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 80b444e57948ea4bd5a89fb1f8c404ddab6c1973 Mon Sep 17 00:00:00 2001 From: Thor Thayer Date: Mon, 10 Oct 2016 09:25:25 -0500 Subject: [PATCH] spi: dw: Set GPIO_SS flag to toggle Slave Select on GPIO CS The Designware SPI master requires slave selection before the transfer can begin [1]. This patch uses the new master flag to indicate both the GPIO CS and the internal chip select should be used.
