Subject: [PATCH 0/5] Add GPIO support for MStar/SigmaStar ARMv7

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.

Daniel Palmer (5):
  dt-bindings: gpio: Binding for MStar MSC313 GPIO controller
  dt-bindings: gpio: Add a binding header for the MSC313 GPIO driver
  gpio: msc313: MStar MSC313 GPIO driver
  ARM: mstar: Add gpio controller to MStar base dtsi
  ARM: mstar: Fill in GPIO controller properties for infinity
