Adding RTS5260 Support

[ghost]

Hi FireWolf:

First of all, thank you very much for implementing the Realtek SD card driver. I'm testing it on a Dell Precision 7530, which has the RTS5260 chip (10EC, 5260). I used the RTS525A class to experiment, however, it is not supported and recognized at all. I wonder if there is something I could do to help you implement the driver. The chip is most commonly found on Dell business laptops. Thank you again!

I used the RTS525A class to experiment, however, it is not supported and recognized at all.

This is expected, because each controller class contains chip-specific code that may not be compatible for other chips.

Try the attached driver and see if your chip can be recognized and work properly.

Thank you so much! The card reader worked well on Monterey, with your build and RealtekCardReaderFriend.

Does the SD card work properly as well? What's the read and write speed under macOS and other systems like Windows?

Yes, it is correctly recognized and has moderate writing speeds, as I only have an SDHC card to test. Sorry I don't have any UHS cards to report the maximum speed of the driver.
