[PATCH v4 5/5] arm64: dts: qcom: sm8650: Add Broadcast_AND register in LLCC block
From: Unnathi Chalicheemala
Date: Fri Mar 29 2024 - 17:54:28 EST
Chipsets before SM8450 have only one broadcast register (Broadcast_OR)
which is used to broadcast writes and check for status bit 0 only in
all channels.
>From SM8450 onwards, a new Broadcast_AND region was added which checks
for status bit 1. This hasn't been updated and Broadcast_OR region
was wrongly being used to check for status bit 1 all along.
Hence mapping Broadcast_AND region's address space to LLCC in SM8650.
