Subject: [PATCH v2 1/3] dt-bindings: qspi: cdns,qspi-nor: Add clocks for StarFive JH7110 SoC
Date: Fri, 2 Jun 2023 16:49:23 +0800	[thread overview]
Message-ID: <20230602084925.215411-2-william.qiu@starfivetech.com> (raw)
In-Reply-To: <20230602084925.215411-1-william.qiu@starfivetech.com>

The QSPI controller needs three clock items to work properly on StarFive
JH7110 SoC, so there is need to change the maxItems's value to 3. Other
platforms do not have this constraint.
