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: tc358743: Increase FIFO level to 374.
|
|
|
|
The existing fixed value of 16 worked for UYVY 720P60 over
|
|
2 lanes at 594MHz, or UYVY 1080P60 over 4 lanes. (RGB888
|
|
1080P60 needs 6 lanes at 594MHz).
|
|
It doesn't allow for lower resolutions to work as the FIFO
|
|
underflows.
|
|
|
|
374 is required for 1080P24-30 UYVY over 2 lanes @ 972Mbit/s, but
|
|
>374 means that the FIFO underflows on 1080P50 UYVY over 2 lanes
|
|
@ 972Mbit/s.
