[PATCH 2/2] ARM: dts: aspeed: Add Delta AHE-50DC BMC
From: Zev Weiss
Date: Fri Nov 04 2022 - 21:33:43 EST
This is a 1U Open19 power shelf with six PSUs and 50 12VDC outputs via
LM25066 efuses. It's managed by a pair of AST1250 BMCs in a redundant
active/active configuration using a PCA9541 on each I2C bus to
arbitrate access between the two.
