New Device Support:
- Supply device PCI IDs for Intel Broxton
Fix-ups:
- Move to clkdev_create() API; intel_quark_i2c_gpio
- Complete re-write of TI's TPS65912 Power Management IC (PMIC)
- Remove unnecessary function argument; axp20x
- Separate out bus related code; axp20x
- Coding Style changes; axp20x
- Allow more drivers to be compiled as modules
- Work around false positive 'used uninitialised' warning; db8500-prcmu
Bug Fixes:
- Remove do_div(); fsl-imx25-gcq
- Fix driver init when built-in; tps65010
- Fix clock-unregister leak; intel-lpss"
