This is the pxa changes for v4.10 cycle. 

This cycle is covering :
  - some clock fixes common with sa1100 architecture
  - the consequence of the pxa_camera conversion to v4l2
  - a small irq related fix for pxa25x device-tree only

Merge tag 'pxa-for-4.10' of https://github.com/rjarzmik/linux into next/soc

This is the pxa changes for v4.10 cycle.

This cycle is covering :
 - some clock fixes common with sa1100 architecture
 - the consequence of the pxa_camera conversion to v4l2
 - a small irq related fix for pxa25x device-tree only

* tag 'pxa-for-4.10' of https://github.com/rjarzmik/linux:
  ARM: pxa: fix pxa25x interrupt init
  ARM: pxa: remove duplicated include from spitz.c
  ARM: pxa: em-x270: use the new pxa_camera platform_data
  ARM: pxa: ezx: use the new pxa_camera platform_data
  ARM: pxa: mioa701: use the new pxa_camera platform_data
  ARM: pxa: pxa_cplds: honor probe deferral
  ARM: sa11x0/pxa: get rid of get_clock_tick_rate
  watchdog: sa11x0/pxa: get rid of get_clock_tick_rate
  ARM: sa11x0/pxa: acquire timer rate from the clock rate
  clk: pxa25x: OSTIMER0 clocks from the main oscillator
