[PATCH v2 3/3] ARM: dts: aspeed: System1: IBM system1 BMC board

Ninad Palsule
2024-01-08T20:42:48Z

From: Andrew Geissler <geissonator@yahoo.com>

Add a device tree for IBM system1 BMC board. It uses AST2600 SOC.
- Added base board
- Added i2c devices and muxes.
- Added different voltage regulators.
- Added GPIO pin assignements, GPIO expansion devices
- Added LED brinker devices
- Added Fan controllers
- Added EEPROM/VPD
- Added Power supplies
- Added Humidity, pressure and temperature sensors.
- Added Trusted platform module(TPM) chip

Tested:
This board is tested using the simics simulator.

v2:
- Incorporated review comments from Conor Dooley, Jarkko Sakkinen,
Guenter Roeck, Rob Herring, Krzysztof Kozlowski
- Merge all patches into single patch.
- Split the trivial device patch.
- Cleanup commit messages.
- Fixed bootargs string.
- Fixed node names.
- Dropped tpm schema patch as it is covered by Lukas's patch.
- Dropped "tpm: tis-i2c: Add more compatible strings" patch and
send it as a separate patch.
