Will do for v3. I did actually include a changelog in the individual
patches but I can collate that here.
clk: mvebu: support for 98DX3236 SoC
- Update devicetree binding documentation for new compatible string
arm: mvebu: support for SMP on 98DX3336 SoC
- Document new enable-method value
- Correct some references from 98DX4521 to 98DX3236
pinctrl: mvebu: pinctrl driver for 98DX3236 SoC
- include sdio support for the 98DX4251
arm: mvebu: Add device tree for 98DX3236 SoCs
- Update devicetree binding documentation to reflect that 98DX3336 and
984251 are supersets of 98DX3236.
- disable crypto block
- disable sdio for 98DX3236, enable for 98DX4251
arm: mvebu: Add device tree for db-dxbc2 and db-xc3-24g4xg boards
- None
