This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

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.
