Merge tag 'renesas-arm-dt2-for-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt

Second Round of Renesas ARM Based SoC DT Updates for v4.20

* RZ/G1M (r8a7743) based iWave G20D-Q7 board and camera daughter board
  - Move PCIe node out of common dtsi to allow reuse of the common dtsi
    on the iWave RZ/G1N board
* RZ/G1C (r8a77470) SoC: Add I2C4, SDHI2 and SMP support
* R-Car Gen1 based boards and R-Car Gen2 SoCs:
  - Enhance top-of-file comments to include SoC name
* RZ/N1D (r9a06g032) SoC:
  - Correct UART0 description and add all other UARTs

* tag 'renesas-arm-dt2-for-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: dts: iwg20d-q7-common: Move pciec node out of common dtsi
  ARM: dts: r8a77470: Add I2C4 support
