This is a note to let you know that I have just added a patch titled spi: pl022: Specify 'num-cs' property as required in devicetree binding to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt16. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 18e63e7ee8fb3673edcebfa8efdd199127785c33 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> Date: Mon, 11 May 2015 12:20:18 -0300 Subject: spi: pl022: Specify 'num-cs' property as required in devicetree binding commit ea6055c46eda1e19e02209814955e13f334bbe1b upstream. Since commit 39a6ac11df65 ("spi/pl022: Devicetree support w/o platform data") the 'num-cs' parameter cannot be passed through platform data when probing with devicetree. Instead, it's a required devicetree property. Fix the binding documentation so the property is properly specified.
