[PATCH v3] ARM: dts: aspeed: Adding Facebook Bletchley BMC

Howard Chiu howard10703049 at gmail.com
Wed Nov 17 18:20:06 AEDT 2021


Initial introduction of Facebook Bletchley equipped with
Aspeed 2600 BMC SoC.

Signed-off-by: Howard Chiu <howard.chiu at quantatw.com>

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
