This is a fairly simple series to add support for the MStar MSC313
uarts found in MStar/SigmaStar ARMv7 based SoCs.

I have been using this for years now but I held off sending it because
I wasn't entirely sure the uart was actually a DW based design.

We got documentation recently and it refers to this being a "DW UART"
so I'm pretty sure it is now.

Daniel Palmer (4):
  dt-bindings: serial: snps-dw-apb-uart: Add MStar MSC313 uarts
  serial: 8250_dw: Add MStar MSC313 quirk
  ARM: dts: mstar: Switch pm_uart to mstar,msc313-uart
  ARM: dts: mstar: Add second UART to base dtsi.
