[PULL 01/14] hw: arm: aspeed: Enable eth0 interface for aspeed-ast2600-evb

[Cédric Le Goater]

From: Guenter Roeck <linux@roeck-us.net>

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.

[PULL 02/14] hw: arm: aspeed: Enable mac0/1 instead of mac1/2 for g220a

[Cédric Le Goater]

From: Guenter Roeck <linux@roeck-us.net>

According to its dts file in the Linux kernel, we need mac0 and mac1 enabled
instead of mac1 and mac2. Also, g220a is based on aspeed-g5 (ast2500) which
doesn't even have the third interface.

[PULL 03/14] watchdog: aspeed: Sanitize control register values

[Cédric Le Goater]

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.

[PULL 04/14] watchdog: aspeed: Fix sequential control writes

[Cédric Le Goater]

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

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.

[PULL 05/14] hw: aspeed_gpio: Simplify 1.8V defines

[Cédric Le Goater]

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.

[PULL 06/14] hw: aspeed_gpio: Clarify GPIO controller name

[Cédric Le Goater]

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

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

[PULL 07/14] misc/pca9552: Fix LED status register indexing in pca955x_get_led()

[Cédric Le Goater]

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

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.

[PULL 09/14] aspeed: Emulate the AST2600A3

[Cédric Le Goater]

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.

[PULL 10/14] hw/misc: Add Infineon DPS310 sensor model

[Cédric Le Goater]

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.

[PULL 12/14] hw/arm/aspeed: Initialize AST2600 UART clock selection registers

[Cédric Le Goater]

From: Peter Delevoryas <pdel@fb.com>

UART5 is typically used as the default debug UART on the AST2600, but
UART1 is also designed to be a debug UART. All the AST2600 UART's have
semi-configurable clock rates through registers in the System Control
Unit (SCU), but only UART5 works out of the box with zero-initialized
values. The rest of the UART's expect a few of the registers to be
initialized to non-zero values, or else the clock rate calculation will
yield zero or undefined (due to a divide-by-zero).

For reference, the U-Boot clock rate driver here shows the calculation:

    https://github.com/facebook/openbmc-uboot/blob/main/drivers/clk/aspeed/clk_ast2600.c#L357)

To summarize, UART5 allows selection from 4 rates: 24 MHz, 192 MHz, 24 /
13 MHz, and 192 / 13 MHz. The other UART's allow selecting either the
"low" rate (UARTCLK) or the "high" rate (HUARTCLK). UARTCLK and HUARTCLK
are configurable themselves:

    UARTCLK = UXCLK * R / (N * 2)
    HUARTCLK = HUXCLK * HR / (HN * 2)

UXCLK and HUXCLK are also configurable, and depend on the APLL and/or
HPLL clock rates, which also derive from complicated calculations. Long
story short, there's lots of multiplication and division from
configurable registers, and most of these registers are zero-initialized
in QEMU, which at best is unexpected and at worst causes this clock rate
driver to hang from divide-by-zero's. This can also be difficult to
diagnose, because it may cause U-Boot to hang before serial console
initialization completes, requiring intervention from gdb.

This change just initializes all of these registers with default values
from the datasheet.

To test this, I used Facebook's AST2600 OpenBMC image for "fuji", with
the following diff applied (because fuji uses UART1 for console output,
not UART5).

       /* I2C */

Without these clock rate registers being initialized, U-Boot hangs in
the clock rate driver from a divide-by-zero, because the UART1 clock
rate register reads return zero, and there's no console output. After
initializing them with default values, fuji boots successfully.

[PULL 13/14] hw/arm/aspeed: Allow machine to set UART default

[Cédric Le Goater]

From: Peter Delevoryas <pdel@fb.com>

When you run QEMU with an Aspeed machine and a single serial device
using stdio like this:

    qemu -machine ast2600-evb -drive ... -serial stdio

The guest OS can read and write to the UART5 registers at 0x1E784000 and
it will receive from stdin and write to stdout. The Aspeed SoC's have a
lot more UART's though (AST2500 has 5, AST2600 has 13) and depending on
the board design, may be using any of them as the serial console. (See
"stdout-path" in a DTS to check which one is chosen).

Most boards, including all of those currently defined in
hw/arm/aspeed.c, just use UART5, but some use UART1. This change adds
some flexibility for different boards without requiring users to change
their command-line invocation of QEMU.

I tested this doesn't break existing code by booting an AST2500 OpenBMC
image and an AST2600 OpenBMC image, each using UART5 as the console.

Then I tested switching the default to UART1 and booting an AST2600
OpenBMC image that uses UART1, and that worked too.

[PULL 14/14] hw/arm/aspeed: Add Fuji machine type

[Cédric Le Goater]

From: Peter Delevoryas <pdel@fb.com>

This adds a new machine type "fuji-bmc" based on the following device tree:

https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/aspeed-bmc-facebook-fuji.dts

Most of the i2c devices are not there, they're added here:

https://github.com/facebook/openbmc/blob/helium/meta-facebook/meta-fuji/recipes-utils/openbmc-utils/files/setup_i2c.sh

I tested this by building a Fuji image from Facebook's OpenBMC repo,
booting, and ssh'ing from host-to-guest.

I have a pending question with the last patch, do you mind holding
this PR until it is resolved with Cédric and the patch author please?

I guess we can drop the following from the commit log : 

	git clone https://github.com/facebook/openbmc
	cd openbmc
	./sync_yocto.sh
	source openbmc-init-build-env fuji build-fuji
	bitbake fuji-image
	dd if=/dev/zero of=/tmp/fuji.mtd bs=1M count=128
	dd if=./tmp/deploy/images/fuji/flash-fuji of=/tmp/fuji.mtd \

	git clone --branch aspeed-next https://github.com/peterdelevoryas/qemu
	cd qemu

Sounds good. Eventually document that in docs/system/arm/aspeed.rst
in a follow up patch?

I didn't either.

[PULL 04/14] watchdog: aspeed: Fix sequential control writes

[Cédric Le Goater]

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

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.
