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] media: bcm2835-unicam: Fix one-to-many mapping for
|
|
YUYV formats
|
|
|
|
V4L2 format V4L2_PIX_FMT_YUYV maps to both MEDIA_BUS_FMT_YUYV8_2X8
|
|
and MEDIA_BUS_FMT_YUYV8_1X16. The change to not cache the active
|
|
formats also meant that we only ever found the first variant of
|
|
the mediabus format when trying to setup the device.
|
|
|
|
Flag the formats that have other representations, and ensure
|
|
that the format conversion checks whether the found format
|
|
matches one supported by the sensor before returning it.
