Implement trace event support to enhance logging functionality for register access and the transfer control descriptor (TCD) context. This will enable more comprehensive monitoring and analysis of system activities Signed-off-by: Frank Li <Frank.Li@nxp.com> Link: https://lore.kernel.org/r/20240425205947.3436501-1-Frank.Li@nxp.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
