ARM: SoC fixes for 4.1-rc2
A few patches have come up since the merge window. The largest one is a
rewrite of the PXA lubbock/mainstone IRQ handling. This was already
broken in 2011 by a change to the GPIO code and only noticed now.
The other changes contained here are:
MAINTAINERS file updates:
- Ray Jui and Scott Branden are now co-maintainers for some of the
mach-bcm chips, while Christian Daudt and Marc Carino have stepped
down.
- Andrew Victor is no longer maintaining at91. Instead, Alexandre
Belloni now becomes an official maintainer, after having done a
bulk of the work for a while.
- Baruch Siach, who added the mach-digicolor platform in 4.1
is now listed as maintainer
- The git URL for mach-socfpga has changed
Bug fixes:
- Three bug fixes for new rockchip rk3288 code
- A regression fix to make SD card support work on certain ux500
boards
- multiple smaller dts fixes for imx, omap, mvebu, and shmobile
- a regression fiix for omap3 power consumption
- a fix for regression in the ARM CCI bus driver
Configuration changes:
- more imx platforms are now enabled in multi_v7_defconfig
