Subject: [PATCH 4/6] dt-bindings: iio: adc: Add the binding documentation for NXP IMX8QXP ADC
Date: Tue, 31 Aug 2021 01:21:38 +0800	[thread overview]
Message-ID: <20210830172140.414-5-caihuoqing@baidu.com> (raw)
In-Reply-To: <20210830172140.414-1-caihuoqing@baidu.com>

The NXP i.MX 8QuadXPlus SOC has a new ADC IP, so add the binding
documentation for NXP IMX8QXP ADC
