Subject: [PATCH v2 3/4] interconnect: qcom: sm8250: Fix QUP0 nodes
The QUP0 BCM relates to some internal property of the QUPs, and should
be configured independently of the path to the QUP. In line with other
platforms expose QUP_CORE endpoints in order allow this configuration.
Fixes: 6df5b349491e ("interconnect: qcom: Add SM8250 interconnect provider driver")
Signed-off-by: Konrad Dybcio <konrad.dybcio@...aro.org>
