Changes v2:
- Update SPDX short identifier
- Remove gpio-keys-polled device moved to arch/x86/platform
- Fix styling
- Use spinnlock only there where it is useful
- Removed useless output on driver load
- Do bit manipulation later not on IO
- Add additional GPIOs handling mpci2_reset and mpcie3_reset.
- Add name to GPIOs exported via sysfs
Changes v3:
- Add a new platform device for the frontpanel push button.
- Get global variables from the heap
- Fix errors/warnings generated by ./scripts/checkpatch.pl
Changes v4:
gpio-apu.c
- Move bit shifting out of spinnlock
- Change declaration of int to unsigned int
- Remove redundant blank line
- Use dmi table callback
- Remove noise
pcengines-apu-platform.c
- Move platform device to drivers/platform/x86
- Remove needless include
- Add dmi information so that this device is only present on APU2
APU3 boards from PC Engines
Changes v5:
gpio-apu.c
- Remove GPIO_GENERIC select from Kconfig
- Make gpio_chip real member of apu_gpio_pdata
- Use BIT macro for get_data and get_dir functions
- Pass platform data to devm_gpiochip_add_data to get data
per-instance state container
- Remove DEVNAME define
- Remove platfrom_device member from apu_gpio_pdata this
- Clean up init function
- Remove MODULE_ALIAS
Until now it was not possible to get more information to detect the
MMIO_BASE address from the ACPI subsystem.

2.11.0
Add a new device driver "gpio-apu" which will handle the GPIOs on APU2
and APU3 devices from PC Engines.
APU2 (https://pcengines.ch/schema/apu2c.pdf page 7):
- G32 is "button_reset" connected to the smd-button on the frontpanel
- G50 is "mpcie2_reset" connected to mPCIe2 reset line
- G51 is "mpcie3_reset" connected to mPCIe3 reset line
APU3 (https://pcengines.ch/schema/apu3c.pdf page 7):
- G32 is "button_reset" connected to the smd-button on the frontpanel
- G50 is "mpcie2_reset" connected to mPCIe2 reset line
- G51 is "mpcie3_reset" connected to mPCIe3 reset line
- G33 is "simswap" connected to SIM switch IC to swap the SIM between
mPCIe2 and mPCIe3 slot

There is no need to do ~ under spin lock.

(2)
I think I have already told about (1) and (2). You may create two
callbacks and utilize .callback member in DMI table.

I don't think we need this.

After removing unneeded checks why not to simple use
module_platform_driver()
?

Yep, and actually this one has to instantiate a GPIO.

I'm sorry if I already asked, please, remind me where dump of ACPI
tables can be found?
Also would be nice to have the output of `lspci -nk -vv -xxx` on such platform.

Hello Andy,
Thank you very very much for your code review "again" I will update my
patch set with your hints.
Should I send v6 or should i wait till I get feedback from you about
ACPI?

Thank you for your hints and time
It would be nice if you could fix ACPI problemmatik.

I would like to see the ACPI dump for that...

Thanks!
So, let me clarify what we have:
- some platforms are in the wild with old BIOS with broken ACPI tables
- you still may fix the things for new BIOS version for all affected platforms
- you need to support both
Is this all correct?
For broken firmware you need to do the following:
- create an MFD driver, which would instantiate GPIO and GPIO keys
support (at least)
- create one of each above drivers w/o any DMI crap (should be done
as a part of MFD driver)
For fixed BIOS you need to add the following (example, not a fully
correct solution) at the level behind SB:
Scope (SB)
{
Device(GPIO)
{
Name (_ADR, Zero) // _ADR: Address
Name (_HID, "AMDxxxx") // One ID per platform, so, APU2 :
1, APU 3: 1 => 2 unique IDs, in this case no need to add neither _HRV
nor _UID
Name (_HRV, 2) // Other approach is to have one ID
but different _HRV: e.g. 2 for APU2, 3 for APU3
Name (_UID, Zero) // Another approach is to have one
device per community of pins and several _UID:s
Name (_DDN, "AMD APU General Purpose Input/Output (GPIO) controller")
Method (_CRS, 0, NotSerialized)
{
Name (RBUF, ResourceTemplate ()
{
Memory32Fixed (ReadWrite,
0xFED80000 // + offset + community0 offset
0x0000xxxx, // + size of the community0
)
...
Memory32Fixed (ReadWrite,
0xFED80000 // + offset + communityN offset
0x0000xxxx, // + size of the communityN
)
/* IRQ resource if needed and present on real HW */
Interrupt (ResourceConsumer, Level, ActiveLow, Shared, ,, )
{
0x000000xx,
}
})
Return (RBUF) /* \_SB_.GPIO._CRS.RBUF */
}
Method (_STA, 0, NotSerialized)
{
Return (0x0F)
}
}
Device (BTNS)
{
Name (_HID, "PRP0001")
Name (_DDN, "GPIO buttons device")
Name (_CRS, ResourceTemplate () {
GpioIo (
Exclusive, // Not shared
PullUp, // Pull up the line
0, // Debounce timeout
0, // Drive strength
IoRestrictionInputOnly, // Only used as input
"\\_SB.GPIO", // GPIO controller
0) // Must be 0
{
x0, // GPIO pin offset in
corresponding controller for Button 0
x1, // for Button 1, and so on
...
}
})
Name (_DSD, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package () {

...
}
})
// For more information about these bindings see:
// Documentation/devicetree/bindings/input/gpio-keys-polled.txt
// and Documentation/acpi/gpio-properties.txt.
Name (BTN0, Package () {
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),

Package () {"linux,input-type", 1},
Package () {"gpios", Package () {^BTNS, 0, 0, 1}}
}

}
}
After updating firmware you would need just an ACPI ID table to be
added to the GPIO driver. MFD driver should not be enumerated at all.

I have seen that this is a lot of work and I didn't think it was so
complicated!
To get the GPIO support for APU2/APU3 merged into the gpio subsystem.
I am little confused what i should do now. By the way I only have one
board (APU3).
> - you need to support both
That is not necessary from my point of view. I am fine if the driver
supports at least
the current BIOS version. And if the coreboot maintainer fixes the ACPI
problem
then we could extend the driver and add the ACPI stuff.
But this not in my hand, right?

I will have a look how to achieve this.
If we want to support all BIOS version.
And is a must have to get the driver into mainline.

I do not understand how I could fix this. I have no idea from ACPI.
I have not found any driver where I can inspire myself.

That's maybe coming next when the coreboot maintainers have their bios
fixed, right?

Done but I do not seen any advantage. I used the following driver as
basis.

I have fixed all the above hints from you now but using
"module_platform_driver" is no option.
I played around with them but the driver does not find any device. So I
need the init function
to add a platform device. Only if I do this way driver and device will
find and match. And I
see the gpios under /sys/class/gpio. So I think I need this?
I have not find any driver who has the same problems
I used the following drivers as my basis:
https://github.com/torvalds/linux/blob/master/drivers/leds/leds-apu.c
https://github.com/torvalds/linux/blob/master/drivers/leds/leds-clevo-mail.c
They all use dmi and need init/exit for platform device register and
unregister
