The V853 family has multiple package variants, from BGA to QFN88. The latter has co-packaged DRAM and fewer pins, and less features (pin muxes). All family members can be supported by a single driver, as the available pins with allowed muxes is the same across the devices. This new pinctrl driver depends on the new sunxi device-tree based mux support patch series [1].
