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. Despite, since subtargets range from bcm2708 to bcm2711, it seems appropriate to use bcm27xx instead of bcm2708 (again, as already done for BOARDNAME). This also renames the packages brcm2708-userland and brcm2708-gpu-fw. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

Subject: [PATCH] overlays: mcp23017: Add option for not connecting the
|
|
int GPIO
|
|
|
|
The interrupt GPIO is optional to the driver, therefore add an
|
|
option to not configure it.
