- 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.
