Subject: accel/qaic: Add ipc_router channel
X-Git-Tag: v6.13-rc1~122^2~18^2~42
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2af5deb614e7bc9367aadf9105e37c8299120af4;p=thirdparty%2Fkernel%2Flinux.git

accel/qaic: Add ipc_router channel

The ipc_router channel allows AF_QIPCRTR clients and services to
communicate with the AIC100 device. The ipc_router MHI transport layer
expects the channel to be named exactly "IPCR".
