This patch is a workaround for a SoC bug where an internal abort command may timeout. In v2 hw, the channel should become idle in order to finish abort process. If the target side has been sending HOLD, host side channel failed to complete the frame to send, and can not enter the idle state. Then internal abort command will timeout. As this issue is only in v2 hw, we deal with it in the hw layer. Our workaround solution is: If abort is not finished within a certain period of time, we will check HOLD status. If HOLD has been sending, we will send break command. Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Xiaofei Tan <tanxiaofei@huawei.com> Signed-off-by: Martin K.
