Subject: [PATCH v3 0/5] powerpc/pm: QorIQ deep sleep

Changes for v3:
* add mcke-gpios in dts to specify the GPIO pin which works as MCKE signal

Changes for v2:
* Ioremap every dts node used in the patches.
* Check the board compatible string to see if the board supports deep sleep.
* Can not reserve the first page of DDR memory, because PPC64 doesn't support
  changing the kernel base address. So still save and restore the first 128 bytes
  of DDR memory.
* Still save and restoer CCSR registers in kernel, because bootloader doesn't
  know what register values to restore
* Changed copyright and email address from freescale to NXP

Please refer to the version 1:
[1/4] powerpc/85xx: support sleep feature on QorIQ SoCs with RCPM
http://patchwork.ozlabs.org/patch/502549/

[2/4] powerpc: get the physical base address of DCSR
http://patchwork.ozlabs.org/patch/502551/
It is removed.

[3/4] powerpc: pm: add EPU FSM configuration for deep sleep
http://patchwork.ozlabs.org/patch/502548/

[4/4] powerpc: pm: support deep sleep feature on T104x
http://patchwork.ozlabs.org/patch/502550/
