The aim of this patch set is to introduce tracing for PORTCS writes and implement a Port Register Set struct. Introduces a new struct for the Host Controller USB Port Register Set. The current implementation accesses these registers through a single '__le32' pointer, which, in conjunction with a macro, navigates to the specific register using (base address + offset). Currently, how its accessed | Register Name -------------------------------------------------------------------------- port->addr | Port Status and Control port->addr + PORTPMSC | Port Power Management Status and Control port->addr + PORTLI | Port Link Info port->addr + PORTHLPMC | Port Hardware LPM Control After, how its accessed | Register Name -------------------------------------------------------------------------- port->port_reg->portsc | Port Status and Control port->port_reg->portpmsc | Port Power Management Status and Control port->port_reg->portli | Port Link Info port->port_reg->porthlmpc | Port Hardware LPM Control These changes make it easier for future modification and their review. Note: I have chosen to split the struct changes across three separate commits due to the substantial number of modified lines. Personally, I find that minor typos are more likely to occur when dealing with larger patches. However, I am open to consolidating these patches into a single commit after review.
