sanitize the value on writes to ensure model
behaviour reflects the hardware.

The logic in the handling for the control register required toggling the
enable state for writes to stick. Rework the condition chain to allow
sequential writes that do not update the enable state.

From: Joel Stanley <joel@jms.id.au>

There's no need to define the registers relative to the 0x800 offset
where the controller is mapped, as the device is instantiated as it's
own model at the correct memory address.

Simplify the defines and remove the offset to save future confusion.

There are two GPIO controllers in the ast2600; one is 3.3V and the other
is 1.8V.

There was a bit of a thinko in the state calculation where every odd pin
in was reported in e.g. "pwm0" mode rather than "off". This was the
result of an incorrect bit shift for the 2-bit field representing each
LED state.

From: Joel Stanley <joel@jms.id.au>

This is the latest revision of the ASPEED 2600 SoC. As there is no
need to model multiple revisions of the same SoC for the moment,
update the SCU AST2600 to model the A3 revision instead of the A1 and
adapt the AST2600 SoC and machines.

Reset values are taken from v8 of the datasheet.

From: Joel Stanley <joel@jms.id.au>

This contains some hardcoded register values that were obtained from the
hardware after reading the temperature.

It does enough to test the Linux kernel driver. The FIFO mode, IRQs and
operation modes other than the default as used by Linux are not modelled.

Witherspoon uses the DPS310 as a temperature sensor. Rainier uses it as
a temperature and humidity sensor.

Alternatively easier to review:

           } else {
               if (!enable && aspeed_wdt_is_enabled(s)) {

Is it a bugfix? Otherwise this is annoying.

Maybe:

 #define AST2600A1_CLK_SEL3          TO_REG(0x310)
 #define AST2600A3_CLK_SEL3          TO_REG(0x308)

... use AST2600A3_CLK_SEL3 here?

So someone wanting the emulate the A1 doesn't get
the nasty bug of having CLK_SEL3 misplaced.
