From 464fa29e8f3fb2c209647efbb365470b35daec38 Mon Sep 17 00:00:00 2001 From: William Qiu Date: Thu, 2 Mar 2023 18:52:20 +0800 Subject: [PATCH 092/122] dt-bindings: qspi: cdns,qspi-nor: constrain minItems/maxItems of resets The QSPI controller needs three reset items to work properly on JH7110 SoC, so there is need to change the maxItems's value to 3 and add minItems whose value is equal to 2. Other platforms do not have this constraint.
