At the moment the MStar/SigmaStar support is only really capable of shell from an initramfs and not much else. Most of the interesting drivers are blocked on clock and pinctrl drivers and those are going to take me a little while to get cleaned up. Clock and pinctrl aren't needed for basic GPIO to work (all pins start off as GPIOs..) and it makes it possible to actually do something so this series adds everything that is needed for the main GPIO block in these chips.
