From 2cd36711e2b9714c0bb500b4060714666f37ca2c Mon Sep 17 00:00:00 2001 From: Fabio Estevam <fabio.estevam@freescale.com> Date: Fri, 11 Apr 2014 09:09:39 -0300 Subject: [PATCH] ARM: dts: imx6sl-evk: Add an entry for MX6SL_PAD_ECSPI1_SS0__GPIO4_IO11 In case the bootloader has incorrectly configured the ALT mode of MX6SL_PAD_ECSPI1_SS0 pad, we end up with the following probe error: m25p80 spi0.0: found mr25h256, expected m25p32 m25p80 spi0.0: mr25h256 (32 Kbytes) In order to avoid this issue, add an entry for MX6SL_PAD_ECSPI1_SS0 pad, so that kernel configures the ECSPI chip select as GPIO functionality, which results in correct SPI NOR probe.
