Subject: [PATCH] dt-bindings: spi: qcom-qspi: Add minItems to interconnect-names
Date:   Sun, 27 Mar 2022 02:51:34 +0530

Qualcomm QSPI DT spec says interconnects has minimum length 1 and
maximum length 2. Same configuration will be applicable for
interconnect-names. Schema currently depicts interconnects length
correctly but not interconnect-names. It can have a single entry, which
is a valid case yet to be incorporated in the current configuration. The
schema tries to look for 2 names and fail for DTs with a single entry.
Thus, add minItems property to interconnect-names to fix it.

With the change applied, below interconnect-names values are possible:
['qspi-config'], ['qspi-config', 'qspi-memory']

Fixes: 8f9c291558ea ("dt-bindings: spi: Add interconnect binding for QSPI")
