The pinmux bits for GPIO2-B7 is recalculated so it remain unchanged. The pinmux bits for those pins are not explicitly specified in RK3328 TRM, however we can get hint from pad name and its correspinding IOMUX setting for pins in interface descriptions. The correspinding IOMIX settings for GPIO2-B0 to GPIO2-B6 can be found in the same row next to occurrences of following pad names in RK3328 TRM. GPIO2-B0: IO_SPIclkm0_GPIO2B0vccio5 GPIO2-B1: IO_SPItxdm0_GPIO2B1vccio5 GPIO2-B2: IO_SPIrxdm0_GPIO2B2vccio5 GPIO2-B3: IO_SPIcsn0m0_GPIO2B3vccio5 GPIO2-B4: IO_SPIcsn1m0_FLASHvol_sel_GPIO2B4vccio5 GPIO2-B5: IO_ I2C2sda_TSADCshut_GPIO2B5vccio5 GPIO2-B6: IO_ I2C2scl_GPIO2B6vccio5 This fix has been tested on NanoPi R2S for fixing confliting pinmux bits between GPIO2-B7 with GPIO2-B5.
