Subject: [PATCH v2 1/2] dt-bindings: iio: adc: ti,ads7038: Add description for ADS7038
Date: Thu, 5 Oct 2023 05:54:54 +0200 [thread overview]
Message-ID: <20231005035933.31016-1-andre.werner@systec-electronic.com> (raw)
From: Andre Werner <andre.werner@systec-electronic.com>
Add basic description for ADS7x38 ADC devices. The driver does only
support a very basic set of functionalities provided by the chip.
Also, the example in the description covers only a setup for ADS7038 devices
while the driver structure will support both ADS7038 (SPI) and ADS7138 (I2C) devices.
Signed-off-by: Andre Werner <andre.werner@systec-electronic.com>
