GPIO4_11 is on pin 152(MX6DL_PAD_KEY_ROW2) and not on pin
151(MX6DL_PAD_KEY_ROW1).
I found the error while booting a mainline kernel on APF6S SoM and
noticed the following message:
[ 2.609337] imx6dl-pinctrl 20e0000.iomuxc: pin MX6DL_PAD_KEY_ROW1
already requested by 20a8000.gpio:105; cannot claim for 20a8000.gpio:107
[ 2.621884] imx6dl-pinctrl 20e0000.iomuxc: pin-151 (20a8000.gpio:107)
status -22
[ 2.629303] spi_imx 2008000.ecspi: Can't get CS GPIO 107
With this patch, the message is gone and spi_imx driver probes correctly.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
