Subject: [PATCH v2 2/3] dt-bindings: spi: constrain minItems of clocks and clock-names
Date: Thu, 13 Jul 2023 17:00:14 +0800 [thread overview]
Message-ID: <20230713090015.127541-3-william.qiu@starfivetech.com> (raw)
In-Reply-To: <20230713090015.127541-1-william.qiu@starfivetech.com>
The SPI controller only need apb_pclk clock to work properly on JH7110 SoC,
so there add minItems whose value is equal to 1. Other platforms do not
have this constraint.
