Subject: [PATCH v5 2/3] dt-bindings: iio: adc: Add Allwinner D1/T113s/R329/T507 SoCs GPADC
Date: Sat, 10 Jun 2023 23:19:49 +0300 [thread overview]
Message-ID: <20230610202005.1118049-3-bigunclemax@gmail.com> (raw)
In-Reply-To: <20230610202005.1118049-1-bigunclemax@gmail.com>
From: Maxim Kiselev <bigunclemax@gmail.com>
Allwinner's D1/T113s/R329/T507 SoCs have a new general purpose ADC.
This ADC is the same for all of this SoCs. The only difference is
the number of available channels.
