From a6fa8475511b556ef1130de7529c63acccc8fc65 Mon Sep 17 00:00:00 2001 From: Arnaud Ebalard Date: Sat, 22 Nov 2014 00:46:10 +0100 Subject: [PATCH] arm: mvebu: define and use common Armada 370 SPI pinctrl settings This patch defines common Armada 370 pinctrl settings for spi0 and spi1 interfaces: spi0: MPP33-36 as default, MPP32,63-65 as available alternate config spi1: MPP49-52 as default Currently, the Armada 370 DB .dts file has no explicit pinctrl info for the spi0 interface used to access the flash on the board. The patch fixes that by also adding explicit pinctrl info (MPP32,63-65) for this SPI interface. Note: this patch has the potential to break out-of-tree users w/o specific pinctrl settings for their spi interfaces if the default above does not match their config.
