The following patches add support for the Mercury+ AA1 with an
Arria 10 SoCFPGA.

This version differs from the previous one by removing the spi
flash node, renaming the memory and mdio nodes, adding gpio nodes,
and adding a bus number property to Synopsys DesignWare i2c
controller node.

Paweł Anikiel (4):
  i2c: check bus number property in DesignWare I2C Controller
  dt-bindings: add bus number property
  reset: socfpga: add empty driver allowing consumers to probe
  dts: socfpga: Add Mercury+ AA1 devicetree

Your header is a bit weird as you have 2 Message-IDs:
