According to the datasheet of ASPEED SOCs, a GPIO controller owns 4KB of
register space for AST2700, AST2500, AST2400 and AST1030; owns 2KB of
register space for AST2600 1.8v and owns 2KB of register space for
AST2600 3.3v.

It set the memory region size 2KB by default and it does not compatible
register space for AST2700.

Introduce a new class attribute to set the GPIO controller memory size
for different ASPEED SOCs.

It set "aspeed_gpio_ops" struct which containing read and write callbacks
to be used when I/O is performed on the GPIO region.

Besides, in the previous design of ASPEED SOCs, one register is used for
setting one function for 32 GPIO pins.
ex: GPIO000 is used for setting data value for GPIO A, B, C and D in AST2600.
ex: GPIO004 is used for setting direction for GPIO A, B, C and D in AST2600.

However, the register set have a significant change in AST2700.
Each GPIO pin has their own control register. In other words, users are able to
set one GPIO pin’s direction, interrupt enable, input mask and so on
in one register. The aspeed_gpio_read/aspeed_gpio_write callback functions
are not compatible AST2700.

Introduce a new "const MemoryRegionOps *" attribute in AspeedGPIOClass and
use it in aspeed_gpio_realize function.

The interrupt status field is W1C, where a set bit on read indicates an
interrupt is pending. If the bit extracted from data is set it should
clear the corresponding bit in reg_value. However, if the extracted
bit is clear then the value of the corresponding bit in reg_value
should be unchanged.

SHARED_FIELD_EX32() extracts the interrupt status bit from the write
(data). reg_value is set to the set's interrupt status, which means
that for any pin with an interrupt pending, the corresponding bit is
set. The deposit32() call updates the bit at pin_idx in the
reg_value, using the value extracted from the write (data).

The result is that if multiple interrupt status bits
were pending and the write was acknowledging specific one bit,
then the all interrupt status bits will be cleared.
However, it is index mode and should only clear the corresponding bit.

For example, say we have an interrupt pending for GPIOA0, where the
following statements are true:

   set->int_status == 0b01
   s->pending == 1

Before it is acknowledged, an interrupt becomes pending for GPIOA1:

   set->int_status == 0b11
   s->pending == 2

A write is issued to acknowledge the interrupt for GPIOA0. This causes
the following sequence:

   reg_value == 0b11
   pending == 2
   s->pending == 0
   set->int_status == 0b00

It should only clear bit 0 in index mode and the correct result
should be as following.

   set->int_status == 0b11
   s->pending == 2

   pending == 1
   s->pending == 1
   set->int_status == 0b10

AST2700 integrates two set of Parallel GPIO Controller with maximum 212
control pins, which are 27 groups. (H, exclude pin: H7 H6 H5 H4)

In the previous design of ASPEED SOCs, one register is used for setting
one function for one set which are 32 pins and 4 groups.
ex: GPIO000 is used for setting data value for GPIO A, B, C and D in AST2600.
ex: GPIO004 is used for setting direction for GPIO A, B, C and D in AST2600.

However, the register set have a significant change since AST2700.
Each GPIO pin has their own individual control register.
In other words, users are able to set one GPIO pin’s direction,
interrupt enable, input mask and so on in the same one register.

Currently, aspeed_gpio_read and aspeed_gpio_write callback functions
are not compatible AST2700.

Introduce new aspeed_gpio_2700_read and aspeed_gpio_2700_write callback
functions and aspeed_gpio_2700_ops memory region operation for AST2700.
Introduce a new ast2700 class to support AST2700.

The register set of GPIO have a significant change since AST2700.
Each GPIO pin has their own individual control register and users are able to
set one GPIO pin’s direction, interrupt enable, input mask and so on in the
same one control register.

AST2700 does not have GPIO18_XXX registers for GPIO 1.8v, removes
ASPEED_DEV_GPIO_1_8V. It is enough to only have ASPEED_DEV_GPIO
device in AST2700.

The AST2700 GPIO controller interrupt is connected to GICINT130_INTC at
bit 18. Therefore, correct GPIO irq 130.

Thanks, that looks way simpler now!

Hi all,

> Subject: [PATCH v7 0/8] Support GPIO for AST2700

I don't know why I send this patch series failed to the following email addresses and got the following errors.
open list:All patches CC here <qemu-devel@nongnu.org> 
open list:ASPEED BMCs <qemu-arm@nongnu.org>

2024/10/1 上午 06:43:04 - Server at nongnu.org (2001:470:142:3::10) returned '451 4.4.397 Error communicating with target host. -> 421 4.2.1 Unable to connect ->
SocketError: Failed to connect. Winsock error code: 10051, Win32 error code: 10051'

Do you encounter the same issue?
If no, I will re-send this patch series with Thomas reviewed tag in v8.

Thanks-Jamin

There seem to be an issue with the mailing list. I don't know what
though.

> If no, I will re-send this patch series with Thomas reviewed tag in v8.

I think we are done with this series. I was going to apply it to
aspeed-next when I noticed b4 was not able to retrieve the patchset.
And I don't see much changes in https://patchew.org/QEMU.

So please wait a bit before resending. No hurries.

Thanks,

C.

Applied to aspeed-next.

Thanks,

The data centre hosting the GNU servers (including the mailing
list server for nongnu.org lists) had an outage earlier, and
everything was inaccessible. It should all be back up now, I think.
