From ef04070692a21633ec6a60f80c19b6af44b3cf47 Mon Sep 17 00:00:00 2001 From: Michael Hennerich Date: Tue, 24 Mar 2020 15:46:33 +0200 Subject: iio: adc: adi-axi-adc: add support for AXI ADC IP core This change adds support for the Analog Devices Generic AXI ADC IP core. The IP core is used for interfacing with analog-to-digital (ADC) converters that require either a high-speed serial interface (JESD204B/C) or a source synchronous parallel interface (LVDS/CMOS). Usually, some other interface type (i.e SPI) is used as a control interface for the actual ADC, while the IP core (controlled via this driver), will interface to the data-lines of the ADC and handle the streaming of data into memory via DMA. Because of this, the AXI ADC driver needs the other SPI-ADC driver to register with it. The SPI-ADC needs to be register via the SPI framework, while the AXI ADC registers as a platform driver. The two cannot be ordered in a hierarchy as both drivers have their own registers, and trying to organize this [in a hierarchy becomes] problematic when trying to map memory/registers. There are some modes where the AXI ADC can operate as standalone ADC, but those will be implemented at a later point in time.
