More testing after kernel upgrade to 5.4 uncovered a regression: the user led is not present anymore due to a pin mux "collision" in device tree. A patch sent to upstream kernel was accepted now. Integrate this pending fix as platform specific patch so that user led is available again. Signed-off-by: Michael Heimpold <mhei@heimpold.de>

Subject: [PATCH] ARM: dts: imx23: introduce mmc0_sck_cfg
|
|
|
|
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.
