"Changes to existing drivers:
- Use of managed resources - omap, twl4030, ti_am335x_tscadc
- Advanced error handling - omap
- Rework clk management - omap
- Device Tree (re-)work - tc3589x, pm8921, da9055, sec
- IRC management overhaul and !BROKEN - pm8921
- Convert to regmap - ssbi, pm8921
- Use simple power-management ops - ucb1x00
- Include file clean-up - adp5520, cs5535, janz, lpc_ich,
- lpc_sch, max14577, mcp-sa11x0, pcf50633-adc, rc5t583,
