Subject: [PATCH 0/2] iio: dac: ltc2632: add support for LTC2654 DAC family
Date: 10.03.2026 16:27
From: David Marinović <david.marinovic@xxxxxxxx>
To: jic23@xxxxxxxxxx
This patch series adds support for the Linear Technology LTC2654
quad DAC family to the existing ltc2632 driver.
The LTC2654 shares the same 24-bit SPI protocol as the existing
LTC2632/2634/2636 devices, requiring minimal additions to the
driver.
The LTC2654L-16 variant has been tested on a Phytec phyCORE-STM32MP1
board with the DAC connected via SPI1. The driver probes successfully
and all 4 channels are accessible via the IIO sysfs interface.
Patch 1 adds the driver support.
Patch 2 updates the DT bindings documentation.
