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 941be723735113028361c4664cd10134d3d27006 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Fri, 8 Nov 2019 15:07:40 +0100 Subject: [PATCH] spi: zynq-qspi: Keep the bitfields naming consistent Most of the bits/bitfields #define'd in this driver are composed with: 1/ the driver prefix 2/ the name of the register they apply to Keep the naming consistent by applying this rule to the CONFIG register internals. These definitions will be used in a following change set.
