Please submit patches using subject lines reflecting the style for the subsystem, this makes it easier for people to identify relevant patches. Look at what existing commits in the area you're changing are doing and make sure your subject lines visually resemble what they're doing. There's no need to resubmit to fix this alone.

Mark, The rtl prefix really is as close as it gets. This is being developed on RTL838x and RTL839x, but the driver very likely also works on RTL8196C and RTL93xx series. There's no difference to the SPI block in those SoCs. Do you really want a different per-series compatible when the "IP block" was just copy-pasted between series in hardware?
