r360293: Reorder initialization steps for given pin. If pin is switched from fixed function to GPIO, it should have prepared direction, pull-up/down and default value before function gets switched. Otherwise we may produce unwanted glitch on output pin. Right order of drive strength settings is questionable, but I think that is slightly safer to do it also before function switch. r360461: Multiple fixes for rockchip iodomain driver: - always initialize selector of voltage signaling standard. Various versions of U-boot leaves voltage signaling standard settings for PMUIO2 domain in different state. Always initialize it into expected state. - start the driver as early as possible, the IO domains should be initialized before other drivers are attached. - rename RK3399 register to its name founds in TRM.
