#17062: LEDs mapped to wrong GPIOs on WRT54GL
------------------------------------------+--------------------------------
Reporter: anonymous | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Barrier Breaker
Component: kernel | (trunk)
Keywords: wrt54g wrt54gl gpio led leds | Version: Trunk
------------------------------------------+--------------------------------
Remember Ticket #16991 "LEDs mapped to wrong GPIOs on WRTSL54GS"? Same
stuff again, but this time with a WRT54GL v1.1
In the mentioned ticket I thought it is weird that (before the fix) the
WRTSL54GS had the GPIO layout of the WRT54G(S). - I discovered that the
entries are indeed switched with each other.
Since WRTSL54GS was already fixed in r41516 , now only the WRT54G* series
is affected.
[LED name] - > [Actual toggled LED]
bcm47xx:unk:power - > Power LED (correct)
bcm47xx:unk:dmz -> WLAN LED
bcm47xx:orange:wps -> DMZ LED
bcm47xx:white:wps -> <Nothing>
Story time:
So I flashed my old WRT54GL with a recent trunk version and discovered the
LEDs were wrong too (see table above).
I checked "target/linux/brcm47xx/patches-3.10/140-MIPS-BCM47XX-add-button-
and-led-configuration-for-so.patch" once again and saw my suspicion
confirmed: "wrt54gsv1" and "wrtsl54gs" were both added in this patch, but
the GPIOs are switched with each other.
In "target/linux/brcm47xx/patches-3.10/144-MIPS-BCM47XX-Distinguish-
WRT54G-series-devices-by-bo.patch", "wrt54gsv1" was renamed to
"wrt54g_generic" and the wrong GPIO layout is used for almost all WRT54G*
devices since then.
