This patch series adds support Renesas R-Car S4-8 UFS controller.
This controller has some restrictions so adds some quirks for it.
Before using this driver, we have to initialize a clock generator
on the environment board (named "Spider") by using the commands of
U-Boot like below:
 => i2c dev 0
 => i2c mw 0x6c 0x26 0x05
 => i2c olen 0x6c 2
 => i2c mw 0x6c 0x26c 0x2e

To use the UFS controller, we need the following patch too:

Thanks for the patches. Somehow I did not got entire set (bindings
missing) and I cannot find any of them on lore.kernel.org. Did you have
some bounces or sending troubles?

Best regards,
Krzysztof
