openwrt/target/linux/bcm27xx/patches-4.19/950-0150-HID-hid-bigbenff-driver-for-BigBen-Interactive-PS3OF.patch
Adrian Schmutzler 7d7aa2fd92 brcm2708: rename target to bcm27xx 
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.

Subject: [PATCH] HID: hid-bigbenff: driver for BigBen Interactive
PS3OFMINIPAD gamepad
commit 256a90ed9e46b270bbc4e15ef05216ff049c3721 upstream.
This is a driver to fix input mapping and add LED & force feedback
support for the "BigBen Interactive Kid-friendly Wired Controller
PS3OFMINIPAD SONY" gamepad with USB id 146b:0902. It was originally
sold as a PS3 accessory and makes a very nice gamepad for Retropie.
