The code changes are mostly for 32-bit platforms and include:
- Lots of updates for the Nvidia Tegra platform, including
cpuidle, pmc, and dt-binding changes
- Microchip at91 power management updates for the recently added
sam9x60 SoC
- Treewide setup_irq deprecation by afzal mohammed
- STMicroelectronics stm32 gains earlycon support
- Renesas platforms with Cortex-A9 can now use the global timer
- Some TI OMAP2+ platforms gain cpuidle support
- Various cleanups for the i.MX6 and Orion platforms, as well as
Kconfig files across all platforms
