Initial introduction of Facebook Bletchley equipped with
Aspeed 2600 BMC SoC.
Signed-off-by: Howard Chiu <[email protected]>
Change since v5:
- Add an EEPROM on i2c-7
- Change address of FUSB302 to 0x22
- Assign interrupt pin to FUSB302
- Rework pin assignment of pca9539
Change since v4:
- Change address of TMP421 on i2c-12 to 0x4d
Change since v3:
- Add a TMP421 on i2c-10
Change since v2:
- Remove uart5 workaround
- Remove gpio nodes of pca9552/pca9539
- Modify gpio-line-name of led/power/presence pins with openbmc pattern
- Add MP5023 devices
Change since v1:
- Keep sorted in Makefile
- Change baudrate to 57600 from 115200
- Rename node *-ember to *-amber
- Use openbmc-flash-layout-128.dtsi

I like to have some background on the machine, as it provides context
for the review. Is it a x86 server? A x86 switch? Of course if this
information is confidential then that's fine to omit it, only provide
what you can.

the commit message when added to the kernel.
If the information is relevant, then put it in the commit message

Your reg property is 22, but the unit address is 54. These need to
math or you will get a warning from the device tree compiler:

A number of the GPIOs do not have defined openbmc patterns for them yet. The
names you have chosen are ok for now, but we will be changing them as we refine
development of this machine further.

Thanks for reviewing.
Howard, I'm merging patches for v5.17 but I can't apply this until you
fix the warnings I mentioned.

Hi Joel
Bletchley platform needs to support fan control.
Since Billy's patch for upstream is still under review, I can't add pwm/tach node into dts or the build would fail.
As you know, I had committed the pwm/tach driver for ast26xx to OpenBMC linux, could I commit the dts to OpenBMC linux instead of upstream for early build?

I'd suggest no, omit those features for now, and you can add them in
once we have a driver. The device tree bindings for the tach/pwm need
some work before they can be approved.
When I asked you to fix the patch, I was referring to the usb-c
warnings that I posted about the other week.

The driver you mentioned is for OpenBMC Linux or upstream?
If it is for OpenBMC, the upstream robot will reject my DTS because the aspeed-g6.dtsi did not contain pwm/tach node.
If it is for upstream, it will be a long time that OpenBMC Linux won't have tach driver for ast2600 series, and my patch to commit with Billy's early driver for OpenBMC Linux is also meaningless.

I will fix it and others you mentioned in the v7 patch.
