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 8ae13d0b0d4bb4af99bec8c50152f0c8f5cbcc06 Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Tue, 13 Nov 2018 11:22:26 +0100 Subject: [PATCH] spi: pxa2xx: dt-bindings: Add ready GPIO signal This this is used to let the SPI master know that our FIFO is filled and we're ready to service a transfer. Only useful in slave mode. A signal like this is used by an embedded controller on a OLPC XO 1.75 machine, that happens to be a SPI master.
