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] spi: Make GPIO CSs honour the SPI_NO_CS flag
|
|
|
|
The SPI configuration state includes an SPI_NO_CS flag that disables
|
|
all CS line manipulation, for applications that want to manage their
|
|
own chip selects. However, this flag is ignored by the GPIO CS code
|
|
in the SPI framework.
|
|
|
|
Correct this omission with a trivial patch.
|
|
|
