From ba6ad897c3dc7b30b13605b404db61e427e1f47d Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Tue, 14 Jan 2020 16:46:13 +0100 Subject: [PATCH] spi: spi-fsl-qspi: Ensure width is respected in spi-mem operations [ Upstream commit b0177aca7aea7e8917d4e463334b51facb293d02 ] Make use of a core helper to ensure the desired width is respected when calling spi-mem operators. Otherwise only the SPI controller will be matched with the flash chip, which might lead to wrong widths. Also consider the width specified by the user in the device tree.
