Subject: [PATCH v2 03/12] iio: adc: at91-sama5d2_adc: adapt the driver for sama7d65
Date: Tue, 23 Jun 2026 16:29:35 +0530 [thread overview]
Message-ID: <20260623105944.128840-4-varshini.rajendran@microchip.com> (raw)
In-Reply-To: <20260623105944.128840-1-varshini.rajendran@microchip.com>
Add support for sama7d65 ADC. The differences are highlighted with the
compatible. The calibration data layout is the main difference.
