PATCH v2 1/1 ARM: Kirkwood: enable GPIO fan alarm support for 2Big Network v2

On the LaCie 2Big Network v2 (net2big_v2) board, the fan alarm is not wired to the I2C fan controller but to a separe GPIO. This GPIO can be controlled by using the gpio-fan driver.

This patch adds the gpio-fan alarm description in the net2big_v2 DTS.

Hi Simon,

On the LaCie 2Big Network v2 (net2big_v2) board, the fan alarm is not wired to the I2C fan controller but to a separe GPIO. This GPIO can be controlled by using the gpio-fan driver.

This patch adds the gpio-fan alarm description in the net2big_v2 DTS.

Now that the driver part had been merged, I applied this patch on mvebu/dt.

Thanks,

Gregory
