Initialisation of the LEDs is done with the LED class if CONFIG_LEDS_GPIO is selected or the General Purpose Input/Output (GPIO) interface if CONFIG_LEDS_GPIO is not selected. https://bugs.launchpad.net/bugs/651589 Signed-off-by: Signed-off-by: --- arch/arm/mach-omap2/board-igep0020.c | 170 ++++++++++++++++++++-------------- 1 files changed, 101 insertions(+), 69 deletions(-) diff --git a/arch/arm/mach-omap2/board-igep0020.c b/arch/arm/mach-omap2/board-igep0020.c index d55c57b..21bb77f 100644 --- a/arch/arm/mach-omap2/board-igep0020.c +++ b/arch/arm/mach-omap2/board-igep0020.c @@ -261,6 +261,77 @@ static struct omap2_hsmmc_info mmc[] = { {} /* Terminator */ };
