Merge tag 'v7.1-rockchip-dts32-2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into soc/dt

Support for the RV1103B SoC and the Onion Omega4 board using it.
While the RV1103B only got a B-extension to its name, the SoC internals
were reworked heavily. So likely it's mainly pin compatible to the
non-B variant.

The dt-binding for the RV1103B clock driver is shared with the clock-
driver branch going into the clock-tree.

* tag 'v7.1-rockchip-dts32-2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  ARM: dts: rockchip: Add Onion Omega4 Evaluation Board
  dt-bindings: arm: rockchip: Add Omega4 Evaluation board
  ARM: dts: rockchip: Add support for RV1103B
  dt-bindings: soc: rockchip: grf: Add RV1103B compatibles
  dt-bindings: clock: rockchip: Add RV1103B CRU support
