Subject: [PATCH v3 2/3] dt-bindings: iio: adc: Add the binding documentation for NXP IMX8QXP ADC
Date: Tue, 7 Sep 2021 09:57:22 +0800 [thread overview]
Message-ID: <20210907015724.1377-3-caihuoqing@baidu.com> (raw)
In-Reply-To: <20210907015724.1377-1-caihuoqing@baidu.com>
The NXP i.MX 8QuadXPlus SOC has a new ADC IP, so add the binding
documentation for NXP IMX8QXP ADC.
Signed-off-by: Cai Huoqing <caihuoqing@baidu.com>
