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

[Chenhui Zhao]

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:
