You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >>From 007773e16a6f3f49d1439554078c3ba8af131998 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Wed, 11 Dec 2019 20:57:30 +0100 Subject: [PATCH] spi: nxp-fspi: Ensure width is respected in spi-mem operations 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.
