Merge tag 'omap-for-v4.1/fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Merge "omap fixes against v4.1-rc1" from Tony Lindgren:

Fixes for omaps, mostly a fix for power power consumption
creeping up during idle, and two l3-noc device fixes:

- Fix power consumption creeping up with I2C4 staying on
- Fix n900 microphone bias voltages
- Fix dra7 l3-noc for host clock
- Fix omap5 l3-noc id address decoding

The rest are all just minor dts fixes:

- Fix changed EXTCON_USB_GPIO_USB in defconfig
- Fix missing isp and iva #iommu-cells property
- Various beagle x15 dts fixes for pre-production changes
- Fix am437x-sk display dts entries
