According to rk3308b TRM, this pinctrl much the same as rk3308's, but with additional iomux routes and 3bit iomuxes selected via gpio##_sel_src_ctrl registers. Downstream kernel [1] managed this SoC's with rk3308b_soc_data_init, wich picked configuration based on cpuid. Upstream pinctrl patches droped soc init function. The function rk3308b_soc_sel_src_init sets up gpio##_sel_src_ctrl registers, making SoC to use 3bit iomuxes over some 2bit old ones. These patches have been tested on Radxa's ROCK Pi S, one based on rk3308 and the other on rk3308b (from the latest batches). For the new boards fixes broken spi1 clk. Similar effort [2] was made several years ago, but without keeping base rk3308 SoC pinctrl support.
