As always, this tends to be one of our bigger branches. There are lots of
updates this release, but not that many jumps out as something that needs
more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- More graphics DT pieces falling into place on Exynos, bridges, clocks.
- Plenty of DT updates for Qualcomm platforms for various IP blocks
- Some churn on Tegra due to switch-over to tool-generated pinctrl data
- Misc fixes and updates for Atmel at91 platforms
- Various DT updates to add IP block support on Broadcom's Cygnus platforms
- More updates for Renesas platforms as DT support is added for various IP
blocks (IPMMU, display, audio, etc).

- Finally, remove the deprecated wl12xx_platform_data struct
Note that da850 board file code that still uses the platform data,
