It aims to fix CAN-FD operation after resume from s2ram on systems where PSCI powers down the SoC. The last patch is marked RFC, as it causes a regression on R-Car Gen4. More details can be found in that patch. This has been tested on Ebisu-4D (R-Car E3) and White Hawk (R-Car V4H). Thanks for your comments!
