Merge tag 'at91-cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into next/cleanup
Pull "Second batch of cleanup for 4.1" from Nicolas Ferre:
- remove unused matrix header files
- dbgu + chip identification: new driver for SoC detection
this allow to remove all additional io mapping
- remove old non-standard AT91 setup code
First batch of cleanup for 4.1:
- little phy fixup that is not needed anymore
- hudge cleanup of the PM code:
- removal of "use slow clock" option => always use this for suspend to RAM
- quicker suspend as the asm function is copied only once to SRAM
- use of the same asm function for "standby" and "mem" types of suspend
actions
- adaptation to the ARMv7 processors
