From a433c2cbd75ab76f277364f44e76f32c7df306e7 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Thu, 27 Jan 2022 10:18:01 +0100 Subject: spi: spi-mem: Add an ecc parameter to the spi_mem_op structure Soon the SPI-NAND core will need a way to request a SPI controller to enable ECC support for a given operation. This is because of the pipelined integration of certain ECC engines, which are directly managed by the SPI controller itself. Introduce a spi_mem_op additional field for this purpose: ecc. So far this field is left unset and checked to be false by all the SPI controller drivers in their ->supports_op() hook, as they all call spi_mem_default_supports_op().
