[PATCH 0/2] ARM: dts: updates for omap3-overo

[Florian Vaussard]

Hello,

This series adds support to omap3-overo for the onboard NAND memory, and
restore the default trigger for the pwm-led provided by TWL4030.

Best regards,

Florian

[PATCH 2/2] ARM: dts: omap3-overo: add default trigger for TWL4030 LED

[Florian Vaussard]

Commit c971ff1 'leds: leds-pwm: Defer led_pwm_set() if PWM can sleep'
fixed a crash when using a trigger with a pwm-led provided by an
external chip. Now it is safe to add the default trigger according
to board-overo.c.
