Subject: [PATCH] MIPS: BCM47XX: Add Luxul XAP1500/XWR1750 WiFi LEDs
|
||
|
|
|
||
|
|
Some Luxul devices use PCIe connected GPIO LEDs that are not available
|
||
|
|
until the PCI subsytem and its drivers load. Using the same array for
|
||
|
|
these LEDs would block registering any LEDs until all GPIOs become
|
||
|
|
available. This may be undesired behavior as some LEDs should be
|
||
|
|
available as early as possible (e.g. system status LED). This patch will
|
||
|
|
allow registering available LEDs while deferring these PCIe GPIO
|
||
|
|
connected 'extra' LEDs until they become available.
