The Olimex Olinuxino board has a user led connected to SSP1_DETECT. But since this pin is listed in mmc0_pins_fixup, it is already claimed by MMC driver and this results in this error during boot: [ 1.390000] imx23-pinctrl 80018000.pinctrl: pin SSP1_DETECT already requested by 80010000.spi; cannot claim for leds [ 1.400000] imx23-pinctrl 80018000.pinctrl: pin-65 (leds) status -22 [ 1.410000] imx23-pinctrl 80018000.pinctrl: could not request pin 65 (SSP1_DETECT) from group led_gpio2_1.0 on device 80018000.pinctrl [ 1.420000] leds-gpio leds: Error applying setting, reverse things back [ 1.430000] leds-gpio: probe of leds failed with error -22 This fix it, introduce mmc0_sck_cfg and switch the Olinuxino board to it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
