ramips: rt305x: add support for the Asus WL-330N3G board
This patch adds support for the ASUS WL-330N3G Comparing to the WL-330N, It have 32MB ram, usb support and a bicolor led. The bi-color led is driven by 2 gpio. I don't know how to handle this, so I simply made 2 leds : one red, one blue. But the red light takes precedence over the blue one according to the chart below. r = led is red b = led is blue 0 = led is off xy= x->r for red, b for blue led, y->value of brightness in /sys/class/leds/x/brughtness initial state action led gpio state r0 b0 r0->r1 r r0 b0 r0 b0 b0->b1 b r0 b1 r1 b0 r1->r0 0 r0 b0 r1 b0 b0->b1 r r1 *b1* r1 b1 r1->r0 b r0 b1 r1 b1 b1->b0 r r1 b0 r0 b1 r0->r1 r r1 *b1* r0 b1 b1->b0 0 r0 r0 Signed-off-by: Frédéric Leroy <fredo@starox.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@31450 3c298f89-4303-0410-b956-a3cf2f4a3e73
